From the author: Hello, dear readers! Finding a budget alternative to traditional heating is a task for many business owners. Popular electric heaters do not solve the task of saving the family budget, so gas and solid fuel heaters come first.
The operation of such structures is much more profitable and easier to learn. We invite you to familiarize yourself with several technologies for making a gas heater with your own hands, taking into account safety requirements and ease of use at home and in the utility area.
Advantages and disadvantages
Whatever type of home heating heater you choose to implement with your own hands, regardless of the complexity of the design and layout, you must ensure that the following requirements are met:
- ease of assembly and transportation, ergonomics,
- safety and reliability during operation,
- efficiency in the process of consuming energy, gas or solid fuels,
- high efficiency and productivity,
- availability of structural elements and materials for DIY assembly,
- durability.
Depending on the functional requirements, you can choose the right type of heater.
Advice: infrared, quartz heaters and electric convectors are considered the most effective, safe for home use and most common among homeowners.
The main advantages of homemade heating devices for different types of premises, residential and non-residential, are:
- use of inexpensive and accessible materials for construction,
- individual calculation of operating needs and high efficiency,
- quality and ease of assembly.
When purchasing a model of a factory heater, it is not always possible to obtain exactly the characteristics that will satisfy your need for heating the room. Basic requirements for a gas-type heater
You can safely use a gas-type heating device if you adhere to the following requirements:
- all operating elements responsible for gas supply must be factory-made and carefully checked for integrity,
- the design provides and implements simple and understandable methods for activating/deactivating the unit,
- The design and layout of a gas heater must be carefully thought out.
With rare exceptions, gas heaters are very mobile, take up little space and are easy to assemble. Let's talk about the advantages of gas heating structures:
- ease of operation and assembly,
- high efficiency and efficiency,
- minimal damage to nature and households, products of complete combustion are practically harmless, the main thing is not to forget about the importance of installing ventilation,
- quick heating of the room,
- natural gas, liquefied or network gas, is considered the most affordable of all energy carriers,
- Some factory and home-made models also combine electronic components necessary for the operation of control units and ventilation, but the costs will not affect the family budget.
Briefly about the requirements
When taking on a particular project, it is important to remember that the main thing is your own safety. That is why there are very specific requirements for garage stoves - made of metal, gas cylinders, or any material in general - and ignoring them entails an equally specific threat to your life
We have collected the main ones - remember:
- when installing a chimney, take care of the tightness of its channel;
- place the stove at a reasonable distance from flammable objects and liquids;
- do not use suspicious substances as fuel, as the vapors released during combustion can be harmful to your health;
- the exhaust valve must be no less than 10 cm in diameter;
- The recommended dimensions for standard potbelly stoves are 70x50x35 cm, while the volume of the structure should not exceed 12 liters.
Operating rules
Any heating design requires attention to detail, first of all, your personal safety. This is especially true for gas equipment, where it is necessary to take into account the chemical properties of the gas and the technical nuances of the design. What should you pay attention to first of all when operating a gas heater and what safety rules should you follow?
To avoid fire hazards, gas explosions, and poisoning, it is worth remembering the following rules:
- the absence of well-thought-out supply and exhaust ventilation or disruption of their operation can lead to the accumulation of unburned natural gas. Its toxicity is dangerous, it can cause poisoning and suffocation, and if the temperature changes and a flammable source appears, it can lead to an explosion and fire,
- during operation of the structure, you must not touch it, as it heats up to very high temperatures,
- Gas cylinders, according to safety regulations, should be stored strictly vertically and in a well-ventilated area,
- large cylinders are recommended to be installed in a separate room with the least traffic and a well-thought-out ventilation system,
- cylinders that are not in use must be stored in non-residential premises. It doesn't matter if they're empty or full,
- When replacing a cylinder, you should always carry out a visual inspection for the integrity of parts and the tightness of joints. The best option is to apply a soap solution at the joints.
Despite the whole list of disadvantages, gas heaters are in great demand, creating a comfortable temperature in the room. With proper operation, prevention and control, even a self-made unit can serve productively for many years.
Appendix 1
Today I received another letter asking me to explain where to get capillaries and, in general, how to make an injector. It was even proposed to use electrical erosion. I had no idea that this could cause problems. So, I do it this way. First of all, I got used to using M3 screws for the injectors (a regular screw with a 3 mm metric thread). So, take your box of M3 screws, dump it out and distribute it in an even layer. Then take a magnet and pull out all the attached screws. As a result, you will be left with screws that do not tighten. The fact that they look the same as the others should not fool you. These are plated brass screws. In the photo under number 1. If there are no brass M3s, nothing prevents you from doing this with M4.
Next, you have five options: - immediately drill a hole with the required drill diameter. But this is for fairly large holes and with a precision drill. - drill on both sides of the screw with a large drill, but not all the way. Then pierce this jumper with a needle or drill it with a small drill. - drill with a large drill, and then fill the hole with PIC solder, and then work with it, which is much easier. - drill with a large drill, and then use POS solder to solder a stainless wire of the appropriate diameter coaxially into the screw. And then pull out the wire. And finally, you can solder a capillary of the appropriate diameter into the drilled hole using low-melting solder. So, capillaries, that is, thin tubes. Under the number 2 are capillaries from instrumentation instrument recorders. It’s unlikely that this advice will make you feel any better. But number 3 is the most realistic option. When the doctor gives you an injection, don’t groan, don’t feel sorry for yourself, but gather your willpower and ask the doctor to give you the needle as a souvenir. He will give it back, he doesn’t mind. Thus, over the course of your sick life and that of your loved ones, you will collect an extensive collection of capillaries. And if you are lucky enough to give injections with imported syringes, the range will become much richer. They also have very thin needles, for example for vaccinations. Don’t forget to also collect a collection of steel elastic wires for cleaning capillaries - number 4. Number 5 - my new gas stove came with a whole set of nozzles with different hole diameters. And finally, 6-end clamps for mounting multi-core electrical wires. A whole bunch of different diameters.
Scheme selection
Despite all the difficulties of assembling heating devices with your own hands or under the guidance of an experienced blogger from the video, making a gas heater is considered simple. Having correctly assessed your capabilities and needs, you can assemble a mobile or stationary heater.
A portable (mobile) gas heater will be an excellent solution for a summer house, garage, barn, greenhouse, during a picnic or fishing. Such designs are quickly assembled and connected to small-volume cylinders and are ergonomic.
Stationary type of gas heaters will require more effort to connect to a centralized mains or to standard 50-liter cylinders.
Important: all gas heaters are required to be equipped with a chimney to allow combustion products to escape. Regardless of the size and power of the unit, ventilation is always provided for safety in residential and non-residential premises.
The best solution for temporary heating
Now the scope of use of potbelly stoves is quite diverse:
- garage heating,
- cottage heating,
- heating of construction sites,
- heating of other rooms where centralized heating is impossible or not connected.
With its help you can both heat the room and cook food. A big plus is the ability to make a potbelly stove with your own hands from any old milk flask, barrel, gas cylinder, several pieces of sheet iron and pipe scraps.
It almost instantly gains temperature and quickly releases it into the surrounding space, but the latter fact has little effect if the room is sufficiently insulated.
Mobile design made from a gas burner
The most simple in design, portable, easy in design and operation, the model of a mobile unit is often used at a summer cottage and in camping conditions.
To make a compact device you will need:
- gas burner-primus or collet cylinder with shut-off valve,
- small sheet of tin,
- metal rivets,
- “kitchen” metal sieve.
Armed with this list, you can make an effective burner, the power of which will be sufficient to heat a garden house in the cool season. Alas, for winter the burner will heat up very little.
To assemble the mobile burner you will need the following tools:
- drill,
- small diameter drill
- riveter,
- metal scissors.
Experienced craftsmen suggest assembling a gas heater according to the following scheme.
- We take a small piece of tin and place a kitchen sieve on it, frame down.
- We draw a marker around the sieve and draw rectangular ears to the drawn circle, at a visually even distance and on four sides. Please note that one ear should be slightly longer than the other three.
- We cut out the resulting workpiece with metal scissors.
- We screw the cut out circle with ears to the burner using bolts.
- We bend the ears and check the degree of attachment of the sieve to the workpiece.
Why is a sieve needed, a reasonable question arises? During operation, it will act as a heat dissipator.
How can this model be made more effective and improved? Follow the recommendations and add a small piece of mesh to the list of materials.
- We cut out a circle with ears from tin, completely identical to the first one.
- In the round workpiece, taking into account a small indentation from the edge, we drill several holes.
- We prepare a narrow strip of mesh of small width.
- We attach the strip of mesh to the first and second circles using ears bent at right angles and rivets.
- We get a cylindrical shape, which better dissipates heat in the room.
How to make such a model? We invite you to watch the video review.
General recommendations for creating devices
In an effort to save on expenses, many owners, when choosing among heater options, are in no hurry to purchase ready-made factory models.
After all, if you have the desire and the appropriate skills, you can always construct a heating device on your own.
When choosing a DIY garage heater, many are guided by two parameters:
- The heating device should be easy to activate, quickly warming up the room.
- The device must have a simple design, devoid of complex parts and elements.
- Operation of the device must be carried out with minimal financial costs.
All these requirements are met by three options for the homemade heaters described below, which operate from different energy sources: gas, solid fuel and electricity.
The safety of the device is also important. Therefore, regardless of the heating method in the garage, it is necessary to equip a ventilation system
After all, a decrease in the amount of oxygen and the accumulation of combustion products poses a risk to human life.
Tabletop gas stove heater
How to assemble a tabletop heater from a gas stove yourself? We offer proven technology for creating a unit based on portable flat quadrangular tiles with a grid.
This type of heater is made by attaching a tile to a metal casing with a combustion chamber and a fan. This design is made independently according to preliminary calculations and diagrams.
We measure the required length and width of the future body, taking into account full compliance with the dimensions of the tiles. We fix the resulting casing with retaining bars-hooks. On one side, the bar is movable. To do this, a spring is attached and attached to the lifting lever. In the future, this will allow you to remove and put on the case as needed.
If the previous version did not provide for a ventilation system, then in this model it is part of the structure. Experienced craftsmen advise using available spare parts, for example, a fan from a window air conditioner will do. If the blades are too large, you can cut them to the required diameter. The fan is installed at the rear of the formed housing.
To create thrust, a metal combustion chamber is fixed inside the housing, and holes are made along its surface over the entire area. It is advisable that they be at a short distance from each other.
Various variations of this design are presented on the Internet, based on the functional tasks, you can choose the desired scheme. Note that the efficiency of the heater is quite noticeable, and the effectiveness of the device has been repeatedly proven by craftsmen and innovators. Unlike a gas burner, such a heater can be used in the winter season, raising the temperature to a comfortable level.
Making a boiler
From all of the above it follows that gas generator-type boilers are considered the most economical and high-quality elements of the heating system.
The main problem in purchasing and using such a boiler is the cost of this product. For example, the simplest model of such a boiler, which is manufactured by domestic companies, costs about $1,000.
If you choose imported manufacturers and improved models of such boilers, the price can increase 5 times. It follows from this that gas generator boilers cannot be called publicly available. But there is a more economical option for purchasing such a boiler. This method is a wood-burning boiler, made with your own hands. To make such a boiler, you need to use special drawings that are developed and posted on the Internet by craftsmen.
Gas-generating boilers developed by folk craftsmen have not only a low manufacturing price, but also other positive aspects. The use of a homemade boiler, manufactured according to ready-made drawings, provides for a significantly longer operating time of the boiler on one load of fuel into the combustion chamber. Due to the fact that in factory boilers, special nozzles are installed under the combustion chamber, through which air is supplied, pumped by forced systems, the combustion process of solid fuel is almost doubled. In addition, the direct dependence of such a boiler on the electrical network ensures that the system operates correctly only when the boiler is connected to the network. Homemade boilers are devoid of such elements, which allows them to work better and longer.
Some homemade boilers are equipped with two solid fuel combustion chambers. This allows the fuel to be burned in a consistent manner. When one chamber lights up, the fire in the other chamber automatically goes out. This helps achieve the highest efficiency with maximum fuel burning time in the boiler. Some design features of homemade boilers make it quite easy to control the process of fuel combustion in the boiler. This is achieved by correctly positioning the grates under the fuel bunker.
Almost all homemade boilers, drawings of which can be easily found on the Internet, burn all contaminated particles, such as essential oils, various resins and alcohol. This became possible due to the fact that in such boilers there is a separate zone of additional combustion. Contaminated air from the combustion chamber enters this zone. It is this air that contains polluted particles that are burned separately. It follows from this that a minimum amount of harmful particles enters the atmosphere, which can enter the heated room through the cracks and pores of the building material.
Solid fuel boiler drawing
A homemade wood-burning boiler is intended not only for the use of wood fuel. In such boilers you can use sawdust, peat briquettes or coal as fuel.
The use of such fuel materials involves the appearance of slag, which must be removed. This is necessary for the combustion process to occur correctly. In order to perform screwing, the boilers are equipped with a special hole under the combustion chamber. It is through this hole that you can insert a poker and destroy the slag crust. This hole is closed with a small door, which blocks the flow of excess air into the combustion chamber.
Drawings of homemade boilers are developed on the basis of finished factory products. The main difference is considered to be the changes made in design and production terms. The positive side of such boilers is the ability to heat a larger amount of air coolant with the same volume of the combustion chamber.
As practice shows, using air as a coolant allows you to create a more comfortable microclimate in a heated room. When using such a coolant, you can heat the air in the room in a short time. In addition, heat losses in such a heating system are minimal. Do not forget about the significant savings in money that must be spent on purchasing a special coolant. In addition, complete tightness of the heating system with air coolant is not necessary.
Pipe heater
Such heaters have different names, but in everyday life they are called thermal gas guns. Such devices have high power and release a lot of energy. They usually come complete with chimneys.
To make your own gas heat gun you will need the following materials:
- one pipe - diameter 180 mm and length 1 m,
- one pipe - diameter 80 mm and length 1 m,
- one pipe - length 30 cm and diameter 80 mm,
- mounting plates,
- Metal sheet,
- gas burner with piezo ignition,
- axial fan with round flange.
Tools:
- welding machine,
- roulette,
- spirit level
As with previous gas heater models, assembling the universal heat gun is quick and fairly easy. Let's start assembling according to the instructions.
- In a pipe with a diameter of 180 mm and a length of 1 m, drill two holes of different diameters opposite each other: 10 and 80 mm.
- We use the second pipe, 80 mm in diameter and 1 meter long, to make the combustion chamber. We take into account that it will require a piece of about 30 cm in length.
- We weld the mounting plates to the second pipe and make a hole on one side measuring 10 mm and insert it inside the first pipe.
- We cut out a plug from a metal sheet/plate to close the gap between the heat gun body and the combustion chamber.
- We weld the pipe intended for the combustion chamber to the inner casing.
- We proceed to welding the hot air outlet pipe to a hole with a diameter of 80 mm.
- We weld the plug.
- We check the rigidity of the installation of the gas burner in the chamber and pass a hose through 10 mm holes in two pipes.
- We install a fan heater in a heat gun, and in front we install a chimney on the chamber.
- For design mobility and ergonomics, legs are welded to the body.
Tip: instead of a pipe, innovators use used gas cylinders and fire extinguishers to make the main body.
Heating summer cottages, garages and greenhouses with self-produced gas heaters is effective and inexpensive, but how justified and safe? Such designs are recommended to be used as a temporary alternative to more modern and safer industrial production models. Factory models have several degrees of protection, are more functional and will provide residential and non-residential premises with constant and safe heating.
Addendum 2
Sometimes workers complain that the burner is not working or is not working properly.
Only working designs are posted here, no theoretical ones. This means that they did not notice or did not understand the principle of operation of the burners. Now I’ll try to explain using a mini-burner as an example. To do this, I will give a simplified diagram of this particular design. 1. Make sure that the incoming gas pressure is within the acceptable range of 0.2-4 kg/cm2. And the most working range is from 0.5 to 2.5 kg/cm2. And the diameter of the nozzle hole is 0.12 +/-0.02 mm. 2. The air intake holes are not closed. 3. In the picture. The diameter of the tube with the supplied gas-air mixture is 3.5 mm. And the central hole in the divider has a diameter of 3 mm. That is, 0.5 mm less. Therefore, part of the flow of the gas-air mixture diverges to the sides into small holes. The flow rate through these holes is less than the main flow. These small holes are precisely designed to ignite the main flow. And due to the low speed of the gas-air mixture, they burn stably and do not allow the flame of the main flow to be blown away. This is true for all burners of the type on this page with flame spreaders. 4. Based on the above, check whether there is still a 2mm gap between both parts of the burner head. If manufactured correctly according to the drawings, this gap will exist. Otherwise, you will observe only the central torch, without the side lights, which is easily blown away when the pressure of the gas entering the nozzle increases.
On the left is a non-working burner. On the right is how it should be. 5. And a few words about the position of the nozzle. The cut of the capillary from which the gas comes out must be positioned while the burner is running in the area opposite the air intake holes, or before these holes. And, of course, the tube with the capillary should not block the air holes.
Catalytic, ceramic and convector IR heaters
Every day the Internet offers more and more options for creating heating devices with your own hands. In parallel with sales of gas appliances, you can find diagrams and step-by-step analyzes of infrared, ceramic and catalytic heaters.
It is not so easy to make these models yourself, since the work involves taking into account more complex technological processes and requires the parallel installation of a good ventilation system. Experienced experts recommend purchasing a ready-made unit, which takes into account all technical standards and has the ability to automatically lock or turn off.
Big plus of the models:
- fire safety,
- high efficiency taking into account optimization of the combustion process,
- not such intense combustion of oxygen when compared with homemade units,
- visual appeal and maximum ergonomics for living spaces,
- ease.
Can we say that homemade gas heaters are a successful and profitable replacement for factory units and central heating? No, with all their advantages, homemade gas heaters can only be a temporary replacement and help in a summer cottage or garage.
Using scrap materials to arrange the work area
Let's consider options for making a kitchen apron with your own hands from scrap materials:
- A vintage tablecloth with a floral pattern will help you create a unique floral pattern. Such an apron will transform the kitchen, it will become cozy and comfortable.
- You can decorate your work area using photo wallpaper or a world map. In the latter case, a sheet of plywood is cut to the size of the apron and a card is glued onto it, then the surface is covered with a transparent layer of varnish so that high temperatures and humid air do not damage the paper. After the varnish has dried, attach the plywood to the base surface.
- Old broken dishes will help transform the design of the room. Pieces of ceramic are glued to the wall like mosaic tiles.
Installation rules
When installing the stove, you need to pay special attention to the following:
- The distance between the walls and the stove should be more than 5cm;
- The foundation must protrude beyond the edges of the stove by at least 10 cm;
- The height of the connector for the burner with an overlay should be 61.5-68cm, without an overlay - 47-55cm, width - 51.5-66.5 and 35-45cm.
Many craftsmen in the manufacture of gas furnaces do not stop there and constantly improve their products, equipping them with various devices.
There are homemade heaters with fully automated operation, equipped with special blowers that control the flow of warm air.
Necessary equipment
If you decide to connect a tabletop or built-in gas stove yourself, then first of all you need to prepare all the equipment. To complete the work you will need:
- flexible hose connecting the stove and the central gas pipe. Instead of a hose, you can use metal pipes, but in this situation the installation process will be more difficult and will require special skills. Since pipes can be connected to each other in the case of gas supply only by welding;
- a ball valve that allows you to shut off the gas supply, for example, in the event of a leak or other emergency, as well as for carrying out repair/preventative work;
In accordance with safety requirements, the tap must be made of brass and have a nickel coating.
- tools: adjustable wrench, screwdriver;
- gaskets and sealing tape for sealing threaded connections;
- dielectric coupling. The equipment is required if it is necessary to connect the stove to the electrical network, for example, if there is an electric ignition;
- soap solution and sponge to check the tightness of the system.
Choosing a flexible liner
What kind of hose is needed? The first thing you need to pay attention to when preparing the equipment necessary to complete the job is the choice of flexible gas supply. Flexible connection of a stove or oven can be done using:
Flexible connection of a stove or oven can be done using:
rubber reinforced hose. The eyeliner is made of vulcanized rubber. Reinforcement with textile thread gives the product additional strength. The hose is durable and has minimal cost. The equipment can operate in the temperature range from -35°C to +50°C. The average service life is 5 – 7 years;
Rubber gas hose with thread braid
rubber hose with metal braiding, which gives the product additional strength and durability. The equipment can operate properly for 8 – 10 years;
Rubber liner with durable metal braid
bellows hose made of metal. The product is distinguished by its high cost and large margin of safety, as well as a long period of use (over 10 years).
Metal gas line
To increase strength and service life, the bellows liner can be protected with a plastic braid.
Metal gas hose with additional protective braiding
When choosing eyeliner you should also consider:
- hose length. According to safety regulations, the hose must not be stretched. The maximum length of the gas hose is 1.5 m;
- type and size of thread. If the thread on the flexible connection does not match the size or type of thread on the gas pipe or gas stove, then the installation of additional equipment - adapters - will be required, which can reduce the level of tightness of the gas supply system.
Selecting a seal
The rules for connecting a new slab require sealing of threaded connections. To seal connections in the gas supply system, it is recommended to use:
FUM tape. The sealing material is laid in a thin film, which facilitates the method of application. Average service life – 10 – 12 years;
Sealing tape for threaded connections
Loctite 55 thread is a sealing material made from high-strength threads. In most cases, it is supplied in special plastic containers. The period of use of the material is no more than 10 years.
Sealing thread for gas system
Pipe system
The system itself consists of correctly selected and laid heating pipes, which connect your radiators and boiler to each other. There are two types of such pipeline laying systems: one-pipe and two-pipe.
When a heating system is being designed, a two-pipe supply scheme involves installing two pipes on each of the batteries, the so-called “supply and return”. Through one of them (supply), the coolant (water) enters the heating device, through the other (return), having already cooled, it returns to the boiler. The use of such a wiring diagram makes it possible to achieve the same degree of heating of the coolant in all radiators in the house. Two-pipe type wiring is divided into two main types:
- Connecting radiators in parallel-series (one closed ring).
- Using a collector, to which all radiators are connected with separate hoses (pipes).
The second type of connecting radiators makes it possible to regulate the temperature of each battery. But it also has a noticeable financial disadvantage, this is the need to install a large number of metal-plastic or other pipes for heating to provide connections to radiators. A single-pipe heating circuit made of metal-plastic pipes functions like this: the heated coolant (water) simply flows through the pipes from one radiator to another. Simply put, such a system is sequential, and this leads to a gradual cooling of the coolant along its route. This means that the last radiator in the chain will always be significantly cooler than the first battery. The main advantage of a single-pipe heating system made of metal-plastic pipes is the low cost of its arrangement.
Also very important is the degree of thermal insulation of your home. If you have taken all measures and insulated the walls, ceilings, floors, installed new good windows, and you have a modern, high-quality entrance door (doors). Then the heat loss of your heating system will be minimal and during the season, you will spend much less money than you planned.
heating elements
For heaters: types you will have to buy heating elements: 220 V electrical appliances with open heaters are extremely dangerous. Here, pardon the expression, you need to think first of all about your own skin and property, whether there is a formal ban or not. It’s easier with 12-volt devices: according to statistics, the degree of danger decreases in proportion to the square of the supply voltage ratio.
If you already have an electric fireplace, but it doesn’t heat well, it makes sense to replace a simple air heating element with a smooth surface (pos. 1 in the figure) with a finned one, pos. 2. The nature of convection will then change significantly (see below) and heating will improve when the power of the finned heating element is 80-85% of the smooth one.
Types of heating elements
A cartridge heating element in a stainless steel housing (item 3) can heat both water and oil in a tank made of any structural material. If you buy one, be sure to check that the kit includes gaskets made of oil-heat-gasoline-resistant rubber or silicone.
A copper water heating element for a boiler is equipped with a tube for a temperature sensor and a magnesium protector, pos. 4, which is good. But they can only heat water and only in a stainless steel or enameled tank. The heat capacity of oil is much less than that of water, and the body of a copper heating element in oil will soon burn out. The consequences are severe and fatal. If the tank is made of aluminum or ordinary structural steel, then electrocorrosion due to the presence of a contact potential difference between the metals will very quickly eat away the protector, and then eat through the body of the heating element.
T. called. dry heating elements (item 5), like cartridge ones, are capable of heating both oil and water without additional protective measures. In addition, their heating element can be changed without opening the tank and without draining the liquid from there. There is only one drawback - they are very expensive.
Oven
Gas stove ovens are:
- gas;
- electrical;
- combined (with electric grill).
The optimal choice of the last two types of ovens, since they distribute heat evenly. However, with this choice, you must definitely consult with an electrician to see if the wiring can withstand the resulting load.
Gas ovens can be of 2 types:
- without convection;
- with forced air circulation.
The best choice is a gas oven with forced air circulation, since in this case the likelihood of cooking food that is not cooked through or that is burnt on one side is minimal.
Oven
We talked about how a gas stove works, now we will analyze in detail the operation of the oven from turning it on until the end of cooking. Experts in the operation of gas equipment have developed several recommendations for users that must be followed when using the oven.
- During cooking, there is only a baking tray inside for collecting fat and a grid for storing food - all other kitchen utensils are stored in a special compartment located at the bottom of the stove.
- Before starting cooking, preheat the oven for several minutes at the maximum heat level, and then set the desired level using the rotary control.
- When a dish is being prepared, you should not open the door often - the temperature inside the oven immediately drops, and you can observe the cooking through the glass.
- After cooking, the gas supply is turned off, the regulator is placed in a vertical position, and the oven begins to cool.
You should take out the hot baking sheet using special oven mitts that protect your hands from burns.
How to light a burner correctly
Use the regulator to set the heating mode (usually 9 or 10 on the scale), open the door. At the very bottom in the middle there is a special hole to which a match or a special lighter is placed. There is a red button on the control panel - you must press it to open the gas supply. When the burner lights up, you need to hold the button for a few seconds to heat up the thermocouple that controls the solenoid valve. If you immediately remove your finger from the button, the flame will go out; all actions must be started all over again.
Internal temperature
Setting the desired temperature is very simple - just turn the knob and set the arrow embossed on it opposite the selected mode. How do you know if the actual temperature inside matches the selected cooking mode? To do this, experienced cooks pour a little clean flour onto a baking sheet and watch through the glass to see how its color changes:
- if it turns brown, the temperature is about 230 0C;
- golden color - no more than 180 0C;
- when the color does not change over time - about 100 degrees.
Modern models have a thermometer on the glass, but you also need to know the secrets of determining temperature using grandma’s method - everything can come in handy in life.
Cooking with taste
Previously, in order for a fragrant crust to appear on a carcass or meat, the housewife would often open the door and pour the secreted fat over the dish, but for modern gas stoves this is a long-forgotten technology. Many oven models are equipped with special fans that force hot air to move inside the product, distributing the heat evenly: there is no need to grease or turn over the carcass of the roasted bird, it will be fried equally on all sides.
To cook meat in your apartment as if it were over a campfire, just experiment with setting up the grill. and you can surprise your guests with the aroma of dishes cooked over an open fire in the field. You can add a little liquid smoke from a bottle purchased at a nearby supermarket for flavor.
Oven
The following types of ovens are distinguished:
Gas
Gas stoves cook quickly, but it is difficult to adjust the temperature in them. So, setting the temperature to 50 ℃ (useful for drying vegetables) is very difficult. However, low energy costs (especially if you install a gas meter) and ease of operation often compensate for these features.
They differ from each other in the location and number of heaters. In inexpensive models, the burner is located only at the bottom, but in more expensive ones there is also an upper burner - a grill. Some devices are equipped with a fan that mixes the air and prevents the formation of “cold” zones, which means the dish is baked evenly.
Electrical
Using this option is much more convenient due to more precise oven settings. Those who love to bake should take a special look at these units. Disadvantages: energy costs, long warm-up and cool-down times.
Devices of the simplest modifications have two heating elements - at the top and at the bottom. More complex models already have four heaters: more side heaters are added. Convection allows you to maintain the same temperature throughout the oven and is present in devices of medium and high price levels.
Every housewife should decide which is better, focusing on her own feelings: some are more accustomed to cooking in a gas oven, while others are more comfortable in an electric cabinet.
Installing a gas stove in an apartment: tips and installation instructions
Propane gas is a dangerous, flammable substance, therefore all work related to the installation of equipment operating on it must be carried out by qualified specialists, although you can install a gas stove yourself, but in compliance with all safety standards, which we will talk to you about today. So, the topic of today’s article is installing a gas stove in an apartment.
Installing a gas stove in an apartment
Preparation
When sketching drawings of a gas furnace, it is necessary to indicate the exact parameters of each element.
- At the installation site, prepare a level base and cover it with a fire-resistant layer.
- Lay fireclay bricks on top in two rows.
- Walls located less than one meter from the stove and the ceiling must be protected with non-combustible material.
- Most stoves heated by gas have almost the same design, so their assembly and installation is also identical.
It is not difficult to assemble it yourself; the main thing is to properly prepare the room before doing so, following the recommendations of specialists and observing safety rules.
Gas pipes in the kitchen: is it possible to redo the supply to the stove?
This article is an attempt to clearly explain what a resident of an apartment building can do with his own hands with the internal gas pipeline in his apartment. I will pay attention to the restrictions set out in the regulatory documentation and talk about my own practical experience regarding how and with what you can move the gas pipe in the kitchen. So, let's go.
The gas distribution makes it difficult to move the stove and hang cabinets. The desire to remake it is quite natural.
How to properly connect a muffle furnace to an energy source
If you have no experience working with electrical devices, it is better to contact a professional electrician. To connect the device to the network you must purchase:
- thermostat;
- large terminal block made of heat-resistant plastic;
- small terminal blocks made of heat-resistant plastic for splicing wires;
- contactor (electromagnetic starter);
- two-core electrical wire;
- electrical plug;
- standard casing for electrical panel.
For this oven, a single-channel thermostat M-1-K was selected, which regulates the temperature of the working chamber up to 1300 degrees. The device is capable of working according to a complex schedule; it is used to set the heating time and temperature.
Reference. The cross-section of the nichrome wire and its length, the diameter of the spiral turn, the cross-section of the connecting wires and other parameters of the electrical circuit are calculated from reference books and selected in advance.
The element has 7 connectors for connection (two terminals for power wires, two for connecting a thermocouple, three for a relay). The device is controlled by four buttons. When the thermostat is turned on, the indicator light is on. The device comes with two brackets for mounting in a panel and detailed connection instructions.
Block installation
The block is installed in the following order.
- The contacts of the thermocouple and the spiral are insulated and connected with terminal blocks to two-core wires.
- A plug is connected to the power cord.
- The thermostat, contactor and large terminal block are mounted in the panel.
- A thermocouple, a muffle spiral, and a power wire with a plug are connected to the thermostat via a contactor and terminal block.
An electric muffle furnace must be grounded.
Increased gas pressure under the throat
A significant obstacle to speeding up the operation of blast furnaces is the insufficient gas permeability of the charge materials column. As the amount of blast increases, the speed and lifting force of the gases in the blast furnace increases. Upon reaching certain speeds, the lifting force of the gases can balance the column of charge materials, and their descent stops.
In order to maintain a smooth flow of charge materials and at the same time speed up the furnace progress, it is necessary to reduce the speed of movement of the furnace gases, maintaining and even increasing the amount of blown air. This is achieved by increasing the gas pressure in the furnace; at the same time, its volume decreases, and consequently, the speed of movement decreases, which makes it possible to increase the amount of blown air.
An increase in pressure is achieved by reducing the cross-section of the gas pipeline by installing a throttling device. This measure can significantly reduce dust removal, which also improves the performance of the furnace.
Switching the furnace to operate with increased gas pressure under the top significantly changes the distribution of gas flows in the furnace; for example, the peripheral flow of gases increases. Peripheral loading allows better use of the reducing power of gases. However, it is necessary to ensure good gas treatment of the central zones of the furnace, that is, materials located along the axis of the furnace must have sufficient gas permeability. Thus, when the gas pressure at the top increases, the preparation of the charge should be improved.
An increase in pressure increases the density of gases, which ensures better processing of charge materials and an increase in the rate of oxide reduction, and the higher the pressure, the greater this effect. Therefore, transferring furnaces to work with gas pressures of 176 - 245 kN/m2 (1.8 - 2.5 atm) is the immediate task for blast furnace workers. At the advanced ones, the Cherepovets Metallurgical Plant, etc.), the gas pressure at the top has already reached 196 kN/m2 (2.0 at).
Increasing the gas pressure under the top made it possible to reduce coke consumption by 1 - 3% and increase productivity by 5 - 10%. The results obtained depend on the smelting conditions - pressure, quality of raw materials, fuel, etc. The practice of operating blast furnaces confirms the advisability of further increasing the pressure under the top.
As the gas pressure in the working space of the furnace increases, it is necessary to further increase the reliability and durability of the structural components and equipment of the blast furnace - tuyere hoses, atmospheric valves, charging apparatus, air and gas pipelines. Thus, the durability of filling devices is currently still insufficient and does not yet exceed 10–15 months.
At the same time, the question arises about using the energy of compressed gases, which, in particular, will reduce the cost of compressing the blast, for example, as a result of installing gas turbines in the place of gas throttling.
Stages of work
Each stage requires special attention, from preparing the gas cylinder to decorating the finished structure. A pre-prepared drawing will help you make the necessary device as quickly as possible. To speed up the process, it is necessary to prepare all materials and equipment in advance.
Required Tools
- grinder for cutting;
- drill for preparing holes;
- welding to connect component elements;
- bolts for fastening individual components.
To prepare the container and mark it, you may need a hammer, marker or an adjustable wrench. Some accessories may be replaced, but these tools are sufficient for quality preparation and assembly.
How to cut a balloon correctly
You should proceed to cutting after it has been completely cleared of gas residues. This must be done according to pre-made marks. The work is carried out carefully so that the edges are as smooth as possible. After cutting, it is necessary to clean and polish.
Making Tips
To make a practical and reliable thing, you need to think through the concept in advance and draw up a drawing. The diagram is important not only during manufacturing, but also when calculating the necessary materials. To ensure safety, you should use personal protective equipment and follow proper techniques when working with explosive objects.
Stationary structures, traveling options - everything can be made with a little effort and spending a little time.
