How to Increase the Efficiency of a Brick Gas Furnace?
Despite technological advances, in real life we often see this symbiosis of old and new technologies. I mean a regular brick stove, and gas equipment.
It all looks pretty basic. Built-in gas burner with minimal protection against flame failure (or flame extinction). After the flame is lit, a special metal plate, expanding from the heat, holds the valve in the open position. If the flame goes out, the plate cools and releases the valve, it automatically shuts off the gas supply.
At one time, when people used gas without thinking about the number of cubes spent, such a gas burner for a brick oven suited. The burner has been working for a long time, without shutting off, and heated the room. Now, such a burner for half a day has screwed more than 20 cc on the counter, and involuntarily thought that something needs to be changed.
The oven thermostat does not regulate the flame
This effect is often complained about by housewives who are not very good at understanding how the oven thermostat works. If you have a stove with a thermostat, the flame may not change immediately when you change the position of the regulator. The thermostat works this way: first, while the oven is cold, the gas is on full power, no matter how the motor is set. As the oven heats to the desired temperature (which is set on the regulator), the valve gradually closes, the flame decreases.
But two other malfunctions may be related to the thermostat. First, after heating the oven, the flame can go out. Second, the flame can burn too hard, even though the oven is already hot. Both of these problems are caused by improper adjustment of the oven burner low flow screw (fig. 3. A).
Figure 3. Removed faucet handles and the front panel underneath these faucets.
This screw needs to be turned out a little. Light the oven, close it. Set the regulator to 140 degrees. Wait 10 minutes. Now, by adjusting the screw, we have to obtain that the flame is small (tongues about 4 mm), but burns steadily, does not go out. This is usually easy to do. But sometimes even with the screw turned all the way down, the flame is too high. The thing is that there is a small hole in the screw, which prevents the gas supply from completely shutting off even when the screw is screwed all the way in. I still do not understand why I need this hole. But the fact is. If the flame can not be reduced to the desired level, the screw must be unscrewed completely and replaced by a screw with a smaller hole, or glue the hole at all with Poxypol (it is absolutely unnecessary). Then put the screw back in and adjust the flame.
All the above is valid for the oven with thermostat. Burner with a tap is adjusted similarly to the table burners. You can tell the difference between a thermostat and a faucet very easily. On the scale of the thermostat are written temperature values. On the scale of the faucet are simply numbers.
Timely clean the burners of the gas stove from the fouling, they are easy enough to remove, they can be disassembled and clean all the parts separately. Burner tops (lids) can be cleaned in a soapy solution and rubbed with a sponge or toothbrush if they are very dirty.
Remove the grills and detach the breakers. Then you need to remove the burner, inside which you can find the nozzle in the form of a small hole. Use paper clips or wire to clean the holes. Next, return the grids and burners to where they should be.
How to increase the power of the gas burner and improve the flame on the stove: an overview of popular ways
In this article, we will consider what the burning temperature of gas in the gas stove, what it depends on and how to determine it. We also help you to choose the optimal cooking temperature for different dishes.
How to adjust the gas burner?
Adjustment of the gas boiler burner flame is recommended with the help of a gas analyzer. It registers indicators of air, which is involved in the combustion process: CO concentration, oxygen level, excess air ratio. Concentration of CO should not exceed 50 ppm, oxygen is normally in the range of 3,6-5,3%. Less oxygen will lead to the fact that the fuel will not burn completely, more. to a high concentration of CO2. An excess of air can cause an explosion, and a lack of air can lead to incomplete combustion, soot, soot and low efficiency.
The intensity of the flame can be observed through the sight hole. the orange color is too big, you can turn it down until it is almost invisible and has a bluish hue. This fire provides the optimal mode of operation of the gas boiler. If you reduce the flame even further, it becomes completely invisible and then goes out.
Regulation of the starting fuel supply works only at the moment of ignition and does not affect the efficiency. But if you want it can also be adjusted: you need to gradually reduce the starting supply, turning on the burner until it stops lighting up; then you need to increase the starting supply, turning the regulator in the opposite direction. Adjustment ends with a check to see if the burner is ignited.
If the flame burns with noise, reduce it with the regulator.

Electrical equipment does not work
All the equipment
If all the electrical equipment on the stove does not work, it is most likely because there is a malfunction in the electricity supply. There may be no contact in the outlet, the plug or wire may be damaged, the wiring inside the stove may be broken. First you need to check the serviceability of the socket by plugging in another electrical appliance. If the socket is fine, then the stove needs to be disassembled. Use a tester to check the serviceability of the wiring. If the stove has mounting contacts, then check the conductivity between the plug contact and the mounting contact. If there are no such contacts, you have to cut the wire, check it, then connect it back.

Gas stoves appeal to consumers because of their ease of use and the cheapness of the fuel. However, we should not forget that in the operation of such a device, it is necessary to observe certain safety rules. You can not turn on the gas, if the gas stove does not work well, otherwise it will lead to dire consequences. If a breakdown is detected, it is necessary to call a specialist who can fix it.
Repairing the gas stove with your own hands
Repair of gas stove with your own hands is prohibited by law True, criminal liability is not yet provided, if an accident happens, foresee trouble. In the city-hero of Volgograd, a smart guy put the combustion products of a water heater in the vent. Four people died. Authorities classified the case under the article causing death by negligence. Masters of the gas service are empowered to make equipment replacement, to perform service work. Topical, starting with sub lines, ending with a switch to another type of fuel. Here are a couple of recommendations below, not a user manual, just general techniques.
Types of burners
By far the most common option is a propane burner. If we classify by the type of fuel used, we can still distinguish liquid varieties, as well as those running on a combustible mixture.
As fuel in the liquid burner is used oil. This type of device is used much less often than its propane counterpart, since the effectiveness occurs only in the temperature range of 10 to 15 degrees Celsius.
The difference between the burner, which operates on a combustible mixture, is that in addition to gas, air or oxygen is fed into the working area.
It is possible to classify burners by the number of working nozzles. In some models there are up to 4 burners. Such a product allows you to significantly extend the functionality and at the same time to heat a larger surface area. The disadvantage of increased number of nozzles is higher fuel consumption. Therefore, it is worth using such devices on objects with a large area.
Burners can also be classified by the presence of reducer in the construction. This device is responsible for changing the intensity of fuel mixture supply into the working area. That is, if there is a reducer in the burner, you can adjust the power of the flame. The cost of devices without a reducer will be lower.
Burners also differ in terms of fuel ignition. Most modern devices have a piezo ignition function, making it easier and safer to use the device. But there are still variants that require using matches or a lighter to ignite the fuel.
The burner can be equipped with a standard or shortened gas tube. This element can be straight or bent. These parameters are selected in accordance with the working tasks that are to be carried out.
How to fix the problem
@kvobzor.ru If the nozzles are dirty, it is enough to rinse the stove well, preliminarily shut off the gas supply and wait until the appliance has completely cooled down:
GAS STOVE BURNERS BURNING LOW? FIX IT YOURSELF How to Fix Low Flame on Gas Stove
- Remove the grate and flame spreaders, if necessary remove from them sticky or burnt pieces of food, then immerse in a warm solution of detergent and leave for 15-20 minutes.
- Clean the clogged nozzle hole with a long needle or a piece of metal wire of suitable diameter. All actions must be carried out without pressure, delicately.
- Rinse all the elements under running water, dry them and install them in their places without tilting. Check that all the protrusions are aligned.
If cleaning did not bring results, you should pay attention to the diameter of the nozzle, it is shown in millimeters by a special marking and must match the size of the nozzle. If there are any irregularities, the nozzles can be replaced carefully. It is important to screw them in strictly perpendicular to the plate surface.
How to Fix Low Flame on Gas Stove
The air supply is regulated by air discs and the locking pin has to be slightly re-tightened (details location can be found in the instruction manual of the device). If the operation is carried out correctly, the flame burns quietly and its height does not exceed 25 mm.
If you find deformation of old parts of the stove, replace them with new ones, it is dangerous to fix and repair the elements of gas equipment for further operation.
