Gas equipment provides comfort while cooking and is quite easy to operate. And the cost of the energy carrier is affordable. Where there is a centralized gas supply, there are no difficulties with fuel supply. In small settlements, in dacha cooperatives, there are no central networks, the population uses cylinders to supply gas appliances.
The quality of bottled gas is somewhat different from that which is supplied centrally, and the owners of the stoves may notice that the burners do not work correctly. Understanding why the gas stove smokes, it is worth considering that not all malfunctions can be eliminated on your own. In most cases, you will need the help of a qualified professional.
In this article, we'll talk about the main causes of soot and options for eliminating damage. We also note in which cases you should immediately contact a specialist.

The main causes of soot
The gas stove works properly if the flame in the burner is naturally blue, without any red and / or yellow tint. When multi-colored tongues appear in the flame, the gas is supplied unevenly, then such work cannot be called correct. A reddish tint of the flame indicates that the fuel does not burn completely or there is not enough air to burn the gas.
Red flames often precede soot.
The reason for a similarly unpleasant phenomenon is considered:
- poor gas quality;
- high / low blood pressure.
When the gas mixture contains too much mercaptan sulfur, thick, black smoke appears, the particles of which settle on the dishes, the walls of the room.
Incorrect operation of the burners, the presence of soot during the combustion process may indicate low gas quality, low or high pressure in the system.
A similar situation is observed when the stove is connected to a low-quality cylinder with a low gas content. In some cases, soot appears when there is a malfunction of the burner itself.
Let's consider the main reasons in more detail.
Reason # 1 - poor fuel quality
Understanding why soot appears from a working gas stove, it is important to know that the cylinders are refueled gas mixture. When there is a high sulfur content in the composition, soot appears.
If you are absolutely sure that low-quality fuel has become the cause of soot, you can file a complaint with Rospotrebnadzor and other organizations of a similar profile.
Together with the application, you will need to provide:
- receipt issued when refueling the cylinder;
- the tank itself (cylinder) with low-quality fuel for the examination.
Often, such incidents are resolved peacefully in favor of gas consumers. You do not know what to do when a gas stove, powered by a cylinder, smokes and what measures can be taken immediately?
Then remember the simple algorithm:
- try to move the cylinder or gas oven to another place;
- if you have friends who use the services of the same organization that refills cylinders, check if their gas stove smokes;
- contact the fuel supplier with a request to explain the increased sulfur content in the gas mixture;
- in the absence of contact with the organization that refills the cylinders, write a complaint with a request to restore justice, to compensate for the cost of property damaged by soot.
When starting an investigation with your fuel supplier, make sure that the problem is in the quality of the gas. We also recommend that you familiarize yourself with the requirements for cylinders when refueling and filling rates.
The actions of unscrupulous suppliers do not pose a danger to the health of users of bottled gas, but creates a lot of inconvenience during operation
In addition to problems with gas supplies, soot is often caused by the need to adjust equipment and eliminate malfunctions.
Reason # 2 - Incorrect cooker settings
Understanding why a household gas stove smokes, connected to a propane tank, it is important to assess the pressure level in the system. It depends not only on the quality of the cylinder, but also on the features of the burner. To deal with the problem, it is important to know the device of the latter.
The hotplate consists of the following elements:
- Divider - designed to distribute fuel evenly around the entire perimeter of the burner. In appearance, the divider resembles a sleeve that is cut along the contour.
- Divider cover provides the desired diameter, looks like a round lid made of stainless steel, located on the top of the divider.
- Spark plug - an element of modern models of gas stoves. A spark is a signal to start work, gas is ignited from it. The candle is located on the side of the divider, next to it there is a temperature sensor, which ensures the safe operation of the stove. If the fire is extinguished, a command is transmitted to a special electromechanical device,
- Jet located under the divider, looks like a small bolt with a through axial hole. The nozzle is responsible for the uniform supply of fuel and regulates the pressure.
The appearance of soot, incorrect operation of the gas stove - all this is often associated with the installed nozzle, or rather, with too large a hole in it.
When disassembling the burner, pay attention to the nozzle. The hole in it should not exceed 1 mm, otherwise soot will form when the gas burns
Uneven fuel delivery may be due to blockages. To clean the nozzle, you need to carefully insert a thin wire into the hole, twist it between your fingers. It is not recommended to press, pick the jet. This can lead to an enlargement of the hole, the appearance of soot.
If there is dirt, remember to clean the rest of the parts as well, as soot can come from the burning of deposits that have accumulated on the burner surfaces. Rub all the elements well with an old toothbrush soaked in detergent. Then rinse the parts under running water and dry well. Only then proceed with the assembly of the gas stove.
Reason # 3 - insufficient air volume
Insufficient air quantity, which is supplied to the burner, will lead to the appearance of soot even if all other elements are in good working order. To adjust the air discs, it is worth unscrewing the locking screw, proceed very carefully.
The air discs are adjusted very carefully. At the end of the work, the flame should burn evenly, during the operation of the burner there should be no extraneous sounds
After completing the adjustment of the operation of the air discs, it is necessary to immediately check the quality of the gas stove.
When the burner is turned on, the gas must burn out without extraneous sounds, hum. Flames should not be more than 2.5 cm in height. If the adjustment does not help, it is worth returning the air discs to their original position.
When should you replace a nozzle?
Modern gas stoves, for the most part, are designed for a centralized gas supply. Methane is used in the central networks, system pressure differs from the pressure in the cylinder, therefore a slightly larger diameter hole in the nozzle is required. When using bottled gas, propane is used to provide domestic needs, therefore, a jet with a smaller opening is required.
In the basic configuration, injectors are always used, designed to supply fuel through centralized lines. The complete set of modern models may include a spare jet designed for bottled gas. Also, for the use of cylinders, it is additionally necessary to replace gas reducer.
When trying to get rid of the cause of the appearance of soot on the burner of a household gas stove, it is important to purchase a jet that corresponds to the brand of the household appliance. Otherwise, the replacement of the part will not bring the expected result.
Correct selection of a nozzle, competent installation ensures the smooth operation of the gas stove. If there are installation errors, the fuel will be supplied unevenly
There is no nozzle on older models of gas stoves. However, they are equipped with a mechanism that allows you to adjust the rate of fuel intake. You need to configure it correctly. Adjustment is carried out by turning the valve with which the gas cylinder is equipped. Without unscrewing the valve to the end, it is easy to reduce the gas pressure in the system, to minimize the likelihood of soot.
In some situations, soot appears when the oven is turned on. It is likely that the replacement of the nozzle is necessary here as well. In most gas stoves, the jet is located behind the left side of the oven chamber, into which the arc-curved burner is inserted. To replace the nozzle, unscrew the screws, remove the burner, find and replace the part.
With prolonged operation of the gas appliance, the jet could stick to the burner nozzle. In such a case, it is necessary to lubricate it with a special compound, wait a few minutes.
When the jet is deformed, the fuel flows to the burner unevenly, soot may appear, gas accumulates in the device, which is dangerous. To replace the nozzle, you need to look at the brand of the gas stove, select the appropriate accessories.
It is important to remember that gas equipment is potentially dangerous, therefore, in case of any breakdowns, it is advisable to invite specialists from the gas company with which you have contract signed for service.
Conclusions and useful video on the topic
The soot that appears when using a gas stove causes a lot of trouble. The reasons for this behavior of the burner can be different, but most often, they are associated with the incorrect size of the nozzle orifice. The video shows how to quickly replace the jet, to ensure the normal operation of the gas appliance:
When the gas stove smokes, it is necessary to start diagnostics by checking the correspondence of the injector to the type of fuel. If everything is in order here, you should pay attention to the quality of the fuel. It is recommended to fill cylinders only in trusted organizations. In some cases, the appearance of soot is associated with the presence of a malfunction. To find a breakdown, to correctly eliminate it, you should invite a professional.
