Why does a gas stove with a propane tank smoke: main breakdowns and recommendations for elimination

How to clean nozzles?

One reason is clogged injectors. Because of this, the gas pressure changes and the stove will smoke. Let's look at how to clean the nozzles. For any work with gas stoves, the first step is to turn off the gas supply. You should also check if the stove is hot.

To clean the blockage, you will need to dismantle the divider and its cover. There will be a small hole inside.With a sewing needle, this hole is carefully cleaned, no effort is needed. It will be enough to rotate the tip of the needle in the hole.

If there is dirt, then it does not hurt to clean the divider with a cover. To do this, you can use a toothbrush, dishwashing gel, warm water. Do not clean with a nail or wire. Modern stoves are made of delicate materials and will not withstand such an act of vandalism. Next, the burner is wiped dry, dried. Then (about half an hour later) set in place.

Design features of gas devices

Some gas stoves of certain European brands are noisy by definition. This is due to their design features and the introduction of technologies aimed at saving resources. These technologies save gas.

For the most efficient gas consumption in such a stove, the turbo effect is used. Some modern burners have two or three rows of perforations (unlike older devices), which results in faster heating. But because of this, additional background noise may also appear.

Those. the intensity of combustion increases, but because of all the innovations, the burners begin to make a lot of noise. In addition, on new stoves, the burners suck in air directly under the flame, which is why characteristic sounds are heard (whistling, hissing, tapping, etc.).

On old tiles, this process took place inside the burners, so it was barely audible. If the noise is too loud, you can try to reduce it by adding or decreasing throttle.

When buying modern gas stoves, you need to be prepared for the fact that you won’t be able to completely get rid of the noise of the burners.

Also, the appearance of a noise background during the operation of a gas stove may be due to the installation of not quite suitable parts. New plate kits often contain additional items that can be mistaken for spare parts, but they are not.

In most cases, such parts are designed for different gas pressures. But only an employee of the GorGaz department, with whom the owner of residential property has entered into an agreement for the maintenance of gas units and the supply of blue fuel, should change parts of the gas stove for new suitable elements.

If an ordinary gas stove was moved from an apartment with main gas and installed in the country, connected to a cylinder, and it began to make noise during operation, then in most cases this is due to inappropriate jets.

Jets are responsible for supplying gas in the right volume at a certain pressure. The fact is that the gas in the main pipes and cylinders has a different composition, because the nozzles differ in structure and size.

Why does a gas stove smoke? What to do?

The flame on a stable gas burner looks uniformly blue. If something is wrong, then you will see the red-yellow color of the flames. This indicates incomplete combustion of gas or lack of oxygen. The yellow-red flame is the culprit for the appearance of soot.

The gas burner consists of a top cover, a flame diffuser, a nozzle, some gas stoves are equipped with electric ignition and almost all modern models have a gas control system that activates and shuts off the gas in the event of an extinct flame.

A gas stove can start to smoke for a number of reasons:

• The cleaning nozzle is clogged.What to do? As a rule, it is enough to remove the cover, the flame diffuser, clean the hole, and, if necessary, soak the flame diffuser in water. The fact is that the flame divider could also become clogged. After you wipe all the components dry, you can put them back.
• Deformation of the flame diffuser due to long-term operation. Despite the fact that the part is extremely resistant to moisture, fire and other things, the flame diffuser fails over a long time. It is enough to replace it and the problem will be solved.
• An extremely rare case in the case of main gas supply - but indeed, in some houses, the quality of gas may vary.
• A more frequent case of smoking a gas stove is found in summer cottages where there is no central gas supply and gas cylinders are used that are connected to a gas stove. If the stove smokes, it means that either the gas pressure in the cylinder is too high or the gas itself is of poor quality and contains an excess of sulfur impurities.

So, if you have tried all the above methods and for some reason they did not suit you, then the only thing left is to unscrew the nozzles and clean it. The nozzle is something like a small bolt with six edges, with a hole in the middle. Gas is supplied through the nozzles and, accordingly, if a small hole in the middle is clogged with soot, troubles and malfunctions begin. Sometimes it happens that the injectors (the diameter of the hole itself) do not fit the pressure of the main gas (or compressed gas in the cylinder), which leads to a quick failure. On various forums, you can find a lot of advice on how to change the diameter of the hole for the gas outlet on the nozzle.Never follow these tips! This is deadly! If you try to solder the hole on the nozzle yourself, and then make a hole of the “required diameter” - any slightest deviation from the strictly vertical one - can lead to an explosion, as the gas will go past the burner and the system that shuts off the gas in case of flame out, simply will not have time work.

Common causes that you can solve yourself

When choosing kitchen equipment, most women settle for the best option, a gas oven. It is characterized by ease of operation and maintenance, a wide range of possibilities and the most accurate settings. Despite the many advantages of use, there is a common problem during operation: the oven goes out after a short time after arson. What could be causing this problem?

There are several main reasons:

• Lack of oxygen in the gas furnace;
• Shutting off the gas supply valve;
• Fire sensor malfunctions;
• Pressure drop in the pipeline;
• Incorrect operation of the burner due to its contamination;
• Incorrect burner setting after removal and cleaning.

These problems are easily fixed on their own, without calling a wizard: no special skills and a lot of time are required.

Solving the problem with your own hands:

• The lack of incoming oxygen is eliminated by igniting the oven with the door open.
• The valve responsible for the gas supply is accidentally closed during cleaning, after which they forget to open it. To fix this problem, you need to open the valve.
• Additional flame detectors are provided to ensure fire safety. They monitor the temperature in the oven. In the absence of heating, the sensor turns off the gas supply. To solve such problems, the switch-on knob is held longer than usual and during heating, the maximum temperature is turned on. The problem is typical for ovens equipped with gas compressed in special cylinders. The sensor does not heat up due to the slow rise in temperature and turns off. To fix the problem, the cylinder is refueled or a new one is bought.
• The ingress of fat and pieces of food into the burner provokes its failure. Clogging is visible to the naked eye: the burner is ignited intermittently, in some areas there is no fire. To solve the problem, the contaminated part is removed and thoroughly cleaned, after which it is returned to its place and the oven continues to be used.
• After cleaning, the burner is often incorrectly installed. For troubleshooting, the burner must be removed and installed correctly.

Causes of soot

As you know, the principle of operation of gas stoves is based on the process of burning gas, or rather, its mixture with oxygen. A flame from a spark occurs only when the fuel reacts with oxygen from the air, while the hydrocarbons that make up the gas (methane with an admixture of ethane, propane and butane - in the line, propane - in cylinders) turn into carbon dioxide ( CO2) and water vapor (H2O). The optimal ratio of gas and air is 1 to 10, then the gas burns completely at the maximum temperature, and the color of the flame is blue, sometimes with purple splashes. All tongues of fire are the same height.

When less air is supplied than required, the fuel does not burn completely, and the reaction produces carbon monoxide (CO) and hydrogen (H2). The temperature of the flame in this case is lower, the color is yellow with flashes of red, and the flames are of different heights and leave black streaks of soot on the kitchen utensils. But it is necessary to fix the problem not in order to easily wash the dishes after cooking, but for the safety of the users themselves.

Since stoves can use a central or local gas source, the causes of soot are different.

Main gas supply

If all the burners of the stove connected to the gas main are smoked, the reasons may be as follows.

1. The gas pressure that is supplied to the burners is not adjusted. The stove is designed to burn a certain volume of gas per unit of time. If the flow is too strong, the gas does not have time to burn without residue.
2. The air flow that mixes with the fuel is not adjusted. The air supply in some stoves is also subject to adjustment. If the volume of oxygen is below normal, hydrocarbons in the gas-air mixture do not burn out.
3. The gas in the line contains foreign impurities. When sulfur gets into the fuel, soot deposits appear during its combustion. However, this option is unlikely - the quality of gas is monitored very carefully.

balloon gas

If a stove connected to a liquefied gas cylinder smokes, then:

• the gas pressure exceeds the recommended values;
• there are too many impurities in the fuel;
• Incorrect nozzles are installed in the burners.

The pressure of the gas that enters the line is lower than in the case of a cylinder, where the mixture is compressed to a liquid state. Without adjustment, the pressure may be too strong.In addition, often gas in cylinders comes across of poor quality, since there are many suppliers of such fuel, and among them there are unscrupulous or careless companies.

But most often on the stove, which is connected to the cylinder, the nozzles (jets) do not change. The diameter of the hole through which fuel enters the burner is designed for a certain pressure, while main and liquefied gas require different throughputs: the first needs a larger hole, the second needs a smaller one. It should be remembered that when transporting the stove from the dacha to the apartment and switching from bottled gas to the central jets, you will also need to change it, otherwise the performance of the burners will drop.

Common malfunctions of burners

In addition to the excess amount of gas that goes to the burners, problems with parts of the burners themselves can be the causes of soot. The following breakdowns are common:

• jet hole clogging;
• deformation of the divider (slotted bushings through which the gas is evenly distributed);
• contamination of the holes in the cover of the flame diffuser.

These reasons are worth thinking about when smoking individual burners. But you need to check them, even if soot forms over all burners.

Tales about gas and gas stoves

There are many tales about gas and gas stoves. It is said that it is the stoves that cause explosions in houses in the event of a gas leak. Upon closer examination, it turns out that this is due to their misuse by users.

Modern models of equipment are equipped with security systems that shut off the gas supply when the fire is attenuated. At the same time, it accumulates in a minimal amount - such a volume cannot lead to an explosion.

Some housewives talk about the inconvenience of using gas stoves. To ensure that food cooks evenly, they constantly monitor the temperature in the oven and the amount of fire under the cookware. The other part of the hostesses, on the contrary, like it. With self-regulation of the fuel supply, a crispy crust is obtained on dishes, which is difficult to do on electric stoves.

It is noted that during the operation of the gas stove, oxygen in the kitchen is burned and decomposition products harmful to breathing are released. Oxygen does burn off during cooking, but in small quantities. The premises in which gas equipment is installed are equipped with a ventilation system, which eliminates this drawback, and also allows timely removal of harmful substances from the air.

Causes of soot

Due to the gas mixture

The correct operation of the stove is evaluated by the quality of the flame. Normally, the gas ignites when it mixes with atmospheric oxygen. For normal combustion, the ratio of natural gas to air volume should be 1:10. Then the mixture (it consists of methane with the addition of propane, butane and ethane - for centralized supply, in a cylinder - on propane) burns out completely and evenly, flames of the same size and bluish-blue color. As a result of combustion, carbon dioxide and water vapor are formed.

If the gas mixture contains impurities, or there is not enough oxygen in the air for combustion, then the flame becomes yellow-orange, red and the burner begins to smoke. When burned, carbon monoxide and hydrogen are produced. The problem in this situation is not that the pan is smoky.Much more dangerous is the fact that due to incomplete combustion of gas, harmful substances are formed that accumulate in the air and can be harmful to health or cause a fire.

Burner malfunctions

• The jet hole is clogged.
• The flame spreader is deformed.
• The divider cells are clogged.

As a rule, only one or several burners form soot. A good cleaning will solve the problem.

In a centralized supply

If all burners are smoked, this may indicate the following problems:

• The settings that regulate the gas pressure have gone astray. If the gas is supplied under more than necessary pressure, then it will not have time to burn out completely.
• The air flow that mixes with the gas is not debugged. Some tile models are equipped with airflow adjustment. If they go astray, then the air does not enter in the right volume for complete combustion.
• Foreign impurities in the gas mixture. This is a very rare occurrence, because. the quality of the mixture is very strictly controlled.

When using bottled gas

The composition of bottled gas is somewhat different from natural gas. It can contain either pure propane or a mixture of propane and butane. In addition, the gas is under high pressure in the cylinder, which liquefies the fuel.

If a gas stove smokes from a gas cylinder, then the reasons are:

• Use of unsuitable jets. Since the gas in the cylinder is under high pressure, the nozzles must have a smaller diameter than with a centralized supply.
• There are a lot of impurities in the cylinders. Unscrupulous tankers can supply low quality gas, the mixture of which contains sulfur impurities that form soot.

Cylinders are used more often in the country or in rural areas where there is no main gas pipeline.When a gas cylinder smokes, it will not be possible to purify liquefied gas, so you should choose high-quality tankers.

Do-It-Yourself Nozzle Modification

If you have determined that the equipment has inappropriate nozzles, and there is no replacement, then on the Internet you can find many recommendations for alteration. They explain in detail how this can be done with a soldering iron, solder, sandpaper and sewing needles. It is recommended to check the performance of the resulting product empirically.

But be careful, it's very dangerous! The result of such an experiment may be a leak. Do not put your life and health in danger. Better buy a new part

Common Causes of Smoke

When the burner is working stably, the flame on it is blue, uniform, with almost no flashes. In case of malfunctions, red or yellow tongues of fire are noticeable, which indicates a lack of oxygen, or incomplete burnout of the methane mixture. Because of the yellow-red flame, the stove smokes. The main smoke factors:

• Excessive pressure in the system that does not correspond to the data sheet of the tile. The sudden appearance of strong soot is a signal for immediate contact with specialists (there are problems in the centralized gas supply).
• Black smoke - in a gas environment, a high content of foreign impurities. In apartment buildings, such situations almost never occur.
• Soot due to incorrect setting of the gas stove. It is unacceptable to carry out adjustments and adjustments without having the appropriate qualifications. Only professionals can properly adjust the tile.
• If the device is operated for a long time, the flame diffuser may be deformed. The element is resistant to contact with moisture, to high temperatures, but gradually wears out, loses performance. The divider needs to be replaced.

Typically, problems occur shortly after the device is first installed, or after it is shipped and reconnected at another location. Possible cause is clogged injectors.

Why does a gas stove burner burn badly

As a rule, any malfunctions are caused by a number of reasons, among which are typical for most models of gas stoves of domestic and foreign production. Among them we highlight the following:

1. The design of the device is broken.
2. Damaged gas hose.
3. Deficiency of the air-gas mixture.
4. Low gas pressure.
5. Wrong burner selected.

What if the burner does not burn well and makes sounds

All models of gas stoves are equipped with burners. In fact, this is the main working body necessary for cooking.

. This leads to a breakdown of the flame. The consequence of deformation is the generation of sounds, which should not be, by definition.

We must not forget that over time, a decrease in holes (nozzle) is observed. This comes from the formation of soot due to particles of food, grease, detergents getting into them. If a contaminated burner can be washed, then a deformed burner must be replaced immediately.

Wrong setting

If the gas stove is powered by a central system, a high probability of a problem lies in the incorrect setting of the device. Then you should seek help from specialists.Sometimes consumers try to solve the problem on their own, which is possible if you study the following features of the internal structure of the burner:

The burner includes a divider - this is a special part, outwardly similar to a flange bushing. For uniform distribution of gas, the divider has tower teeth located around the entire perimeter.

• A cover is placed on the divider - a special round stainless steel plate.
• Some models are equipped with an electric ignition system, so under the burner you can find a candle located on the side of the divider. In such models, the gas stove must be ignited by a spark.

Device under the burner with electric ignition

• In modern models, under the burner, you can find a sensor that determines whether the burners are on. If the gas does not burn, then its supply stops.
• Removing the lid and divider from the burner, you can see the jet - this is a special part that looks like a small bolt with a punched hole along the axial.

Troubleshooting Color Changes

If after cleaning the stove the color of the flame has not changed, call the gas workers

The main cause of failure is pollution. You can eliminate yellow and even red flames by simply cleaning the burners. In difficult cases, when it is necessary to exchange the nozzle or adjust the level of mixing of methane and oxygen, the help of a specialist is required. To remove pollution, no skills are needed.

The recommendations are simple:

• metal and enameled surfaces are cleaned with liquid agents; abrasives cannot be used;
• glass ceramics are washed with soapy water;
• holes are cleaned with a hard metal brush;
• do not use chlorine-containing products - these compounds burn with methane;
• after washing, wipe the plate with a dry cloth.

Dust accumulating on the surface of the stove, together with the air, enters the burner. Here it is charred, melted and sticks to the surface of the channel. Removing it is difficult.

The stove is powered by a gas line

Considering the numerous myths about gas stoves, the following common facts can be distinguished:

Danger. Often it is gas stoves that cause an explosion in an apartment building in the event of a gas leak. But as it turns out in practice - with a detailed investigation - it becomes clear that the danger lies in the improper operation of the stove by its owners themselves. Modern models are equipped with a security system - if the fire goes out, the gas supply is interrupted after a few seconds. As a result, there is little gas in the room - the volume will not lead to an explosion even as a result of a lit match.

The appearance of the burner, which needs repair

• Inconvenient use. This is evidenced by the housewives, who are forced to constantly monitor the temperature in the oven and the supply of fire under the pan in order to ensure uniform cooking. This factor has a second side - most housewives like it. In their opinion, self-regulation of the gas supply makes it possible to obtain both crispy crusts on pastries and fried meat. With electrical varieties, the presented actions are difficult to carry out.
• The emitted gas burns the oxygen in the room and emits decomposition products harmful to breathing.The combustion of oxygen during cooking is extremely small, especially if the room intended for the kitchen has large areas.

To understand the cause of soot, you need to know how a gas stove works. The device of any modern stove, in addition to the oven, includes such an important element as a burner, due to which the safe use of gas for cooking occurs. It consists of several parts.

1. The first thing you notice is the divider. It is presented as a gear flange bushing. The space between the teeth distributes the gas in a circle, forming an even flame.
2. Complements the design of the divider cover, located in the upper part of the burner. Most often they are made of durable stainless steel, but the material can be any.

Having disassembled the burner to the base, you can see a small bolt with a through hole in the middle. This detail is called a jet. Its diameter does not exceed one millimeter, and it is through it that the gas enters the divider. Most often, the part is made of brass or a material similar in properties. If the bolt hole is too large, the burner will smoke.

It is quite easy to replace the jet with a replacement kit - any home master can handle it.

What to do if the oven stops working

Electric oven device

If the owner is guilty of a breakdown or the warranty period has expired, there are 3 options:

• fix the problem yourself;
• find a private master;
• contact a post-warranty repair company.

The choice is made after self-examination. It happens that failures in the work of repair do not require.The equipment may stop working due to a door not tightly closed, the cord being accidentally pulled out of the socket, power outages.

If the model has an electronic display, the cause of failures may be a stuck button or a long press on it. The error is determined by the codes, they can be eliminated independently after a detailed study of the instructions.

If the heating element is faulty, the food is cooked for a long time, the element is pale on one side and not hot (it is checked after turning it off by touching the hand in the oven mitt). It is impossible to determine the breakdown of the thermostat on your own. A malfunction is indicated by an increase in the cooking time at the set temperature.

If the timer fails, the electrical module burns out, the contacts are damaged, you cannot do without a master. Replacing these parts is not expensive. Another thing is the block. Its cost is quite high, so replacing it is slightly cheaper than buying a new oven.

If the equipment is gas, then only two reasons for poor performance can be eliminated on your own: burner contamination and replacement of the door seal. If the burner is at fault, the fire is not evenly distributed. You need to remove the baking sheet and clean all the holes. If the door is to blame, then the hand substituted for it feels hot. The seal is inexpensive, anyone can change it.

In case of problems with gas equipment, it must be remembered that the gas is explosive, therefore, in case of any serious malfunction, it is better to contact specialists. The rules for the operation of this type of device do not provide for their independent installation and repair.

The main causes of soot

If the flame emanating from the gas stove is of a natural blue color and comes out of the burner evenly, then you should not worry, everything is fine with the stove. If the flames are red and yellow, and the gas flows unevenly, then the process of gas flow is clearly disrupted. The reddish tint of the flame indicates that the fuel does not burn completely, or that there is not enough oxygen in the combustion process.

Important! If the flames become scarlet in color, then this promises the appearance of soot. Most often, there are two main sources of soot:

Most often, there are two main sources of soot:

• low quality fuel;
• pressure is above or below normal.

Gas fuel contains a huge amount of mercaptan sulfur, which provides thick and black smoke. It also means high blood pressure. Most often, such a breakdown occurs in stoves connected to a low-quality cylinder with a reduced gas content.

But still, such a “disease” is more often caused not by a high-quality cylinder, but also by a malfunction of the nodes, in particular, a burner.

Wrong setting

If the gas stove is powered by a central system, a high probability of a problem lies in the incorrect setting of the device. Then you should seek help from specialists. Sometimes consumers try to solve the problem on their own, which is possible if you study the following features of the internal structure of the burner:

• A cover is placed on the divider - a special round stainless steel plate.
• Some models are equipped with an electric ignition system, so under the burner you can find a candle located on the side of the divider. In such models, the gas stove must be ignited by a spark.
