Why does a gas stove smoke from a gas cylinder?

An indispensable attribute of any kitchen is a gas stove. But not everyone knows how dangerous this device is, which needs to be handled with extreme care. Due to constant use or manufacturing defects, the stove may become unusable. If you notice that the stove is not working well or is broken, do not repair it yourself. Without certain knowledge, repairs can lead to irreversible consequences. The most common type of breakdown is “smoking”. Let's figure out what it is and how to prevent this attack.

Main causes of soot

If the flame coming from the gas stove is a natural blue color and comes out of the burner evenly, then there is no need to worry, everything is fine with the stove. If the flames are red and yellow, and the gas flows unevenly, then the gas flow process is clearly disrupted. A reddish tint to the flame indicates that the fuel does not burn completely, or that there is not enough oxygen during the combustion process.

Important! If the flames acquire a scarlet color, this promises the appearance of soot.

Most often, there are two main sources of soot:

• low fuel quality;
• pressure is higher or lower than normal.

Gas fuel contains a huge amount of mercaptan sulfur, which produces 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 an “illness” is more often caused not by a high-quality cylinder, but also by a malfunction of components, in particular, the burner.

Poor quality gas from a cylinder

If bottled gas contains sulfur impurities, then you have the right to file a complaint with Rospotrebnadzor or similar organizations in this profile. To file a complaint you will need: a cylinder refill receipt; directly the gas cylinder itself, for examination; application in proper form. Most often, organizations complete such cases peacefully and quickly.

If soot has formed on your stove, then you should follow a certain algorithm.

1. Try moving the cylinder or stove to another place in the room.
2. Then you should contact the organization where the cylinder was purchased or filled so that they try to explain the reason for the appearance of such a huge amount of sulfur.
3. If the organization does not make contact, write a complaint in order to restore justice and receive financial compensation for damaged property.
4. If your comrades purchased gas from this organization, find out from them whether their gas stove smokes. A friendly environment is much better and more enjoyable than a trial.
5. Before filing complaints with the appropriate authorities, be sure to check that your gas equipment is set up correctly.

Incorrect gas stove setting

Have you noticed that the burner in your kitchen stove is smoking? This means that the outlet pressure is higher than the specified norm.If you want to study the inside of the burner in more detail, then you should know the following important information.

If you use a modern electric stove, and not an old one left over from Soviet times, then it is equipped with replaceable jets in two versions, with different diameters. And the burners consist of the following components:

1. A divider that serves to distribute gas across the entire burner area evenly and without failure. In appearance, it resembles a bushing made using a flange, cut along the general perimeter.
2. The divider cover is made of stainless steel and has the shape of a round plate. It is located on top of the divider.
3. Most often, the designs of modern stoves are supplemented with an electric spark plug. It is located on the side of the divider. The working process is as follows: the spark becomes a signal for ignition, and electricity is ignited using gas fuel. There is a temperature sensor located near the spark plug. It was installed to assist in the operation of the stove. It determines whether the gas is burning or not. If the gas suddenly goes out, a special electromechanical device designed to regulate the flow of all types of liquids and gases, which stops the supply of fuel, which helps ensure the prevention of fire.
4. The jet is located under the divider. It is presented in the form of a bolt, which is pierced with a through axial hole. If the slab is smoked, this hole becomes extremely large. On the jet there is a yellow part made of brass and bronze. The jet ensures safe operation and durability of the stove.

Modification or absence of the plate jet

In the modern world, gas stoves are equipped with two sets of jets. But it doesn't come without problems. Namely, the design of the stove is smoked as soon as it is transferred from the main gas pipeline to bottled gas. Modern gas stoves should also include a socket wrench.

To avoid uneven insertion of the nozzle, make sure that the hole diameter is 0.8 millimeters. Otherwise, gas leakage may occur. This problem, in turn, will lead to a gas explosion and the house will “fly up” into the air. Only a professional should perform such work to replace jets. He is required to have all the necessary skills and increased attention to the process in order to avoid tragic consequences. And, of course, the quality of work must be at the highest level.

Unfortunately, the second set of jets for the gas stove is missing? There is no way to purchase the necessary parts yourself? It's no problem. You can do everything yourself. For this you will need: a soldering iron, a set of sewing needles of different sizes and an alloy for soldering.

The solder will lie tightly on the metal if the oxide layer comes off from the multicomponent alloy. But don’t rush to use rosin. To begin with, wipe the jet with alcohol (alcohol wipe). Next, we rosin the hole itself and the cap. Accordingly, the oxide film is removed. Apply a drop of alloy for soldering. The hole will soon be filled with tin.

Using sandpaper, the alloy drop is leveled to the same level as the cap. Then select a small sewing needle and poke a hole. Using a larger needle, create a hole up to 0.5 millimeters.For measurements, you can use a universal tool designed for high-precision measurements of external and internal dimensions (vernier calipers). We screw the jet back. We are testing gas fuel. If the gas flame is blue, without yellow tongues and does not smoke, then the result corresponds to the descriptions stated in the requirements. Let's move on to the second jet. We take it out and use needles to enlarge the hole. We check the flow of gas every 0.1 millimeters.

Important! The hole should be parallel to the axis of the jet. Otherwise, gas will accumulate, which will provoke an explosion of the gas fuel. After replacing the jets, it is necessary to observe the stove and the nature of the escaping gas.

In old gas stoves, unfortunately, there is no possibility of replacing jets. But on the other hand, there is a mechanism for regulating and controlling the strength of the flow of incoming gas fuel. You can try to configure the mechanism correctly.

The adjustment is made by turning the tap, since the gas cylinder is equipped with a valve with a conical thread. Therefore, there is no need to open it completely.

Solving the problem yourself

Before starting work, you need to make sure that the gas cylinder is completely empty. You should avoid performing unnecessary actions in relation to the conical tap. Since it is installed under heat, we use a construction machine for drying. You can use a torch, but the risk of a cylinder explosion increases several times. Increase the valve temperature. When exposed to heat, the thread moves very easily. We replace the old faucet with a new one. First, we screw the part as much as possible, then we heat it with known devices and screw it until it stops.

It is not difficult to guess that in a gas cylinder, after some time, a condensation product of the vapor state of liquids appears. The resulting substance is disposed of in specialized places, away from large crowds of people. At the same time, without violating the law on environmental pollution.

When repairing and replacing parts of gas stoves, you cannot use plumbing equipment. It is not compatible with electric models of kitchen equipment in any way. The explosion will occur, it would seem, for no particular reason. But the real reason is the incompatibility of the installed parts.

What should you do if your gas stove smokes? First of all, you should call number 04. Specialists will tell you the correct numbers and give advice on initial actions.

If the cause of smoking is incorrect installation of the jet or other parts, you can fix everything yourself. But this is only possible if all safety regulations are followed. The following important aspects should be highlighted:

1. Modern stove models are equipped with two jets. They, in turn, are of different diameters. This is done so that the disposable stove can be switched from a central gas system to a gas cylinder. The general system requires a jet with a diameter of one millimeter, but a cylinder - 0.8 millimeters. The switching process can be done independently if both jets are included in the kit.
2. If you replace the jets yourself, it is possible that their position will deviate by several degrees from the norm. As a result, the gas will not be supplied at full capacity, and the distribution will become uneven. Such violations will lead to a gas fuel explosion.Therefore, when replacing parts of a gas stove yourself, you should do it carefully and follow all safety requirements.

Regardless of the complexity of the work performed, doing it yourself increases the risk of problems. All actions must be thought out in advance and performed carefully.
