One of the typical malfunctions of gas stoves is soot on the bottom and walls of dishes. The situation is unpleasant, but the breakdown may well be fixed. The article discusses why a gas stove smokes and what to do.
We are looking for a reason
In a normally and stably working stove, the flame will be uniform, blue. If for some reason the combustion is disturbed, the flame changes color to bright yellow or red. This suggests that the fuel does not burn completely or does not have enough oxygen. It is a red-yellow flame that indicates the existence of a problem.
Why does a gas stove smoke? Practice has shown that the problem has two main causes - it is low-quality gas and pressure. If the first contains a lot of sulfur, then the stove will smoke with thick black smoke. The same will happen if the pressure in the gas line is higher than the standard. Most often, these problems occur in stoves powered by gas cylinders. But also these signs can talk about other breakdowns.
The main faulty unit is the burner itself. In the case of it, there may be either a blockage of nozzles or a deformed divider.
Line pressure
Why does a gas stove smoke in an apartment? Rarely, the cause is a change in gas pressure in the line. This can be diagnosed by the fact that each burner smokes the same way. To make sure that the problem is in the trunk, you can interview the neighbors.
Gas
This is another reason why the gas stove smokes. We have already mentioned this problem. Suppliers often save and dilute propane. It may contain a large amount of sulfur - it gives thick smoke and soot.
How is the hob arranged?
Blue fuel is blown into the cavity of the burner through a special nozzle injector. But this should not begin. In modern gas stoves, this part consists of several elements: a divider and a cover. The first is a flange sleeve having teeth. Thanks to them, gas can be distributed in a circle. Thus uniform burning is formed. The lid is a complement to the design and is located at the top of the burner. On modern stoves, manufacturers use divider covers of various materials. Most often it is a stainless steel.
In the slabs, over the construction of which experienced engineers thought, all this is supplemented by a candle mounted on the side. If you get the divider and its cover, then the nozzle will become visible. It is a bolt with a small through hole. The bolt is most often made of bronze or brass. The numbers on the hole indicate the diameter of the nozzle. Gas passes through the head of the bolt and enters the divider. This is the answer to the question: "Why does the burner of a gas stove smoke?" In such cases, the nozzle is too large. It makes sense to make sure that the nozzle matches the gas. Most gas stoves have jets designed for methane flowing through urban gas pipelines. The pressure in the system is small, and the hole, respectively, should be larger. Propane is pumped into the cylinders and the pressure there is higher, therefore the nozzle should be smaller.
Outwardly, the burner for the main or liquefied gas in the cylinder does not have any differences. The difference between them is only in the face value of the jet. If the latter does not fit, then replace it. But the nozzle must be suitable for a particular plate, otherwise the replacement will not solve the problem. If the item does not fit the plate, sometimes it cannot be installed. An incorrectly installed nozzle can result in a gas leak, which is dangerous.
Now we know why a gas stove with a cylinder smokes. Most likely, the nozzle in the city plate, and not a balloon.
How to clean the nozzles?
One of the reasons is clogged nozzles. Because of this, the gas pressure changes and the stove will smoke. Let's look at how to clean the nozzles. In any work with gas stoves, the first thing to do is to shut 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 required. It is enough the needle tip to rotate in the hole.
If there is dirt, then it does not hurt to clean the divider with a cover. To do this, you can apply a toothbrush, gel for dishes, warm water. Do not clean with a nail or wire. Modern burners are made of delicate materials and will not withstand such an act of vandalism. Next, the burner is wiped dry, dried. Then (after about half an hour) set in place.
The divider is deformed
According to the model of a gas stove, the corresponding dividers are also purchased. Now pick up any spare parts is not a problem. Their price is also not too expensive.
If the oven smokes
Often the reason why a gas stove oven smokes is a jet. Injectors may need to be replaced. In the bulk of the models of gas stoves and ovens, the nozzle is located behind the left wall.
The first thing to do is turn the screws out and take out the burner. There is the nozzle. During prolonged use, the nozzle can practically stick to the nozzle. If this happens, then it must be lubricated with a special tool and wait a few minutes. Collect in the reverse order.
Air supply
If there is not enough air, then this is the answer to the question: "Why burn gas stove burners?" In this case, even serviceable burners will accumulate. The air supply must be increased. How? This is done by adjusting the air discs. Unscrew the locking pin and adjust, but carefully. After adjustment, the flame should be up to 2.5 centimeters in size. It also makes sense to listen to the operation of the burners. Normally working equipment should not make any sounds.
If the burner still does not work correctly, then the nozzle screw increases the fire.
Refining the jet
Now we know why the gas stove smokes. To get rid of the problem, you need to change the hole in the nozzle. The larger its diameter, the lower the pressure. It is important to strictly observe alignment and verticality. The nozzle is changed by soldering.
The element is removed, and then oxides are removed from its surface. Then a drop of tin is placed on the head of the nozzle. It should close the hole and cover the edges of the cap. Remove excess with emery or file. The area is equalized so that a drop of tin is slightly higher than the hat. A thin needle pierces the surface of the solder. This will create a new hole. When its size is half a millimeter, the nozzle is screwed into place. For propane plates, the hole should be equal to one millimeter.
If the flame is even and blue, then the work can be considered finished. When the burner warms up, rare yellow tongues are perfectly acceptable. If the flame is small, then the hole is increased by another 0.1 mm and checked again.
