What happens when the gas stove is turned off? What should I do?

Hello, there will be a sound when the gas stove is turned off, you can turn off the gas slowly, don't turn off the gas all at once, because the gas burns a big fire, and if you put out the fire all of a sudden, there will be a sound. Sometimes there is a situation when you turn on the gas, because the gas is turned on too much, and when you want to turn it off with a bang, it may be turned off too quickly, and there will be such a sound.

When the gas stove is turned off, there is a "bang" sound because the operation speed is too fast, when the fire is turned off, it is slower, turn off the gas tank first and then turn off the gas stove. The gas stove is located in the gap between the stove and the upper cover to supplement the lack of air during combustion, so as to promote combustion and reduce the generation of carbon monoxide and nitrogen oxides.

That's tempering. Stove tempering, also known as "discharge", is the burning phenomenon of "deflagration" caused by the flame retracting into the inner cavity of the stove (that is, the damper is on). Tempering occurs because the flow velocity of the mixture is less than the flame propagation velocity, and in order to prevent flashbacking, it is necessary to overcome the influence of factors that can increase the flame propagation velocity or reduce the velocity at which the mixture is ejected.

When the fire is turned off, it may be caused by the main valve that closes first, in which case the gas pressure in the pipe suddenly decreases, and the flow rate slows down, resulting in a backfire. Therefore, the valve on the stove should be closed first, and then the main valve.

The electrostatic precipitator is a device that collects dust in flue gas by electrostatic purification method. It is an ideal equipment for purifying industrial exhaust gases. Its net profit work mainly relies on two systems: discharge electrode and precipitation electrode.

When the electrode space of high-voltage direct current is input between the two poles, anions and cations are generated, which act on the surface of the exhaust gas dust particles passing through the electrostatic field, move to the electrodes of opposite polarity under the action of the electric field force, and deposit them on the electrodes to achieve the purpose of dust collection. The two-pole system has a rapping device, when the hammer type periodically knocks the two-pole device, the dust adhered to it is shaken off and falls into the lower ash hopper and discharged out of the machine through the ash discharge device. The purified exhaust gas is discharged into the atmosphere through the chimney from the outlet, and the flue gas purification process is completed at this time.

1. This phenomenon is a tempering phenomenon, check whether the gas source specified on the nameplate of the gas stove is consistent with the actual use. Check whether the burner is deformed and damaged. Professionals should be invited to inspect and repair to eliminate all potential safety hazards. Be.

2. There are impurities in the gas (such as rust and small particles of foreign matter), which affect the gas flow pressure in the process of gas transmission, causing the pressure in the gas stove transmission pipe to fluctuate and weaken, and the instability leads to a strong "bang" sound of internal air vibration. Or there are small insects, rice grains and other debris through the flame separator on the stove head into the inside of the stove. In this case, it is only necessary to detect whether there is a foreign object in the gas pipe and clean it up in time.

Precautions for the use of gas stoves:

1. Clarify the gas source. After installing the gas stove, be sure to read the product manual carefully before use. In order, open the valve in front of the stove on the gas pipeline, and then press the ignition device.

2. When using gas, be sure to leave someone next to you to take care of it, pay attention to the burning situation at any time, and adjust the flame according to the cooking situation.

3. In the process of using the gas stove, if you find that the fire is off, turn off the switch immediately and open the doors and windows for ventilation. When there is no smell of gas, find out the cause of the flame, and then re-ignite the fire after proper treatment.

4. Before stopping the use of gas or going to bed, check whether the gas appliance switches are all turned off. Closing the main valve on the gas meter, opening the kitchen window, and closing the kitchen door to the bedroom are the safest and safest practices.

5. If the hose connection method is used between the gas stove and the pipe, it is necessary to check whether the hose is damaged, aging and leakage. Apply soap to this area, and blow the bubbles continuously to see the air leak point. The service life of the hose is generally 18 months, and it should be replaced in time when it is aging to avoid accidents.

The gas stove has an air damper, which is used to mix air and gas, and mix it to the appropriate ratio to fully burn. The situation of your stove is that the damper is clogged with dirt, and the air intake is insufficient, so the fire head is small, and when the proportion of gas is large, it will deflagrate. Clean the stove by yourself, adjust the damper switch at the bottom of the stove, and adjust it to the right one.

Because the gas outlet in the gas stove is blocked (smaller), the flame is smaller than before, and there will be a banging sound when the fire is turned off.

Hello dear, 1. This phenomenon is a tempering phenomenon, check whether the gas source specified on the nameplate of the gas stove is consistent with the actual use. Check whether the burner is deformed and damaged. Professionals should be invited to inspect and repair to eliminate all potential safety hazards.

2. There are impurities in the gas (such as rust and small particles of foreign matter), which affect the gas flow pressure in the process of gas transmission, causing the pressure in the gas stove transmission pipe to fluctuate and weaken, and the instability leads to a strong "bang" sound of internal air vibration. Or there are small insects, rice grains and other debris through the flame separator on the stove head into the inside of the stove. In this case, it is only necessary to detect whether there is a foreign object in the gas pipe, and clean it up in time.

1. Bang bang is a phenomenon of tempering, which is a phenomenon in which the flame retracts back to the head of the burner through the fire hole and burns at the fire nozzle of the mixing tube when the gas is burning. When the flame burns, there is a lot of noise, the flame becomes shorter, and the inner and outer cone is not clear. Tempering disrupts normal combustion, the heat is not utilized, but can destroy the stove and even cause accidents.

In the event of backfire, the stove valve should be closed immediately, the cause should be found out, and the treatment should be carried out.

The causes and solutions are:

1. The burner or nozzle is clogged with dirt and causes backfire, which needs to be cleaned up.

2. There is air in the new hose.

3. If the air volume is too large, adjust the damper a little smaller.

4. If the pressure in front of the stove is too low, it is also easy to produce backfire.

5. When the stove is ignited, the temperature of the burner itself is too high, and it will also produce backfire.

Second, after mediating the tempering phenomenon, the flame should first be adjusted, and the adjustment method:

1. Open the stove valve to the maximum. At this time, if the inner and outer cone of the flame is not clear, or even yellow, it means that the air volume is not enough, adjust the damper to increase the air inlet volume until the inner and outer cone of the flame is clear and turns light blue.

2. Close the stove valve. The damper is generally not adjusted for a small fire. If the flame becomes shorter, it means that the air volume is too large, and the valve is slightly smaller.

3. Repeated adjustment, you can get a qualified flame in any state.

Workaround:

1. More air enters.

If there is a large amount of incoming air and the gas stove makes a thumping sound when the fire is closed, you can adjust the valve appropriately to control the amount of air entering the stove. The gas stove can be used to adjust the flame size through the button during use, and the valve on the gas pipeline is mainly used to control the natural gas.

2. Gas stove tempering.

The fire hole of the stove is blocked by food residue and the fire cover is displaced, which will cause backfire and "fire". As long as the stove has cooled down, clean up the debris, clean up the rust and ash and set the fire lid. Of course, there are also "guns" caused by the discomfort of damper adjustment, and at the same time, the root of the flame is detached from the fire hole (de-fire) and the phenomenon of yellow flame.

At this time, adjust the damper and observe the flame turning blue to ensure stable combustion. In addition, due to the different gas compositions and the pressure changes in the process of urban pipeline gas transportation, it will also contribute to the phenomenon of "fire" or "fire" when gas is used in some areas.

The slamming sound of the gas stove when the fire is turned off may be due to the fact that the fire cover has been placed in an incorrect place during the usual cleaning, resulting in backfire, and it can be solved by putting the fire cover back again. When replacing kitchen supplies, pay attention to the quality selection of the gas stove fire cover, the fire cover of poor quality is more likely to corrode and deform after being used for a long time, resulting in a bang sound when the gas stove is turned off, and the fire cover can be replaced again.

When installing the gas stove, it is necessary to pay attention to the adjustment of the size of the damper, if the damper is adjusted too large, it is easy to backfire, which makes the gas stove make abnormal noise, in this case, the damper can be adjusted back to the normal range. If the stove head of the gas stove is not placed correctly, or if it is used for too long and deforms or leaks, it will also cause the gas stove to make a banging sound when it is used.

Precautions for the use of gas stoves

Keep the kitchen well ventilated. Because carbon dioxide will be produced when the gas cooker is burned, if the flame of the gas cooker is not burned sufficiently, carbon monoxide may also be produced, which is harmful to the human body; Keeping the kitchen air circulating can ensure the oxygen needed when the gas stove burns, and at the same time, it can also exhaust the harmful gases generated during the combustion process of the gas stove.

There must be no flammable, explosive or volatile combustible substances within close range of the gas cooktop. Some families like to keep oil bottles, lighters, dry rags, etc. next to the stove. If you don't know it, these are potential safety hazards and should be removed in time.

The surrounding temperature of the gas stove is very high when it is used, especially after stir-frying on high heat or using the stove for a long time, these close items can cause disasters.

The gas stove will make a sound because of the phenomenon of backfire, which is also known as "fire", which is the combustion phenomenon of "deflagration" caused by the flame retracting into the inner cavity of the stove. After the stove is turned off, there will be a slight bang, the main reason is that there is more air entering, and the valve can be adjusted appropriately to control the amount of air entering. Common methods for eliminating flashbacks:

1. If the bottom of the pot is pressed to the point that the temperature of the burner head (nozzle part) is too high during cooking, causing backfire, then you should try to raise the position of the pot. 2. Because the stove nozzle is blocked by dirt and debris, which reduces the gas flow and causes the backfire, then the stove nozzle should be cleaned to make it unblocked. 3. Because it is a backfire caused by a large amount of air, that is, the damper is too large, then the low fire should be turned off, the damper should be adjusted, and the hose should be checked.

When the gas stove is ignited, there will be a banging sound because a large amount of gas leaks out, and there is a "deflagration" combustion phenomenon (i.e., the damper is on).

Causes and solutions:

1. When ignition, the main valve is opened too wide, which will cause the gas pressure in the pipeline to decrease suddenly, and the flow rate will slow down, so there will be a bang. In this case, the main valve can be opened slightly when igniting in the future.

2. The ignition function of the gas stove is not good. In such cases, the gas stove can be repaired.

3. The gas stove pipe is blocked. In such cases, it is possible to clean the gas pipes.
