Why does the gas burner always go out?

Frequent flameouts of gas burners should first be eliminated from the equipment protection:

Insufficient gas flow in natural gas burners, e.g. pressure reducing valves.

The inlet filter, gas filter element, and gas valve inlet and outlet filter are blocked, and they can only pass through a small amount of gas, and the atmosphere will be too much. Just clean it up.

Look at whether the natural gas burner is the ratio of wind and gas of the fire is not set properly, the wind is relatively too large or the gas is relatively too large, it may exceed the range of ignition, the wind and gas are too large, or a section of fire may be blown out, etc., after adjusting the ratio of fire or regulating wind and gas, it can be solved.

Considering whether the natural gas burner is not matched with the combustion chamber and the natural gas burner, the internal pressure is too large to extinguish the burner, which makes the small fire and the big fire smaller or only burns the small fire (the small fire can be adjusted to a large size, the burner is selected, and the small fire can only meet the requirements), and it can also be dredged or increased The smoke exhaust port of the combustion chamber can be solved.

Secondly, consider the problem of the equipment itself: if there is a butterfly valve, see whether the drive rod of the butterfly valve is loose or falls off and does not work; The linkage of wind and air is broken; The valve group is broken, and its fire position cannot be opened; The line of the bimeter is wrong, it is broken, and so on.

The reasons for the flameout are: the sudden increase in gas pressure causes defire, the malfunction of the solenoid valve makes the gas ** intermittent, and the gas composition changes too much, and the moisture content is too high. The failure of the blower and induced draft fan, the load is too low, the negative pressure of the furnace is too large, the air leakage is too large, the air volume is too large, etc., so that the furnace temperature is too low, which can also cause the boiler to stall.

Prevention of boiler flameout: During the operation of the gas boiler, the change of the gas supply pressure should be closely supervised, and the abnormal situation of the gas supply pressure should be dealt with in time to ensure that the gas supply pressure is within the normal range. It is necessary to always understand and overhaul the composition of gas, and take necessary adjustment measures for boiler operation when the gas composition changes greatly.

The gas stove has an automatic.

Air cut-off protection, this situation is large.

There is more than one reason, that is, the protection probe detection thinks that the fire has been extinguished, and the gas is automatically cut off.

You need to manually disassemble the stove, unscrew the ignition needle, and pull out a part of it.

1. Check whether the probe on the stove can be burned by the burning flame, if not, it will cause gas outage to extinguish the fire. At this time, there are generally two situations, one is that the stove is dirty, and the flame against the probe does not burn to the probe, but the damper is not properly adjusted, so that there is no gas in the flame against the probe, try to adjust the damper, and know that the flame at the probe site can continue to burn the probe.

2. Check whether the connection between the probe and the controller is intact, and if the plug connector is dropped, plug it back in.

Notes:The extinguishing device of the gas stove will go out if it is not heated to the temperature of the suction valve.

Using the physical properties of metal, it belongs to temperature difference induction, and the flame-out protection action is controlled by temperature sensing. When the temperature drops below a certain temperature, the gas supply is immediately cut off, which is an instant reaction, and the general extinguishing time is about 5 to 10 seconds.

01 Poor circuit contact.

If the gas stove is used for a long time, it is easy to have poor contact, resulting in the failure to turn on the special fire or automatically turn off.

In this regard, we can check whether the positive and negative poles of the battery box are rusty, and whether the wiring is in poor contact. If there is, remove the rust and connect the lines accurately.

02Check if the battery is charged.

The gas stove battery is dead, which is the direct cause of the flameout.

In this case, we need to check if there is gas on the gas stove. Yes, at all. then determine whether it is a problem with the battery; If the battery is out of charge, replace it with a new one.

03 Pipeline blockage.

Under normal circumstances, the gas stove pipe is blocked, which will also cause the gas stove to fail to ignite or turn off automatically.

For this, we need to check the outlet valve. Normally, if you can smell the gas, but the gas stove does not catch fire, it is likely that the gas is clogged. At this time, we only need to dredge it in time to use it normally.

04 Overvoltage protection.

Nowadays, many gas stove products have added overvoltage protection function in order to ensure safety. When this kind of gas stove is used, once it exceeds the standard pressure, it will not be started again, and it will naturally not ignite.

For this, we only need to replace a pressure reducing valve.

05 Ignition needle position deviation.

When the gas stove is used, there are certain requirements for the distance between the ignition needle and the fire cover. If the distance deviates too much, the gas stove will not catch fire.

What should I do if the gas stove turns off automatically? The method of repair is simple.

Hello. Generally, the gas stove will automatically turn off after a while.

It is due to a problem with the ignition needle of the gas stove.

Generally, the stove is disassembled, the ignition needle is unscrewed, and a part of it is pulled out.

However, the ability to do it yourself is not strong, so let's find a maintenance worker!

After all, gas stoves are very dangerous.

Is the solenoid valve related to the ignition after a while, please help.

It feels like the gas stove is broken, and the gas stove in my house is also this kind of problem, just replace it with one, and throw away the old one.

The automatic fire is not used, how to deal with it, thanks.

There may be a problem caused by the improper installation of the temperature probe position, or there may be a problem with the ignition controller or flame-out protection.

Because there is no gas, it will automatically turn off after a while.

The safety protection device for accidental flameout is broken.

Poor circuit contact: If the gas stove is used for a long time, it is easy to have poor contact, resulting in failure to ignite or automatic flameout.

In this regard, you can check whether the positive and negative poles of the battery box are rusty, and whether the wiring is in poor contact. If there is, remove the rust and connect the lines accurately.

Precautions: After using the gas appliances, please pay attention to close the valve in front of the stove and the riser valve. When using a gas stove, the fire should be extinguished, and the stove switch and pipe valve should be turned off casually. Natural gas leakage is very easy to flash explosion when exposed to open flames or household appliances, and it is necessary to prevent boiling soup and boiling water from overflowing to extinguish the stove fire or be blown out by the wind.

Because the bottom of the gas stove is abnormally high, in order to prevent dry burning, the gas stove triggers an automatic flame-out device to cause the flame-out. In 2009, the state promulgated the "National Standard for Household Gas Cookers", and the automatic flame-out protection device became the standard configuration of gas stoves, which avoided gas leakage caused by accidental flame-out of gas stoves.

However, in recent years, users forget to turn off the fire, burn the pot dry caused by the news of safety accidents have been reported frequently, when the bottom of the pot is abnormally high (298), the gas stove will automatically make the judgment of burning the pot, and quickly turn off the gas source through the sensor to extinguish the fire to avoid accidents. At the same time, when the gas stove detects that the user forgets to sit on the fire, the gas stove will automatically turn off the fire within 3 minutes to ensure the safety of the family's daily stove.

Summary. Hello, I'm glad to reply to you, the reasons why the gas stove goes out in the middle of burning: 1. It may be that the contact of the battery is not good, or it may be that the battery is out of power, and it needs to be reinstalled or replaced.

It may also be that the connected pipe is flattened or folded, and the pipe should be straightened out. Then observe the size of the flame, if the flame is weak and cannot touch the stove, it means that the pressure is low, and the pressure reducing valve should be adjusted.

Hello, I'm glad to reply to you, the original cause of the gas stove burning out in the middle of the liquid: 1. It can be guessed that the contact of the battery is not good, or it may be that the battery is out of power, and it needs to be reinstalled or replaced. It may also be that the connected pipe is flattened or folded, and the pipe should be straightened out.

Then observe the size of the flame, if the flame is weak and cannot touch the stove, it means that the pressure is low, and the pressure reducing valve should be adjusted.

2. It may also be that the position of the induction needle has deviated, resulting in the flame being contacted without filial piety, and the position of the flame should be adjusted in this case. It is also possible that there is a problem with the thermal probe and it cannot hold the flame. You can press and hold the switch for ten seconds when ignition, and then release it, and the probe will heat it through the heat sensitivity, so that the flame will not go out.

3. The premise is to ensure that there is gas, and the fire will be extinguished if there is no gas. Hope it helps you and I wish you all the best in your life.

Hello dear, it is a pleasure to serve you, about your question: "Why does the gas burner always go out?" "It's been found:

The gas burner is always out of the cause 1The fire is extinguished after the unstable sale of the gas source caused by the fluctuation of the flame, 2When the flame detector is faulty, the flame detection probe is grounded or too dirty, and the normal flame cannot be detected, and the flame is extinguished; Circuit failure, unstable power supply or lack of phase, resulting in flameout in the process, etc.

In the case that the accessories are not broken, the reasons: 1. The most common is the flame signal problem, which is not detected or weak or the signal transmission fails. This fault generally ignites for no more than 10 seconds; 2. The problem of internal pressure is that the current power of the burner does not match the overall pressure formed by the combustion gas in the combustion chamber or flue of the equipment.

3. Fuel failure, that is, the fuel pipeline is blocked or the valve is opened or the pressure is not enough to make the fuel not on after ignition. Vertical destruction contains.

The heat source equipment of the dryer fueled by gas has 2 medium and infrared stove or gas burner.

1. If it is equipped with a gas pressure protection device, when the gas supply pressure of the gas pipeline is not enough, it will be burned for a while and the gas valve will be automatically cut off. This will also cut off the power to the heat source device. In this case, one is that the gas source is about to be exhausted, and the other is that the pipe is sold slowly, the flow is not enough, such as the valve can not be fully opened, the valve or pipeline is frozen, etc.;

2. The infrared stove or gas burner is equipped with a flame sensing device, when the flame is formed for about 10 seconds, there must be a stable and strong enough flame signal to the combustion controller, otherwise the burner will immediately cut off the gas valve and alarm.

3. Provide specific combustion equipment models and brands, and I can provide more targeted answers.

There can be a variety of reasons why a gas burner goes out, which may include the following:1Insufficient gas**:

If there are a large number of people using gas at noon, the gas** may be affected, causing the burner to run out of gas and turn off. 2.Clogged gas pipes:

The gas pipeline may accumulate some debris during use, especially when the gas consumption is high at noon, the gas pipeline is more likely to be blocked, causing the burner to stall. 3.Ignition failure:

The igniter is an important equipment for the ignition of the burner, and if the igniter fails, it will also be prepared to cause the burner to stall. 4.Combustion of the gas valve failure:

A gas valve is a device that controls the flow of gas, and if the gas valve fails, it will also cause the burner to stall. It is recommended that you contact a professional gas burner maintenance personnel for inspection and repair to determine the specific cause of the problem and solve the problem.
