Why does the flame suddenly increase when the gas tank is closed and then extinguished?

It is not after it is extinguished, but at the moment when it is about to be extinguished, it will make a popping sound, because the mixture of gas and air has a ** volume ratio. Under normal circumstances, the proportion of gas is larger. There will be no ** phenomenon when the gas is turned off.

The ratio of gas to air will be reduced, and when it is reduced to the ** point, there will be a pop.

The main components of the gas tank (liquefied gas) are: propane and butane each account for about 50%, and butane is denser than propane, so if you stand upside down, you generally burn butane first. The main manifestation is that the flame is mixed with yellow flame and red flame when burning, and it seems to be very hot when burning (relatively before the handstand).

After the gas tank is used for a period of time, there will be a layer of slag at the bottom (corrosive), and when you stand upside down, it is easy to flow into the tank valve and pressure reducing valve, which is easy to cause damage to the corresponding parts.

It is recommended that you put the bottle straight (preferably for more than 2 hours) and then use the stove to see the situation. A short period of time is not a big problem, and it is recommended to minimize abnormal usage.

The reason for the sudden increase in gas tank when it is closed is that the internal and external pressure is different, so this is also very good, understand how much you have to wait for some physics, and you won't ask these bad netizens.

When the gas tank is turned off, the gas decreases and the air increases, and this part of the gas is fully burned, and the flame suddenly becomes larger, and then as the gas disappears, the flame goes out.

First of all, understand combustion: combustion is a physical and chemical reaction in which combustible substances violently combine with oxygen or oxidants to release light and heat. The three phases of combustion.

1) Combustible gas mixed with air; (2) Heating and ignition of combustible gas after mixing; (3) Complete the chemical reaction. The leaked combustible gas can only form a stable diffusion combustion at the fire site, and the combustible gas in the closed system is outside the first limit, and the propagation conditions are lost. The gas tank should be kept away from the fire source to prevent high temperature from causing physical problems.

When a gas tank catches fire, the flame burns in the air away from the gas tank due to the small pores of the gas tank and the high internal pressure. So it doesn't produce **. Fire drills are real.

Thermal expansion and contraction, and the tank is full of flammable and explosive substances such as gas.

"Gas tank" is a steel mobile pressure vessel, with the most dangerous, its wall thickness is only about millimeters (the new cylinder factory calibrated wall thickness), unusual, it is always under pressure from the internal medium, normal use of the internal pressure (i.e. pressure) megapascal (5 12 kgf square centimeter), the entire cross-section to withstand about 1000 kg of tensile force. "Gas tanks" are injured by collision, exposure and medium corrosion during long-term filling, transportation and use, which will produce defects such as fatigue cracks, pits, deformation, corrosion thinning, etc., which are the direct causes of accidents.

Most of the ** are generally leaked after the occurrence of open flames **.

When the main valve of the gas tank is closed, the gas stops flowing and should not be able to ignite. If it is said that the fire refers to the gas stove, etc., this may be the following situation:

1.Gas leakage: There is gas leakage in gas pipes or gas stoves and other components, resulting in gas outflow, even if the main valve is closed, it can still cause disasters.

2.Residual gas signs: Before closing the valve, the residual gas in the pipe is not completely burned out, and due to the lack of ventilation in the room, the gas accumulates, and the slightest ignition source will ignite.

3.Human error: In some cases, people mistakenly operate the main valve and think it is closed, when in fact it is not. At this time, if you get the switch wrong, it will lead to a disaster.

Therefore, once the gas smell or peculiar smell is found, it should be checked and dealt with in time to ensure indoor safety. When using gas, it should also be operated in strict accordance with the specifications and pay attention to safety.

1. The gas tank can be ignited when it is closed, which may indicate that there is a problem with the gas tank valve. Most liquefied gas tanks will have a barometer at the joint, and if there is, you can see the level of air pressure to prove whether the liquefied gas is in use. Be aware that when there is a gas leak, open the window for ventilation.

2. If the barometer shows that there is no problem, you need to consult the staff, and you can't continue to use this gas canister, because gas leakage is dangerous.

3. It is also possible that there is a problem with the sensor of the gas tank alarm, and for the sake of safety, the gas alarm needs to be replaced as soon as possible. to avoid serious gas leaks.

The gas expands when it is heated, and when you lock it up, it just explodes.

There are many possible reasons why the ignition of both sides of the liquefied gas and gas (i.e., coal gas) will cause it to go out, but if this is often the case, the most likely cause is the liquefied gas tank.

The air pressure in the gas stove does not match the air pressure required by the gas stove.

Specifically: the air pressure in the liquefied gas tank can be adjusted, too much air pressure may cause the flame to leave the flame, and too small air pressure may lead to no ignition. Therefore, when the left and right stove holes are used to work at the same time, when the rear ignition stove is ventilated, it may lead to insufficient gas supply to the gas stove that was originally burning, resulting in flameout.

Handling suggestions: It is recommended that users who often have this kind of problem call the customer service of the gas stove company and let the professional master conduct an inspection above.

The situation that the fire will go out when both sides of the liquefied gas stove are used at the same time is generally caused by insufficient air intake. happens to the cabinet user.

Combustion requires air, gas, and temperature. If the gas and temperature remain the same, it can only be caused by air.

Stoves are now generally burned at the fire lid by entering air and mixing with gas in the way of lower air intake or full air intake. It needs to be mixed with air at the stove head and then sprayed for combustion. At this time, if the amount of oxygen in the air is insufficient, it will cause the flame to stall.

The solution is to make a few small holes in the back of the cabinet to facilitate air circulation and ensure the air intake demand of the gas stove.

There are several reasons why liquefied gas can go out:

1. Check whether the combustion flame is too weak, if it can't reach the stove, the gas pressure is too low, the user who uses the liquefied gas stove suggests that it replace the new pressure reducing valve, and the coal gas and natural gas can be consulted and reflected by the gas supply company.

2. Now, many gas stoves are equipped with automatic protection devices, usually this kind of gas stove is installed with a solenoid valve at the inlet pipe, when ignition, the mechanical mechanism will link the solenoid valve switch, so that the solenoid valve can be electrified, so that the gas can be provided normally, when used, after the gas stove is extinguished due to the wind, overflow pot, etc., the ionization probe next to the combustion head of the gas stove can not "pick up" the ionization signal of the flame, so the protection circuit is started, and the gas solenoid valve is released to close the gas.

This is a more common fault, if you have a strong ability to do it yourself, you can open the cooktop, unplug the connection plug between the pulse ignition needle and the electrical box and then plug it back in, check if there is a contaminant at the plug of the electrical box to clean up, it can generally be solved, this phenomenon is an abnormal phenomenon of short circuit. If it still can't be solved, then you need to find an after-sales replacement electrical box, if your stove is not out of warranty, you can replace the parts for free.

Summary. Hello, glad to answer for you.

Hello, there are two possibilities, 1, there is a problem with the gas stove, check whether the fire hole at the fire head of the gas stove is blocked.

2. Whether there is really gas in the gas tank, sometimes it is a problem of gas quality, a poor gas tank is not very good to use in the end, and some do not rule out that there will be water added to it.

That's all I have to say, I hope it helps. Please move your little hands, like, thank you.

There is gas in the gas tank, and the gas stove is on fire, and the fire is slowly extinguished, what is going on?
