What is the problem of water in the gas stove pipe? What is the reason for the yellow flame of the gas stove?

Gas stoves are electrical appliances used for burning fire and boiling water at home. Generally, gas and liquefied gas are used for burning gas stoves, and the gas pipe plays a role in transmission. So what is the problem of water in the gas stove pipe?

What is the problem with water in the gas stove pipe?

There are three types of gas commonly used in households: natural gas, liquefied petroleum gas and water gas.

In the current urban upgrading and reconstruction, natural gas is mostly used. However, in the county and below, including rural areas, liquefied petroleum gas is still the majority.

The liquefied petroleum gas used at home is in gaseous state at room temperature and liquid under high pressure. Therefore, during transportation, the clanging sound in the gas tank is liquefied petroleum gas. When liquefied petroleum gas is burning normally, there is no water in the gas pipeline.

If there is water in the gas stove pipe, there are several possible situations:

1. The quality of liquefied petroleum gas is poor.

If the liquefied petroleum gas is not refined and contains more impurities, the liquid gas cannot be completely vaporized, the combustion is incomplete, the flame is small, and the flame is red, and the bottom of the pot is easy to turn black. In this case, you have to use professional equipment to evacuate the air tank and replace it with good quality liquefied petroleum gas. So we should not be greedy for small profits, and we must go to regular outlets to inflate.

Second, the temperature may be too low and the pressure may not meet the standard.

If the pressure is insufficient, the liquid gas cannot be completely converted into vapor. During the combustion process, the liquid gas will remain in the pipeline through the pressure reducing valve. In this case, we should try not to use gas outdoors in the cold, and try to cook in a warmer room.

There is another situation where the gas tank is used upside down.

Normally, gas cylinders are used upright, with the gas outlet on top. If the gas cylinder is inverted, the liquid gas will flow into the gas pipe through the pressure reducing device. This situation is the most dangerous, so everyone should never invert the gas cylinder at will. This situation is also the most likely to cause a fire and an accident.

No matter what the situation is, it is definitely not good to have water in the gas pipe. The best way is to find a professional maintenance technician to guide the water out of the gas pipe, or replace it with a new gas pipe.

What is the reason for the yellow flame of the gas stove

Flame combustion requires two basic conditions: one is the fuel itself, and the other is air. The blue flame is because the ratio of the gas output by the gas valve and the mixing ratio of the air circulation are relatively balanced, and only when it is fully burned can it appear a blue flame.

The yellow flame is because the gas input ratio is greater than the air circulation mixing ratio, so the flame cannot burn fully, and the fuel has low energy efficiency and high consumption.

Solution: When cooking, you can open the kitchen window to increase indoor air circulation. You can also adjust the "air mixing ratio valve" at the bottom of the gas stove to achieve better combustion efficiency.

Blue flame has the highest energy efficiency ratio among all flame states.

Why are there some air inlet holes at the bottom of the gas stove? The purpose is to increase the ratio of flame to air and achieve a better combustion state.

How to properly shut down a gas stove

Turn off the stove, make sure the flames on the stove are out, and then close the gas tank to make sure you are not causing suction, as the gas is compressed near the tank.

If the gas cylinder is turned off first, the gas is still in the gas pipe, and the stove is still burning, when the gas in the gas pipe burns quickly, the flame will burn to the gas pipe, causing the gas pipe and even the gas tank to burn. This is called backfire, which will not only damage the kitchen, but also cause serious fire.

In addition, if the gas valve is closed first and then the gas stove is turned off, the gas in the gas pipe will be almost completely burned. The gas and air in the pipe will be completely mixed when used next time, and will explode when the gas stove is ignited, causing danger.
