The flame of the gas stove is blue and red. Why?

The flame produced by the fully combustible gas is blue. Hotel stoves are generally red flames, because the burning rate is low, and a large amount of gas or fuel oil is not completely burned, which is lost in vain.

After the gas stove is ignited, the flame is light blue, with strong firepower, uniform flame height and high gas utilization rate. If the infrared gas stove is used, the gas will be fully mixed with the air before combustion, so that the combustion will be strong and sufficient, and the bottom of the pot will not be blackened after long-term use.

Extended data

The cause of gas stove fire

1, gas reason

When there is too much moisture or impurities in the combustion gas, the flame color will be very strong.

2. Dust causes

When there is dust at home or when the moisture and oil and gas in the air increase during cooking, it is also easy to appear angry.

3. Reasons for throttling

This can also happen if the damper is not well adjusted. Just adjust the damper at this time.

4, pot rack reason

Because the enamel on the surface of the pot rack is red when heated at high temperature, the flame will appear red around the pot rack because of the special material of enamel, and the enamel is the color of metal ions at high temperature.

Therefore, the red fire during combustion is not caused by the problem of the cooker, but by the above reasons, which will not affect the normal use and will not cause harm to people's health.
