The reason why the gas stove caught fire after being turned off was that the gas stove valve was not closed tightly.
When the valve is not closed in place or if the valve is defective, the apparently closed valve is actually still passing through gas, causing combustion, there are materials Combustibles in the stove body and stove pipe, sealing materials, residual gases and oil that leaks during use can all sustain combustion, particularly stoves that use liquefied gas as fuel .
Precautions for using gas stoves:
1. The cooker should be placed in a sheltered location, or a draft shield should be added to prevent the flame from escaping. escaping from the bottom of the pot.
2. Adjust the size of the air inlet to allow the gas to burn completely. The combustion flame must beand blue.
3. Make complete preparations for cooking before lighting the fire to avoid a “hanging fire.”
4. When making a soup or stew, you should first bring it to a boil over high heat, then use a low heat to keep the pot boiling without boiling over.
5. Use the stove shelf rationally. The height should allow the outer flame of the flame to contact the bottom of the pan to maximize combustion efficiency.
6. Adjust the size of the fire according to the size of the bottom of the pot, so that the flame is slightly bent after contacting the bottom of the pot and the pot, and the flame licks the bottom.
7. Using a pan with a larger diameter saves gas than a pan with a pointed bottom.
8. Try not to use steam cooking. Steaming rice takes three times as longtime than stewing.
If there is still a flame after the gas stove has been turned off, it may be because the valve is not closed tightly. It is recommended to repair it in time, otherwise it will be damaged. may cause a gas leak and present a hazard.
This answer applies to most brands of gas stove models such as Fotile, Vantage and Haier.
