Backfire refers to the phenomenon of rapid deflagration that occurs when the high-temperature incomplete combustion products (flue gas) generated by fuel-rich combustion meet fresh air. The backfire is a special fire phenomenon that after the building fire with limited ventilation enters anoxic burning and even smoldering, hot smoke is suddenly burnt due to the sudden and massive supplement of fresh air. In the combustion process and the high-temperature environment after the combustion is finished, the combustible materials in the chamber still carry out pyrolysis reaction, a large amount of combustible gas can be gradually accumulated in the chamber, and once ventilation conditions are improved, air can be supplemented in a gravity flow mode to be mixed with the combustible gas in the chamber. When the mixed gas is ignited by ash, a strong and rapid flame propagation is formed, and when the mixed gas is combusted indoors, a huge fireball is formed outside the ventilation opening, so that the damage to the indoor and outdoor environment is caused. Because of the suddenly and the strong destructiveness of the backfire fire, the fire disaster can be saved for firefighters, and the life safety of people is seriously threatened.
