Gas stove bottom furnace fire is what causes

Gas furnace bottom of the fire caused by the reasons and the surface of the fire caused by the opposite, the furnace surface is the air in different situations to reach the furnace surface caused by fire, bottom fire because the hot gas back to the bottom, and the bottom Of the gasification agent caused by a mixture of fire, so it is an upward air, a downstream gas, the two different medium walking, the direction is different.
The reasons for the formation of fire bottom:
1, the air main (or air branch) of the gate valve or regulating butterfly valve is suddenly a significant small off, resulting in air mains or branch pipe low pressure furnace gas pressure is greater than the bottom pressure, causing the gas back to the process of gas back, Hot reduction layer and gasification layer, to further heating, hot gas reached the bottom of the furnace when mixed with air caused by fire, this time will cause the bottom water seal washed away, and then run the gas generated by the bottom of the phenomenon.
However, the top-of-the-range hearth fire is produced in a cold gas system consisting of multiple gas generators, which does not occur in a one-to-one situation (ie, a fan, a furnace, a conveyor) .
2, all blackouts, the remaining gas back, causing fire.
In the gas station, the general gas is generated by the force of the wind power, there is no gas pressure device, when the blower loss of electricity, the gas will not be pressure, so it will not produce the phenomenon of reversing, and thus will not produce furnace Bottom shot.
Treatment of gas furnace bottom shot is the rapid injection of a large number of steam to the bottom of the furnace, a positive pressure to form the bottom, and then the steam involved in the air and gas, can delay its re-shot.
