Even if the exhaust temperature of industrial gas steam boiler remains unchanged, the excess air coefficient of exhaust smoke increases and the heat loss of exhaust smoke increases. The excessive air coefficient of exhaust smoke is too high, and the power consumption of fan is increased, so it is found that the excessive air coefficient of exhaust smoke is too high in operation, so we must find out the cause and try to eliminate it.
The reasons for the excessive air coefficient of smoke exhaust are as follows:
