Boiler Furnace Pressure Excursion and Set Points

26/8/2020 · The auxiliary power required for the operation of the induced draft fan(s) pulling gases from the boiler furnace increases as the furnace pressure falls for a given flow of flue gas. The increased fan power is caused by the greater head being developed by the fan and because lower pressure in the boiler causes more tramp air in-leakage; thus more flue gas that has to be handled by the fan.
