What are the hazards of excessive fluidization air at the bottom of the return feeder in a circulating fluidized bed boiler?
When the fluidization air at the bottom of the return feeder in a circulating fluidized bed boiler is too strong, it causes the bed material inside the return feeder to be sent directly back into the furnace, preventing the formation of a proper level difference and thus preventing a positive pressure seal around the furnace
When the fluidization air at the bottom of the return feeder in a circulating fluidized bed boiler is too strong, it causes the bed material inside the return feeder to be sent directly back into the furnace, preventing the formation of a proper level difference and thus failing to create a seal that maintains positive pressure in the furnace
