Secondary Air Fan in Boiler - CR4 Discussion Thread

Mar 01, 2010 · The Secondary Air fan (also known as Forced Draft fan) provides the balance, and majority of combustion air. Its only pressure requirement is the flow of air through the ducting and airheater. Even at low boiler loads, the head requirement of the primary air system is similar to full load with additional mills in service.

China Industrial Boiler Blower Fan

The low secondary air supply of the B&W boilers is placed about 2 m (6 ft) above the primary air supply. This air acts as secondary air along the walls of the boiler, but as primary air in the char bed and, therefore, controls the height of the bed. Additional secondary air is needed; it is called tertiary air.
