Role of Primary Air Fan and Secondary Air Fan in Thermal

May 17, 2018· Secondary Air Fans. The air before entering the boiler is made to pass through an Air Preheater (APH) where the inlet air to the boiler gets heated by the outgoing flue gases and then this preheated air helps in reducing the moisture content of the fuel and further increases the boiler efficiency.
