Thermal Power Plant Basic Definition Working Principle

This fan is called a Forced Draft fan or shortly FD fan. After combustion flue gas is produced and the same needs to be taken out of the boiler. This is done by another fan called ID fan or induced draft fan. Apart from these there are other kinds of fans used in the system like PA fan or Primary air fans SA Fan or Secondary air fans

Boiler induced draft fansCentrifugal ID Fans for boilers

The working principle of the boiler centrifugal induced draft fan is basically the same as that of the turbo compressor except that the gas flow rate is low and the pressure does not change much. Normally it is not necessary to consider the change of the specific volume of the gas that is to treat the gas as an incompressible fluid.

Primary Air Supply - an overview | ScienceDirect Topics

About 40%50% of the air required for combustion is added by forced draft fans at the primary vents at the bottom of the recovery boiler. The primary air supply is preheated to 150°C (300°F) and bums the organic compounds leaving smelt but maintains reduction conditions. The upper zone begins above the region of secondary air supply and has about 10%20% excess air above that required for complete
