Forced draught boiler
WebForced draught: draught is obtained by forcing air into the furnace by means of a fan (FD fan) and duct-work. Air is often passed through an air heater; which, as the name suggests, heats the air going into the furnace in order to increase the overall efficiency of the boiler. Dampers are used to control the quantity of air admitted to the furnace. WebApr 14, 2024 · The forced draft fan and induced draft fan are two critical components of an industrial boiler that work together to maintain proper airflow and control the combustion process. The interlocking system between these fans is designed to ensure safe and efficient operation.
