Why do we need Forced Draft and what is its function?

Forced draft(FD) :- A fan is used to force air into the boiler to provide more air for combustion. This is called FD fan. Forced draft fan, is used basically for providing the required quantity of hot air to the furnace for smooth and uniform combustion of fuel. FD fan will produce the positive pressure inside the system i.e. furnace.FD fans
