Forced Draft Fan |What is Forced Draft Fan|FD Fan

Forced Draft Fan FD Fan: Forced Draft Fan is a type of a fan supplying pressurized air to a system. In the case of a Steam Boiler Assembly, this fan is of a great importance.. As we know, for a Steam Boiler to generate steam, combustion must occur, be it any fuel (wood/coal/rice husk/pet coke/LDO/Furnace oil) and for combustion to exist one of its three main requirements, is the air.

Section 3 - Module 7: Boiler Draft and Flue Gas

The induced draft fan which is required to provide the same volume of air, is larger than a forced draft fan, due to the following: 1. The ID Fan must move a larger mass because flue gasses consist of the mass of fuel as well as the mass of air 2. the ID fan must be able to ahndle any air leakage in the boiler setting 3.
