Forced Draft Fans Manufacturers

Forced Draft Fans are used in power plants. It supplies the air necessary for fuel combustion and must be sized to handle the stoichiometric air, plus the excess air needed for proper burning of the specific fuel for which they are designed. It provides air to make up for air heater leakage and for some sealing air requirements. Forced draft fans supply the total airflow except when an atmospheric-suction primary –air fan is used. It operates in the cleanest environment associated with a boiler and is generally the most efficient fans in the power plant. Centrifugal airfoil or variable-pitch fans are preferred for FD service. If steam coils or other means of heating the air ahead of the FD fans are provided, the consequent air temperature to the fans must be taken into account.
