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 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. And this requirement is compensated by a Forced Draft Fan . This fan supplies air to the Air-preheater, where it captures the heat from the flue gases coming from the Boiler Outlet. Nowadays, fluidized bed combustion is one of the promising ways of collecting more energy through combustion for solid fuels. But this wouldn’t have even been so famous if there wasn’t any Forced Draft Fan . Whether it is Bubbling or Circulating fluidized bed combustion incorporated Boiler. This phenomenon of fluidization is achieved through a Forced Draft Fan only. Let us consider Bubbling Fluidized Combustion, Proper design...
