Forced Draft Fan (FD Fan)

‘B.D.FANS & ENVIRO ENGINEERING’ specialization and expertise of Forced draft fans one of the lasted and upgraded range of centrifugal fans for your choice. A unique combination of volume and pressure with high zone of flexibility are available.

An FD fan draws air from the atmosphere and forces it into the furnace through a pre-heater. These fans are located at the inlet of the boiler to push high pressure fresh air into combustion chamber, where it mixes with the fuel to produce positive pressure. The most common centrifugal fans used as FD fans are backward curved and airfoil centrifugal fans. In power plants, where coal is used as fuel for combustion, FD fans are used as primary and secondary air fans to regulate proper combustion and maximize the fuel efficiency of the process.

A typical FD fan arrangement uses inlet and outlet dampers to control and maintain the required air pressure inside the system. These fans have a wheel at the center that is hung on the shaft along with inlet boxes, silencer, filter and rain hood. When compared to ID fans, FD fans are easier to maintain and have cleaner operating conditions.

Capacity  from 200m3/hr. to 3,50,000m3/hr. and static pressure up to 3000mmwg.
