Balanced draft boilers use induced draft (ID) fans and/or their inlet dampers to control boiler furnace pressure. The typical control system has one controller that For example, because this fan sucks flue gas out of the furnace, on a high furnace pressure signal the fan should be blocked from decreasing
Cabinet fan systems that contain only one fan should have it configured to exhaust hot air out the top of the cabinet. There must be ventilation holes located elsewhere on the cabinet, preferably towards the bottom to act as an air intake. Using fans to push air out will cause negative or lowered pressure

FD fan supplies air to the Air-preheater, where it captures the heat from the flue gases coming from the Boiler Outlet. The pressurized air supplied by the Fan helps in providing enough draft equalizing the weight of the bed and the quantity to be supplied, hence creating fluidization of the sand in the furnace.
Fan coil units are available in two configurations, horizontal and vertical. The sound power levels Heat can be generated by an electric coil or separate gas-fired boiler. When a fan coil unit is located above a T-bar ceiling the noise it generates is difficult to control even with lined ductwork or silencers.

A fluidized bed is a physical phenomenon occurring when a quantity of a solid particulate substance (usually present in a holding vessel) is placed under appropriate conditions to cause a solid/fluid mixture to behave as a fluid.
Boilers have forced draft (FD) fans to supply air for combustion of fuel. Any trip of major equipment in boiler causes the boiler parameters to vary In these the FD, ID, and PA fans are large capacity fans, while the others are smaller fans. In the case of a pressurized boiler, only an FD fan is present.
Use of fan silencers, compressor silencers, mufflers on internal combustion engines, and acoustical material is required as discussed in TM 5-805-4 These data are used to determine air requirements and the weight of combustion by-products, both of which are used to determine boiler fan sizes.
