    PA Fans, ID Fans, Draught Fans, FD Fans, SA Fans in

    ID fan creates negative pressure or suction to discharge the gases out after combustion from the furnace. Since ID fans can handle hot flue gases, they have more corrosion and erosion problems even when used with Electrostatic precipitators. The most common type of fans used as ID fans are the backward inclined blade centrifugal fans.

  • what is the thermal power equation used to drive an id fan

    What is the thermal power equation used to drive an ID fan

    ID stands for induced draft. It means that the fan pulls air from the process and exhausts to atmosphere. For example, in a boiler, the ID fan will pull air from the incinerator through the flue gas ducts and exhaust it up the stack.

    Induced Draft Fan: Working Principle - FBL Group

    ID fan takes the hot flue gases from furnace via dust collector (dust separation system or Fume Extraction system) and will deliver to chimney. ID fan produce the pressure lower than the atmospheric pressure in the system or we may say that ID fan produces the negative pressure in the furnace to remove the flue gases from furnace

    Damage analysis of the forced draft fan blade in coal

    The FDF blade has been run for 5 years and before its failure, the FDF experienced high vibration (14 mm/s). The forced draft fan is an axial flow fan horizontally in front of the boiler and the fan is single stage. Visual inspection, metallographic analysis, chemical composition and hardness test were carried out to find the cause of the failure.
