Forced Draft Vs. Induced Draft Fan - Student ...

Before they were applied to air-cooled units, Induced or Forced Draft fans were applied to Boilers for furnishing combustion air and they still are, to this day. They will probably always be optional methods for boiler combustion air source. I've used the combustion air fan on boilers both ways - induced or forced. The combustion calculations for the boiler are very different as I remember ...
