Force Draft fan handles cold and dry air with much less specific volume and hence air flow quantity is lesser, for a given duty, than Induced Draught. Also we used world renowned German fills which has lesser static resistance than any other type of fill. Finally the velocity pressure which gets wasted into the atmosphere in Induced Draught is utilized effectively in Forced Draught system contributing in saving of power.
The exit air velocity is less in a Forced Draught system therefore the carry over loss gets minimized. Coupled with this very high efficiency drift eliminators reduce the total drift loss to max. 0.05% compared with 0.2-0.3% for other system. This also eliminates the drift nuisance as well as algae formation.
As the air entry is from one side and discharge from the top, the clearance required for forced draught is only form one side. Whereas for Induced Draught, clearance from all the sides is required, effectively consuming more space.
