The vaporized liquid is carried away with the drying gases. Sometimes to save lots of energy, the exit fuel is partially recycled.
Fresh air is permitted to pass through a prefilter in advance of under-going a warmth exchanger to get heated. The underside on the bowl is the place the new air passes through. Simultaneously fan is permitted to rotate. The air velocity enhanced slowly.
The Blower is switched ON within the user interface. Given that the blower becomes operational so it attracts the air constantly from Air Heating Unit and in the tower from the decrease plenum.
