Cooling system of the Gas generator:
There are two cooling system of the gas generator. One is jacket cooling &
another is after cooler. For jacket cooling system there are two tanks above
the generator from where the water for the jacket cooler comes. The water
in the tank for jacket cooler doesn’t change. It is always recycling.
Cool water goes to the jacket from the tank, takes the heat of the parts of
the generator then the hot water goes to the after cooler to give up the heat
and the cool water returns to the tank for another cycle. In this way the
jacket water flows. In the after cooler the hot water of the jacket cooler
flows within a coil & the cold water of about 20 degree Celsius flows
from the outside of the coil. The cold water takes the heat of the jacket
water raises at 40-45 degree Celsius & goes back for cooling and the jacket
water send back to the tank by a pump.
In the after cooling system the normal water from the supply is used. The
water first send to cool the jacket water, then it sends to the cooling tower
to cool the water. The water from the after cooler reaches to the cooling
tower by a water pump. In the cooling tower the water is sprayed by six tubes
in a tank. Above the tank there is a fan of about 1.5m radius, which blows
out the heat of the water. Then the water goes to the pump from where it is
send to the after cooler.
