 The Forced Draft Cooler is basically gas to air heat exchanger. It is used  to cool the exhaust gases from the Kiln, boilers etc.  The hot gas passes through vertical tubes and ambient air is blown over the tube in number of modules for cooling the gas.  There are  two  to four passes in the hot gas side depending upon the quantity of flue gas and its temperature.   In conventional design where cold air is passed through  horizontal tube bundle and hot flue gases Is blown over the tubes there is a loss of heat transfer  co-efficient.  Unlike the gas- conditioning tower, dry type forced draught cooler does not require water and water  disposal  is not a problem.  There are number of FD Fans  for cooling.   Hence  there is more flexibility in regulating air flow to maintain accurate exit  temperature. Cooling tube  banks are of vertical design with no chance of dust  accumulation.   All three modes of heat transfer i.e. radiation, conduction and convection are used simultaneously to dissipate heat thereby reducing less power consumption. Also  there is no requirement of compressed air for system to clear any chokeage problem
