  • Losses are obtained from (Heat input-Heat output).

Heat balance discloses many important information on quality and quantity of energy. Coke oven operates at output temperature is assumed to be . The heat output in tar, coke and coke oven gas is of high quality as they are discharged at and must be explored in terms of reuse.

Also output consists of potential energy, i.e. calorific value let us consider each heat output and analyze in terms of reuse.
