Abstract:

The thermal balance calculation and comparison are carried out for the design working conditions and variation working conditions of the power generation station by taking the CDQ  power station of the plant of gas making with coke-making of Tangsteel as the study subject. On the basis of this, an analysis is conducted for the surplus heat recovery of CDQ power station, coordination of thermal energy utilization system and the heating power parameters matching between the inert gas circulation and steam circulation. Their analyzed results can provide a basis for optimized design and high efficiency operation of surplus heat power station.
