METHOD FOR RECOVERING WASTE HEAT OF CONDENSING TURBINE IN POWER PLANT

摘要

PURPOSE: A waste heat recovery method is provided to improve the efficiency of the generator by heating the compensating water with the waste heat from the steam of the condensing turbine. CONSTITUTION: A condenser(10) has a waste heat exchanger(20). The heat exchanger is connected with a compensating water tank(40) through a compensating water inflow line(25) and with a circulation line through a feed water heater(14) or a heat consumption section(30) using waste heat by a compensating water discharge line(26) in the other side. The heat exchanger is supplied with compensating water heated by the steam from the turbine through the compensating water inflow line and through the compensating water discharge line. The heat exchanger in a cooling water discharge line is supplied from a compensating water inflow with compensating water transmitting the heat of cooling water(23) from the cooling water discharge line.
