Abstract

As a State demonstration project in technology progress with a 300 MW unit

the cold-end system with the core part of rebuilt of the condenser was retrofitted comprehensively.The technical route for transformation of the entire cold-end system was put forward

and the flow characteristics of the working fluid inside the condenser and cooling tower were numerically studied.Moreover

the heat consumption rate of the optimized unit was experimentally investigated.The results show that

after the optimization

the heat consumption rate of the unit decreased by about 30kJ/(kW·h)

indicating the above technical route is reasonable and the transformation benefits are obvious.
