Aiming at the problem of the turbine cold end system

the operational feature of its cold end systems had been established under the different conditions from view of the condenser and circulation water pump. The influences of the steam turbine exhaust pressure under different load and the temperature of circulating water on the heat consumption of unit were obtained. Through field test

the relationship between the steam turbine exhaust pressure under different load and the influence coefficient of heat consumption rate was calculated. Thus

the heat consumption of unit model affected by the steam turbine exhaust pressure under different load was constructed to improve the accuracy of optimization conclusion with low load working.
