| Abstract: | From view of the condenser and circulation water pump,aiming at the problem of the turbine cold end system,the operational feature of its cold end system has been optimized,and an analytical method is proposed based on thermodynamics theory which is used to determine coupling characteristic between the optimized vacuum and the optimized circulation water flow.The operating mode of a 300MW unit's cold end system in a power plant has been verified by adopting this method and,the results show that the economy of units is increased by 0.116% after optimization. |
