边界条件变化对凝汽器热力设计的影响

Effect of Correlative Condition Change on the Condenser Thermodynamic Design

就热力边界条件变化对凝汽器设计的影响进行讨论,结论是电厂应结合机组运行经济性、厂用电耗功以及凝汽器、循环泵、冷却塔等一次性投资成本等因素综合优化凝汽器背压、面积、循环倍率等外部条件,以获得一次投资成本和机组运行经济性最佳的结合点。

This paper analyzes the effect of changes in correlative condition on the condenser thermodynamic design, and proposes that the clients should select condensers taking into comprehensive account to cover the operation economy, power eomsumption, the direct investment cost of condenser, cycle water pump and cooling towers, etc. in order that the condensers procured by the clients are optimized in design with high economic efficiency during operation.
