高位收水冷却塔技术在百万千瓦火电机组中的应用

Application of cooling tower technology with high-collected water in 1000MW units

阐述高位收水冷却塔的技术特点,分析在某百万千瓦火电机组中的应用状况,提出确保火电机组安全运行的技术措施。该塔型配置的循环水泵静扬程可减少30%,轴功降低32.1℅,节能效果十分显著,可为同类火电机组高位收水冷却塔技术的推广应用提供参考。

The technical characteristics of cooling tower of the high - collected water is demonstrated, the application of 1000MW units is analyzed in one power plant and the technical measures for the safety operation of the units is proposed. The static head of circulating pump that is allocated in this type of tower has reduced 30% and shaft power has reduced 32.1%, which shows very obvious energy saving effect and provides references for the promo- tion and application in cooling tower technology of the high - collected water of the same kind of units.
