火力发电厂循环冷却水浓缩倍数的优化研究

摘要

The water source of some 300 MW units was ground water. Techno - economic comparison of several schemes was carried out concerned with water saving. The results showed that the 6 cycle of concentration was an optimal cycle of concentration, which had the advantages of reliable operation, less investment, low operation cost, etc. The scheme provided an option for the design of similar projects.%某300Mw亚临界机组水源为地下水，为节约用水，进行了循环冷却水浓缩倍数的多方案技术经济比较。结果表明，6倍浓缩倍数具有运行可靠、投资省和运行费用低等优点，为循环冷却水最优浓缩倍数，对类似工程设计具有一定的借鉴意义。
