潮汐河道冷却水工程试验研究方法及应用

Experimental Method of Cooling Water in Tidal River and its Application

海湾及潮汐河口的冷却水工程研究近年来普遍受到人们的重视．由于受潮汐影响，其冷却水工程布置及热污染特性较之河道及水库型工程更为复杂．本文以新会电厂为例，详细说明潮汐河道冷却水工程试验研究方法及其排取水口布置形式，对多种布置方案进行对比试验和优劣分析，最终提出合理排取水口布置形式，且给出了电厂取水温升和热污染范围，为设计及环评工作提供了依据．

The characteristics of cooling water and its thermal pollution in tidal river and estuary are very complex due to unsteady features of tidal current. The arrangement of cooling water projects in tidal river is more difficult than in river or reservoir. Taking XH Power Plant for an example in this paper, experimental method of cooling water projects and arrangement regulations of outlet-intake schemes in tidal river are described in detail. Various outlet-intake schemes are tested and discussed. And the best scheme is given. The temperature of cooling water of the plant and the areas of thermal pollution on studied river are predicted.
