差位式理论及工程应用——感潮水域冷却水运动及工程布置研究

Theory and engineering application of "outlet-in / outside -intake"works

本文介绍火(核)电厂冷却水工程布置,目前较普遍采用的设计理论要点;着重介绍差位式理论。应用该理论解决大亚湾核电站海工布置,提出南取东排方案;已在工程中采用,并投入运行。

Based upon the theoretical principle and the fruitful experience gained from thermal-hydraulic model study for cooling water projects along tidal rivers and sea bays, a new type of intake-outlet layout named as 'Outlet-in / outside-Intake' was initiated in China. The main points of the theory, the guideline in engineering planning, and the typical engineering applications are presented. This type of layout had been successively adopted in Guangdong Daya Bay Nuclear Power Station, and Lianbi Power Plant, etc. For the former, 200 million yuans of capital cost was saved due to the adopted hydraulic scheme instead of the original one.
