滨海热电厂冷却水布置及热污染特性比河道及水库型更为复杂。该文采用数值模拟的方法,对广东陆丰甲湖湾电厂附近的潮流特性及冷却水输移扩散进行模拟计算,结果表明东西分排方案造价低,温排水输运出现短路现象,取水温升超过2．6℃,且窝积在排水口附近。西取东排、深排方案温排水掺混扩散效果好,有效防止废热进入取水口,2008年夏季典型潮下的取水温升小于0．2℃,而浅排方案取水温升小于0．7℃,但易出现废热窝积现象。%In coastal and tidal estuaries, layout optimization of the cooling water drainage port is more complicated than that of river and reservoir. The characteristic of tidal current about the Jiahuwan thermal power plant and the transportation of cooling water is calculated with numerical model, and then the circulating current structure and its action on four type of drainage pattern is analyzed for the design of the power plant.
