超超临界燃煤机组循环水系统优化分析

Analysis of circulating water system optimization for ultra-super cirical coal-fired units

燃煤电厂为了选择较佳的循环水泵、凝汽器及冷却设备、构筑物的尺寸,需要对循环水系统进行优化。给出了根据厂址的自然条件和技术经济条件,在汽轮机的设计背压(排汽压力)设定下,对整个循环水系统进行优化的思路和方法。

For coal-fired power plant construction,in order to select better water circulating pump,condenser and cooling equipment,and to determine the size of structures,it is necessary to optimize the circulating water system.According to the natural conditions of the plant site and technical and economical conditions,based on the designed back pressure of the turbine(exhaust pressure),the optimization thinking and method for whole circulating water system were given.
