火电厂最佳回水方式的研究

Research on the best way to return the condense water in power plant

电厂煤炭消耗量巨大,优化热力系统是实现节能减排的重要方式.针对抚顺热电厂1#机组,用等效热降法计算抽汽等效热降和抽汽效率,并分析了凝结水回水位置、回水温度、回水份额对电厂经济性的影响.给出了该厂最佳回水方式,并得出一般规律.

The coal consumption in power plant is so huge that we should optimize the thermal systems to achieve ener- gy conservation and emission reduction. Aiming at the No. 1 Unit in the Fnshun heat power plant, this paper calculated the steam extraction equivalent enthalpy drop and extraction efficiency with equivalent enthalpy drop method. The power plant efficiency of different return water position,retum temperature and return water portion was analyzed too. The best way to return the condense water was provided. At last, the general pattern was given.
