摘　　要：基于我国火电站实际情况,提出应用给水加热型联合循环系统更新技术来改造我国传统50MW、125MW、200MW火电机组。该文侧重从联合循环系统特点出发,对它们热力特性和技术经济性能进行研究,得出改造3种机组的联合循环系统变化规律,并分析了改造后联合循环系统节能效果。Based on repowering the existing coalfired steam power plants of 50MW, 125MW, 200MW in China, this paper investigates feedwater heating combined cycle system. Their thermodynamic performance and technology economy are mainly studied from the characteristic of combined cycle system. The changing regularities of after repowering system are concluded, and their effects of saving energy are analyzed. The conclusions obtained here will play a practical instructive role in repowering the existing coalfired power plants. Figs 5, tables 5 and refs 6.
