摘要
胜利发电厂对 200 MW 汽轮机通流部分进行了现代化改造。改造前热耗率为 8 733.5 kJ/(kW·h),改造后的热耗率降低了 523.9 kJ/(kW·h);高、中、低压缸效率分别提高到 85.87%、92.69%、85.68%,功率为 220 MW,每年净收益约为 1 500 万元,2 年即可收回改造投资。实践证明,对国产 200MW机组进行通流部分改造是提高机组效率、节约能源的有效途径。
Modernized retrofit of flow passage had been carried out for 200 MW steam turbine in Shengli Power Plant. Before retrofitting,the heat consumption ratio was 8733.5KJ/kW·h;after retrofitting,the heat consumption ratio dercreased 523.9 KJ/kW·h.The efficiency cf high,medium,and low prssurecylindershas been enhanced fo 85.87%,92.69%,and 85.68% repectively.The net income per year becomes about 15 million yuan RMB,the capital investment for retrofit can be recovered only in two years.practice shows that the scheme of retrofitting flow passage for home-made 200MW untits is an effective way for enhancing efficiency of units ,and for energy-saving.
