关于哈汽300MW机组运行经济性的分析

Analys of OPeration Economy of 300MW Units Made by Haerbin Turbine Works

通过对西柏坡电厂300MW机组运行的经济分析，找出部分设备及系统存在的问鼎。提出了；完善高压缸的结构设计；检修时既要重视轴封间隙的调整，又不要忽视各级间径向汽封间隙的调整；改进循环水泵使其出力达20000m3／h；更换质量较好的阀门,并加强阀门的维护和管理;继续改进和完善燃烧器内外调风挡的传动机构等措施。

Through economical analyses of the operation of 300MW units in Xibaipo Power Plant,the potential problems of a part of the equipment and systems are revealed. Some suggestions are proposed accordingly, they are: to improve the structure design of the HP turbine cylinderl during maintenance, both the adjustment for the clearance of shaft sealing and the adjustment of all stages of radial clearance of steam sealing have to be carefully done ito improve the output of circulating water pump to 20000m'/h; to replace all the low quality valves with high quality ones and to enhance the maintenance and management work of valves 3and continue to improve the actuating mechanism of the inner and outer register dampers to the burners.
