摘　　要：介绍了定压和滑压运行对机组经济性的影响。同时针对某电厂国产210 MW供热汽轮机,分别在170 MW、140 MW、110 MW负荷工况下进行了定滑压运行性能对比试验,得到了机组滑压运行曲线。新的滑压运行方式有效地降低了汽轮机热耗率,提高了机组变负荷时的运行经济性。The influence of fixed and sliding pressure operation on economy performance of unit was introduced.In view of domestic 210MW heat supply turbine at a certain power plant,the sliding pressure curves were gained by performance comparison tests of fixed and sliding pressure operation under 170MW,140MW and 110MW.The new sliding pressure operation mode make the heat rate of steam turbine to be lowered effectively,and make the operation economy of varying load to be improved.

关 键 词：210MW机组 滑压运行 经济性 变负荷
