摘　　要：采用三维流场设计方法,在保留原低压缸和主轴的前提下,对某电厂6号100MW汽轮机低压缸通流部分进行了改造。改造后的性能测试表明,低压缸通流效率达到了84.73%,煤耗率降低了18.42g/(kW.h),达到了机组节能降耗预期的效果。Adopting 3 -dimentional flow field design method, a modernizing retrofit of the flow passage for low- pressure cylinder of one 100 MW steam turbine in a power plant has been carried out under prerequisite of reserving the original low - pressure cylinder and the main shaft. The performance test shows that the through flow efficiency of the low - pressure cylinder after retrofit reached 84.73%, the coal consumption rate decreased by 18.42 g/kW · h, obtaining expected effectiveness of energy - saving and consumption - lowering for the unit.
