100MW汽轮机低压缸通流部分改造
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。
Abstract
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.
