摘要
上汽国产引进超临界600MW机组存在调节级喷嘴面积偏大的问题,调节级面积偏大造成调节级效率偏低、组热耗偏高,结合机组大修,通过调节级喷嘴面积核算,合理对调节级喷嘴进行改造,提高机组效率,降低机组能耗。
Regulating stage nozzle area slants big problems of SAIC imported 600MW supercritical unit, regulating stage regulating stage large caused by low efficiency, high consumption group heat, combined with the unit overhaul, by regulating stage nozzle area calculation, reasonable carries on the transformation to the regulating stage nozzle, improve unit efficiency, reducethe energy consumption of the unit.
