摘要
根据某电厂200MW 间接空冷汽轮机的当地气候条件及多年的典型气温,确定设计背压为10.79kPa,夏季满发背压为30.7kPa,持续运行的最大背压为34.3 kPa,阻塞背压为5.4kPa。采用当代先进技术研制一只"658 mm 专用空冷末级叶片"是非常必要的。658mm 末级叶片的开发成功是一只完全自主开发的"专用空冷叶片",首次已在某电厂优化型空冷供热200 MW 汽轮机上使用,于2003年6月1日投入商业运行,各项性能指标均达到了设计要求。
Base on the second thermo-eletric plant 200MW indirect air cooling steam turbine of Tai Yuan City of Shah Xi Province,climate and specific air temperature,confirm the design pressure is 10.79KPa,summer rating power pressure is 30.7KPa,Max.pressure is 34.3KPa,obstruct pressure is 5.4KPa.Use a new advanced 658mm air cooling blade is needed, 658mm last blade is a self-determination arbitrary air cooling blade,first use on one of thermo-eletric plant 200MW air cooling steam turbine,2003-6-1 enter business run,each performance reach the design.
