摘要

国电宿迁热电有限公司2×135MW机组投产后

汽轮机运行高压缸排汽(高排)压力和温度远高于设计值。通过大修前诊断试验分析及大修检查

找出了造成汽轮机高排压力和温度偏高的原因。对此

经过大修处理

汽轮机高排压力约下降0.13MPa

温度约下降14℃

汽轮机效率明显提高。

Abstract

After putting 2×135 MW units of Guodian Suqian Thermal Power Co Ltd into operation

the exhaust steam pressure and temperature from the high-pressure cylinder in operation of the said turbines is more far higher than the designed value. Through diagnosis and analysis before major repair and inspection during the time of major repair

the causes leading to high exhaust steam pressure and temperature from high-pressure cylinder of said turbines have been found out. Through treatment in the major repair

the exhaust steam pressure from the high-pressure cylinder has been decreased about 0.13 MPa

the exhaust steam temperature from the high-pressure cylinder being lowered about 14 ℃

substantially enhancing the efficiency of said turbines.
