【摘要】 针对某175MW燃气-蒸汽联合循环机组中余热锅炉和蒸汽轮机调试存在的问题进行分析,提出改进意见。实践表明我国在联合循环机组除燃气轮机以外设备的制造、安装、设计、调试和大型机组机电成套配置方面达到一定的水平。指出燃气-蒸汽联合循环机组在我国具有广泛的发展前景,尽快缩短我国在燃气轮机及其配套产品方面与国外先进国家的差距。更多还原

【Abstract】 This paper analyzed the problems existing in the commissioning of heat recovery boiler and steam turbine in a175MW gas-steam combined cycle generating unit and put forward the improvement proposals.The practice showed that the obvious effects had been achieved.This reflects that the manufacture,installation,design,commissioning and complete set layout etc.fields of large size gas-steam combined cycle generating unit except gas turbine in China have reached a certain level.This paper also indi-cates that there is a broad developmental prospect in China for gas-steam combined cycle generating unit,the gaps in the gas turbine and its complete products between China and foreign advanced countries should be narrowed as soon as possible.更多还原
