摘　　要：首钢迁钢2X50MW燃气-蒸汽联合循环（CCPP）发电工程结合国内机组运行情况，对燃气-蒸汽联合循环发电机组系统做了以下改进：余热锅炉采用三压锅炉，余热锅炉主蒸汽参数采用次高压高温蒸汽；蒸汽轮机采用全周进汽快速启动高温次高压汽轮机。新技术的应用，余热锅炉热效率提高5％，联合循环发电机组综合效率提高9．6％，年增加发电效益2864万元。2X50 MW fuel gas-steam combined cycle power project of Shougang Qiangang steel plant in combination with internal operation cites, the following improvements on the system of CCPP：HRSG adopted three pressure boiler, the parameter of main steam is sub-high pressure and high temperature; steam turbine using uniform-admission steam quick start times of high temperature sub-high pressure steam turbine. The application of the new technology, the heat efficiency of HRSG increased 5%, the comprehensive efficiency of combined cycle power increased 9.6%, the power benefit increased 28 640 000 yuan/year
