摘　　要：以国网能源神头第二发电厂500 MW汽轮机组近年来进行的汽轮机汽封、通流间隙、疏放水系统、低加疏水系统、胶球系统、冷却塔虹吸罩等节能技术改造项目为例,分析了其存在的问题,并进行了改造方案实施及改造前后的效果评价,改造方案实施后,提高了汽轮机组的节能指标,改善了机组的经济性能。Some energy-saving reformation projects were carried out in 500 MW steam turbine unit in State Grid Energy Shentou Power Plant, including the reformation in gas seal, flow passage clearance, water drainage system, low pressure drainage system, rubber ball system, cooling tower siphon cover, etc.. The problems before the reformation were analyzed and effect evaluations were done after the reformation. The result shows that the energy-efficient indicator is raised and the economic performance of the unit is improved.
