摘　　要：以2台国产600 MW直接空冷亚临界机组为例,对比了高、中压缸不同形式汽封组合和间隙设置下的节能效果,结合实际提出了汽封改造间隙的设定范围,供同类型电厂汽封改造时参考。Taking two domestic 600 MW direct air-cooling subcritical units as example,the energy-saving effects of the two units under different steam seal combinations and different gap settings of HP and IP cylinders were compared. Combining with practice,the gap set range for steam seal reformation was proposed,which can be used as reference for similar power plants in steam seal reformation.
