摘　　要：通过对传统式汽封与蜂窝式汽封的比较,论述了600MW汽轮机组采用蜂窝式汽封改造能够有效减少各级漏气量,提高汽轮机三缸效率、降低机组的热耗,并取得了良好的经济效益。Comparing traditional steam seals with honeycomb steam seals, the technical transformations of 600 MW steam turbine units adopting honeycomb steam seals were discussed in the paper. Remarkable achievements have being obtained by means of the technical transformations mentioned above, such as the reduction of air leakage from all levels, the improvement of three-cylinder efficiency for steam turbine units and the drop of heat consumption for units. All in all, the considerable economic benefits have being made.
