摘　　要：改进型200MW汽轮机及大型空冷汽轮机的不断投产,为200MW间接空冷汽轮机改造提供了技术储备。末级叶片的优化设计是发展空冷机组重要条件之一,正是由于选择了合适的末级叶片,对丰镇电厂的机组改造取得了成功。The modified 200MW steam turbines and large-scale air-cooling turbines are put into production continuously, which provides technical preparation for modification of 200MW indirect air-cooling steam turbines. The optimum design for the last stage blade is one of the most important conditions to develop air-cooling units. The successful modification in feng- zhen power plant is mainly owing to the proper choosing of the last stage blade.
