摘　　要：哈汽为巴西卡迪奥塔火电厂设计的350MW汽轮机,其转速为3600r/min,高中压缸采用合缸结构,低压缸采用1017mm末级长叶片双分流结构。机组通流部分进行全三维优化设计,使机组具有较高的运行效率。文中重点介绍了巴西350MW机组高中压缸及低压缸通流部分的设计特点。The rotating speed of 350MW steam turbine is 3600r/min designed for power plant in Brazil. Combined cylinder structure is applied in the high and intermediate pressure cylinders. Double dividing structure with the lO17mm last stage blade is applied in the low pressure cylinder. Full three dimension optimization design of flow passage is carried out for increasing the unit operation efficiency.
