摘　　要：目前,660 MW、1000 MW等级超超临界机组已相继在火电厂投产,为获得更好的经济效益,对1350 MW等级机组进行了设计与应用研究,从相关技术方案、材料、通流、末级叶片等方面确定了一系列设计方案,通过方案比选和优化设计,所研制的1350 MW机组比常规机组在进汽参数、机组效率、安全性和经济性等方面有了明显提高,为我国大型汽轮机的设计和制造提供了借鉴。At present,660 MW and 1000 MW ultra supercritical units have been put into operation one after another.In order to obtain better economic benefits,the design and application of 1350 MW units are studied.A series of design schemes are determined from the following aspects,such as related technical schemes,materials,through-flow,last stage blades and so on.Based on the scheme comparison and optimization design,it is found that the developed 1350 MW unit is obviously improved in steam inlet parameters,unit efficiency,safety and economy compared with the conventional unit,which provides reference for the design and manufacture of large steam turbines in China.
