摘　　要：二次中间再热机组相对一次再热机组经济性提高约1.5%,文章详细论述了东方660 MW二次再热超超临界汽轮机的热力设计特点,对促进我国火力发电技术进步和节能减排具有现实意义,为我国大容量燃煤机组发展提供了示范,为更高参数700℃等级燃煤电站的实现具有示范和技术储备的作用。The thermal efficienc.y of double-reheat cycle steam turbine will increase 1.5% than the single-reheat cycle. Thermal design features of 660 MW double-reheat cycle ultra-supercritical steam turbine are detailedly discussed in this paper, the double- reheat technology is endowed with important significance for improving the thermal power generating technology and energy conser- vation, a model for the development of China ＂s large-capacity coal-fired power plant is provided by double-reheat technology, and this technology is also used as demonstration and technical reserves for the achievement of the higher parameter （700 ℃） coalfired power plant.
