| Abstract: | 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. |
