ICOPE-15-C051 The Technology Development of DongFang 1000MW ultra-supercritical steam turbine

抄録

The technical characteristics of the new DTC (Dongfang turbine Co.,Ltd) high efficiency 1000MW ultra-supercritical steam turbine with 1200mm end rotor blade are described in this paper. The detailed optimizing technology of the thermal system, flow passage, structure design and operation mode is illustrated and the corresponding application conditions of these technology are presented as well. The technical index and research and development process of the new DTC high efficiency 1000MW ultra-supercritical steam turbine are also introduced. The heat rate prediction of the unit will reduce 6% by 2022 in order to make the coal-fired unit cleaner and more efficient and then make great contribution to the energy conservation and emissions reduction of the world.
