抽汽凝汽式汽轮机通流部分改造及效益分析

Renovation of Flow Path of Extraction Condensing Steam Turbine and Benefit Analysis

对国产200 MW三缸两排汽抽汽凝汽式汽轮机,采用当前先进的准四维/全四维技术对通流部分进行改造,其性能优于目前国内200 MW三缸三排汽凝汽式汽轮机通流部分改造采用的准三维/全三维技术。该成果在国内电力行业处于领先水平,对同类机组增容降耗改造有重要的示范意义和推广价值。

The advanced quasi-4D/full 4D technology was adopted condensing steam turbine with 3 casings and dual exhausts of 200 technology is better than the existing quasi-3D/full 3D technology turbine with 3 casings and three exhausts of 200 MW units. This electric power industry and provides reference for upgrading of unit similar units. to retrofit the flow path of extraction MW unit in China the first time. This used in retrofitting flow path of steam technology takes the lead in domestic and reduction of consumption for other similar units.
