摘要
邹县电厂4号机组进行了DCS、DEH、发电机增容及汽轮机通流改造,汽轮机通流改造采用了三维粘性计算,设计使用了国际上最先进的子午收缩型调节级和弯扭马刀叶片及DEVA自润滑技术,使机组的经济性和可靠性得到有效改善。
Zhou Country Power Plant's generating set No.4 a retrofit of its DCS, DEH, of the generator for a capacity increase and for a better steam turbine's flow passage. Retrofit design work included 3dimensional viscid flow calculation of the flow passage, the use of a meridional contracting type governing stage, back bent twisted blades as well as the application of the DEVA selflubricating technique; all for the purpose of effectively making the set operate more economic and reliable.
