660-1350MW High efficient ultra-supercritical steam turbine reheat main gas valve body

According to the deputy chief engineer of Shanghai Honggang Wu Tieming, which is the first successfully developed high temperature 620 660-1260MW and efficient ultra-supercritical steam turbine unit accessory products in China. At present, the ordinary coal-fired units consumed an average of 330 grams per kilowatt, even a 600 heat- resistant coal-fired units consumed 278 g, while Shanghai Honggang is the first to enter the era of high temperature 620 ° C heat resistant, the coal consumption is only 250 g.
