摘　　要：我国1 000 MW超超临界机组主要有上汽-SIEMENS机型、东汽-日立机型及哈汽-东芝机型。超超临界机组在低负荷时能滑压运行,故有良好的低负荷运行性能,其主汽压力可随着负荷的降低而降低。1 000 MW超超临界机组锅炉一般采用八角双切圆燃烧或前后墙对冲燃烧方式,主要采用Π型布置和塔式布置。汽轮发电机组采用四缸四排汽,单轴布置。The 1 000 MW extra - supereritical units in China are mainly Shanghai Turbine Manufactured - Siemens, Dongfang Turbine Manufactured - Hitachi and Harbin Turbine Manufactured - Toshiba models. The units can be operated under sliding pressure and have good low load performance. Their main steam pressure can be reduced with reduction of the load. The 1 000 MW boilers adopt normally the octagonal double - tangential circular combustion or front - rear - wall symmetrical combustion mode and mainly take ＂P - shape＂ or tower shape configuration. The turbine - generator units are mainly 4 - casing, 4 - exhausting, single shaft arrangement.
