摘要

超超临界1 000 MW机组的调峰能力与机组的配汽方式有重要关系

并且直接影响电网的安全性和经济性。介绍了大型机组配汽方式如喷嘴调节、节流调节、滑压调节的适用范围。对典型的超超临界1 000 MW机组的配汽方式的设计特点进行了比较分析。

Abstract

The peak-regulating ability of ultra-supercritical 1 000 MW unit has important relationship with the steam-distributing mode of said unit

and affecting directly the safety and economic efficiency of power grid.The steam distribution modes of large-capacity units

such as the suitable range of nozzle governing

throttle governing

and slide-pressure governing have been presented

the design features of steam distribution mode for typical ultra-supercritical 1 000 MW units being compared and analysed.
