“二拖一”燃气蒸汽联合循环机组的并汽与退汽
摘要
"二拖一"式燃气-蒸汽联合循环机组中汽轮机的并汽与退汽是2项较复杂的操作过程
操作方式不当可能会对机组造成较大的冲击。研究表明
采用主、再热蒸汽同时并汽、退汽的操作方式
负荷适应性能强
可操作性好
有利于机组的稳定运行。
Abstract
Bringing steam on and withdrawing steam from the steam turbine "two-pull-one" type gas-steam combined cycle unit are two comparatively complex operating processes
improper operating mode may result in large impulse to the said unit
practice of study on the said type of steam trubine shows that the operating mode of simultaneously bringring main steam and reheated steam on and withdrawing them from "two-pull-one" type combined cycle unit has strong suitability to load
boasting good operability
and being helpful to stabilize operation of said unit.
