燃气-蒸汽联合循环供热调峰机组热态启动优化

Gas-steam combined circulating heat and peak-load unit hot start improvement

为提高6FA联合循环供热调峰机组热态启动的经济性,通过投用减温减压装置,将不符合汽轮机冲转参数的蒸汽能量利用起来,用于对外供热。经济性分析表明,优化后可有效降低机组的运行成本。

To increase the economical efficiency of 6FA combined circulating heat and peak-load unit hot start,steam that unqualified for stream turbine stroke was utilized for heat supplying by applied desuperheating and reducing devise. Economical efficiency analysis indicated that unit operation cost was reduced after improvement.
