摘要
介绍了国产300 MW等级纯凝机组再热蒸汽及主蒸汽管道抽汽改造方案,通过理论计算与试验,得到每台机组再热冷、热段不同负荷工况抽汽量,表明300 MW等级纯凝机组通过多汽源联合工业供汽改造,可实现单机最大供热170t/h、1.5 MPa的工业蒸汽,为其他300 MW等级阿尔斯通、东方汽轮机类型纯凝机组供热改造提供经验。
This paper introduced the steam extraction transformation scheme of reheat steam and main steam lines for a homemade 300 MW condensing power unit,and through theoretical calculation and experiment,it acquired the extraction flows at low and high temperature parts of reheating pipe under different load conditions for every unit. The study showed that through multi-source industrial steam supply transformation of 300 MW condensing power unit,it realized the maximum heat supply of 1. 5 MPa industrial steam per unit up to 170 t/h,which provided a reference for the heating transformations of other 300 MW condensing power units,such as Alstom and Dongfang.
