| 摘 要： | 国内引进的9FA燃气-蒸汽联合循环发电机组中,大多数是"一拖一"单轴机组(燃机、汽轮机、发电机同轴布置),"二拖一"多轴机组在国内只有少数几套,而采用串联旁路、汽轮机中压缸启动则仅有1套。"二拖一"机组在我国作为调峰机组使用,启停频繁,其中并汽和解炉是启停操作过程中的技术难题。针对"二拖一"机组的技术特点和应用情况,通过对汽轮机高压缸、中压缸调节门和余热锅炉主蒸汽、再热蒸汽旁路控制原理的研究,对并汽和解炉操作过程进行了分析和探讨,较好地解决了"二拖一"联合循环机组在启停过程中汽轮机顺流不稳、主蒸汽、再热蒸汽参数匹配困难等问题。

| Abstract: | In recent years,most of the 9FA series gas-steam combined cycle power units imported into China are one-on-one single shaft unit,i.e.gas turbine,steam turbine and generator are arranged in one single shaft.Several of them are two-on-one multi-shaft unit.Only one unit is cascade bypass arrangement and steam turbine starts with intermediate pressure cylinder. two-on-one unit is used as peak load unit,it started and stopped frequently,and the steam combination and decomposition furnace are technological diffic... |
