燃气—蒸汽联合循环机组轴系布置方案的分析

Shafting Arrangement Analysis of Gas–Steam Combined Cycle Unit

为迎接西气东输和LNG(液化天然气)的输入,我国东部地区正在建设一大批大型燃气—蒸汽联合循环电厂,为了使建成后的电厂单位投资省、热效率高、投产后具有较好的效益,选择合适的燃气—蒸汽联合循环机组轴系布置方案非常重要。燃气—蒸汽联合循环机组的轴系布置方案有多轴布置方案和单轴布置方案。为此,分析两种布置方案各自的优缺点,为选择合适的联合循环机组轴系布置方案提供依据。

There are two schemes of shafting arrangement of gas–steam combined cycle unit : single shaftarrangement and multies shafts arrangement. Analyzed the merits and demerits of every arrangement. Providedthe bases for selecting the shafting arrangement of gas–steam combined cycle unit.
