摘　　要：目前双机回热系统回热式小汽轮机配置有变转速和定转速2种方案,文章基于某百万二次再热双机回热机组,对回热式小汽轮机采用不同配置方案的回热系统差异、机组整体经济性、关键设备选型进行了分析对比。可为后续双机回热系统设计提供一定的技术支撑。The current dual-unit regenerative systems are equipped with two options for the regenerative small steam turbine configuration:variable speed and fixed speed.This paper,based on a one-million-kilowatt dual-unit regenerative unit with secondary reheat,conducts an analytical comparison of the differences in regenerative systems,the overall economic performance of the unit,and the selection of key equipment for the regenerative small steam turbine under different configuration options.This can provide certain technical support for the subsequent design of dual-unit regenerative system.

关 键 词：双机回热系统 配置方案 关键设备 经济性
