Abstract
本实用新型公开一种煤电机组结构重构及热力系统重构的燃煤发电系统，包括一台发电机和两台汽轮机，发电机串联设置在两台汽轮机之间；还包括汽包锅炉，其中过热器的出汽口通过主蒸汽管道分别与两台汽轮机的高压缸的进汽口相连接，高压缸的出汽口通过再热冷段蒸汽管道与再热器的进汽口相连接，再热器的出汽口通过再热热段蒸汽管道分别与两台汽轮机的中压缸的进汽口相连接；还包括储热系统，在主蒸汽管道或再热热段蒸汽管道上引出有过热汽管道，过热汽管道与储热系统相连接，储热系统通过疏水管道与除氧器相连接，锅炉给水管道上形成有两段加热段与储热系统相连接以加热给水。在经济条件和本质安全前提下实现煤电深度调峰、高效调节和宽负荷保效。
