摘要
根据燃煤电厂热电联产集中供热中存在低温余热利用率较低的现状,分别探讨了汽轮机低真空运行供热技术、"NCB"新型供热机组技术、压缩式热泵回收乏汽余热技术、吸收热泵回收乏汽余热技术的特点和适用范围。得出溴化锂吸收热泵回收乏汽余热技术具有适用范围广、节能效果显著等特点,适合在热电联产集中供热机组推广应用。
According to the current situation of low temperature waste heat utilization rate low in cogeneration dis- trict heating of coal fired power plant, respectively discusses steam turbine low vacuum operation heating technology, ＂NCB＂ model of heating unit technology, compression type heat pump recovery of steam exhaust waste heat technology, the characteristics and application scope of absorption heat pump recovery of steam exhaust waste heat technology. Ob- tains the lithium bromide absorption heat pump for recovering steam exhaust waste heat technology has wide application range, obvious energy saving effect and other characteristics, it is suitable for popularization and application in district heating by cogeneration unit.
