摘　　要：为了降低燃煤电厂的能耗,该文提出了一种基于吸收式热泵的循环水余热利用技术,提取发电机组的循环水余热用于城市供暖,在热电厂内设置溴化锂吸收式热泵站,利用机组循环冷却水作为热泵的热源水,提取余热加热热网水,从而显著提升热电厂的供热能力及热效率,进一步降低综合供电煤耗,实现节能减排的目的。To reduct energy consumption of coal-fired power plant, a kind of waste heat recovery technology of circulating water based on heat pump is applied. Lithium-Bromide absorption-type heat pump station is located in thermal power plant, circulating water is utilized as heat source water of heat pump to heat water of heat-supply network. The application of heat pump technology in thermal power plant can significantly improve heat-supply capability and heat efficiency, reduce net coal consumption, and implement the target of energy-saving and environment protection.
