热电厂热泵技术乏汽利用的介绍及应用

Introduction and Application for the Heat Pump Exhaust Steam Utilization Technology of Thermal Power Plant

热泵是一种利用高位能使热量从低位热源流向高位热源的装置。热泵可以从低温热源中提取热量用于供热。热泵的供热量远远大于它所消耗的机械能,热泵技术是一种低温余热利用的节能技术。热电厂采用了吸收式热泵利用汽轮机乏汽余热提高热网供水温度,从而提高热电厂供热能力、电厂运行经济性,节约能源,保护环境。

The heat pump is a device that using high level to make the heat from the low level flow to high level heat. Heat pump can extract heat from a low temperature heat source for heating. The supplying heat of heat pump is much larger than it consumes mechanical energy, heat pump technology is an energy-saving technology of low-temperature waste heat utilization. Thermal power plant uses the absorption heat, which uses steam turbine exhaust steam waste heat to increase heating network water temperature, thereby increasing heat capacity and operation economy of thermal power plant, saving energy and protecting environment.
