Abstract:

Heat pump circulating technology and power and heat plant circulating water waste heat utilization was introduced. Absorption pump could use cold source heat loss for urban heat supply. System solved existing problems of power and heat plant centralized heat supply. Take a thermal power plant’s 4×200MW unit in Hebei Province as example, after applied absorption heat pump, heat supply increased by 300GJ/h, annual coal consumption reduced by 34000t. Emission of CO2,SO2, NOx and flow gas effectively reduced. Social benefits and economic benefits are outstanding.
