摘　　要：提出利用热泵冷水和供热回水冷却冷凝锅炉中的烟气,以回收水份和水蒸汽潜热,采用活性炭吸附、除碳器和离子交换器对冷凝锅炉凝水进行处理后,可达到注汽给水标准,组成闭式程氏循环。以综合效益最好为目标,运用年总费用法和层次分析法,在满足给定的全年热电冷负荷需求的基础上优化系统各设备的运行,合理确定燃气轮机热电冷联产系统的规模与组成形式。通过实例验证了方法的有效性。In the first step, cold water coming from a heat pump and return water from a heat delivery system are taken to be used to cool flue gas in a condensing heater to recover water and latent heat contained in the vapour. Following treatment with active carbon as absorbent, with carbon separator and ion exchangers, the condensate of a condensing heater can be made fit to be used as feed water for steam injection. Thus a closed Chen's cycle can be formed. In a second step, with maximal proceeds as objective, the total annual operation expenditure and AHP analyzing method is used for considering optimal operation of all the cycle's components, under the prerequisite that the annual requirements of power, heating and cooling are met. Rational capacity of the CHP system and its build-up is also taken into consideration. The effectiveness of the method is ascertained by a practical example.
