摘　　要：提出了一种基于常规供暖模式下采用吸收式热泵吸收汽轮机做功后乏汽和汽水换热器将热网循环回水进行二次加热的新方案。以某2×300MW热电厂机组为例,对新方案进行了可行性分析,并与常规方式进行了对比,结果表明:新方案更加节能环保,供暖成本降低,效果更好。Based on the conventional heating mode,this article proposes a new method that the heating-network cycle-water is reheated by the exhausted steam of the turbine absorbed from the absorption heat pump,. Taking a 2 × 300MW thermal power plant unit as an example,the article conducts a feasibility analysis for the new program and compares with the conventional way. The results show that the new scheme is more energy--saving and environmentally friendly with lower heating costs.
