基于吸收式换热机组的新型供热系统研究

Research on new heating system based on absorption heat exchanger unit

提出一种新型供热系统,通过吸收式换热机组与传统集中供热相结合的方式深挖燃煤热电厂的节能潜力。首先在热网上利用高温热水和燃气驱动吸收式换热机组来降低一次网回水温度,其次在热电厂中构建与蒸汽型吸收式换热机组串联的梯级加热流程,实现冷凝器余热的高效回收,显著了提高热电厂的供热能力。

This paper proposes a new type of heating system,which deeply explores the energy saving potential of coal-fired thermal power plants by combining absorption heat exchange units with traditional central heating.Firstly,the absorption heat exchanger unit is driven by high temperature hot water or gas in the heat network to reduce the temperature of the return water.Secondly,a cascade heating process in series with the absorption heat exchange unit is constructed in the thermal power plant to realize the efficient recovery of the waste heat of the condenser and significantly improve the heating capacity of the thermal power plant.
