Applications of absorption heat exchangers for kinds of waste heat recovery systems.

Absorption Heat Exchanger (AHE) is a kind of new heat exchange concept put forward in recent years, by which un-matching heat transfer processes could be realized. Kinds of applications of the AHEs for industries waste heat recovery are introduced in this paper, including condensing heat recovery in CHP plant, long distance heat transportation system, low grade waste heat recovery system in steel plants and fast cooling systems in beverage production process. Real projects for the above typical applications are introduced, including waste heat recovery in Datong First CHP plant, Taiyuan Gujiao CHP plant, Qianxi steel plants and so on. The energy consumption results are shown for each project. The suitable application system structures of AHEs are discussed finally, and then the design principle of using AHEs in different systems is given.
