This paper carries out a performance analysis based on
the first and second laws of thermodynamics for heat recovery vapor
generator (HRVG) of ammoniawater mixture when the heat source is
lowtemperature energy in the form of sensible heat. In the analysis,
effects of the ammonia mass concentration and mass flow ratio of the
binary mixture are investigated on the system performance including
the effectiveness of heat transfer, entropy generation, and exergy
efficiency. The results show that the ammonia concentration and the
mass flow ratio of the mixture have significant effects on the system
performance of HRVG.
