Özet

In advanced absorption power cycles (AAPCs), a jet ejector is installed at the absorber inlet and serves for two main functions; it assists pressure recovery, and improves the mixing between the weak solution and the vapour coming from the turbine. These effects enhance the absorption of the vapour into the solution resulting in a better performing power cycle. The influence of the jet ejector on the energy and exergy efficiencies of an AAPC is evaluated, and the thermodynamic efficiencies of the AAPC are compared to those of conventional absorption power cycle (APCS) using three different working fluids, namely ammonia-water solution (NH3-H2O), lithium bromidewater solution (LiBr-H2O), and lithium chloride-water solution (LiCl-H2O). Five cases are studied that represents the improvement in the AAPCS efficiencies as results of jet ejector integration in the cycle. Results of parametric studies depict that LiCl-H2O exhibits the highest energy and exergy efficiencies used in AAPC.
