Abstract :
In this paper, for the actual case study, the portion of generated low pressure (LP) steam of heat recovery steam generator (HRSG) is investigated for the absorption chillers used in residential space cooling of power plant. Parametric study indicates the effects of different parameters, such as steam to gas mass flow rate ratio, fraction of steam extraction from the exhaust of LP line in HRSG for the generator of absorption chillers and inlet LP and HP steam turbine temperature on the performance of present power plant. Also, the relative advantage of using absorption cooling over mechanical vapor compression (MVC) cooling in combined cycle power plant and its role in improvement of power plant efficiency is demonstrated.
