Use of LP steam of HRSG for absorption cooling system and its role in improvement of power plant efficiency

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 chillersused in residential space cooling of power plant. Parametric study indicates the effects of different parameters, such as steamto 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 theperformance of present power plant. Also, the relative advantage of using absorption cooling over mechanical vaporcompression (MVC) cooling in combined cycle power plant and its role in improvement of power plant efficiency is demonstrated
