Modelling, sensitivity and exergy analysis of triple-pressure heat recovery steam generator

Abstract

Related to the increasing demand for environmental pollution and electrical energy, combined cycle power plants (CCPP) are increasingly important. So, It is necessary that increasing the performance of power plants, reducing carbon emissions and rising energy production. Any change related to the heat recovery steam generator design is important for essential components of the CCPP because of directly affects the performance of it. In this study, it has explained that the modelling, sensitivity and exergy analysis of a Heat Recovery Steam Generator (HRSG) in a CCPP. In the analyzes, three-pressure HRSG was modelled with the Aspen Plus simulation program. In addition to, sensitivity analyzes were done and evaluated. Also, energy and exergy analyzes were done for each component in the CCPP.
