Heat Rate Enhancement of IGCC Power Plant Coupled with Solar thermal power plant

Abstract

Integrated gasification  combined cycle power plant (IGCC) has shown the potential of having higher operating thermal efficiency, than supercritical thermal power plants as it combines the advantages of coal gasification and combined cycle power plant. Solar thermal plant has shown great promise to augment the thermal efficiency of the fossil based power plants and reducing CO2 emissions. In this research paper, impact of integrating solar thermal power plant utilizing linear Fresnel collectors (LFC) with IGCC plant on plant heat rate has been simulated. The feed water from condenser is connected to series of LFC modules and preheated before admitting into de-aerator instead of feed water being pre-heated in feed water heater using steam from turbine extractions. The impact  of solar feed water heating on plant heat rate and plant  thermal efficiency has been evaluated over entire day.
