Energy-Recuperative Biomass Integrated Gasification Power Generation System

In a biomass integrated gasification/gas turbine (BIG/GT) system, a novel configuration with external heat source using GT exhaust was proposed and evaluated. The proposed system was compared to the conventional configuration of the BIG/GT system with an internal heat source obtained by partial combustion of biomass. The system integration and evaluation were performed using a commercial process simulation tool, ASPEN Plus. The proposed system comprises energy recuperation technologies: heat, steam, and thermochemical recuperations. An improvement in the system performance was confirmed in the proposed BIG/GT system in comparison with the conventional system by means of the integration of external heating feature in gasifier using the exhaust as the heat source.
