Abstract

Biomass gasification procedure is a very complex process and it is influenced by many physical and chemical factors such as biomass gasification temperature and gasifier type. Thermodynamic assessment methodology based on the energy and exergy analysis can be used to evaluate the system performance and environmental impacts. In this paper, thermodynamic analysis of the biomass gasification system is given for the whole system and its components. The parametric studies reveal the effects of design and operating indicators on the exergy efficiency and exergy destruction rate. The result shows that the gasification temperatures for the biomass gasification system change significantly with the type of the gasifying medium.
