Abstract

Biomass Gasification has emerged as the most promising technology for the decentralized heat and power applications. The prediction of the performance of biomass blends in gasifiers is an important area of study for the implementation of this technology in various applications, relevant to remote villages. This paper presents the theoretical and experimental studies conducted on a 50 kWth downdraft biomass gasifier with various combinations of the biomass materials such as wood, coconut shell, rubber seed kernel and coir pith, which are abundantly available in the villages of South India. Two zone kinetic equilibrium model is used for the theoretical simulation. The influence of equivalence ratio and composition of feedstock blends on the quality of producer gas and the conversion efficiency of gasifier were studied, and reported. The experimental and theoretical studies show that the effective utilization of biomass materials as blends can meet the rural energy demand.
