Design of lab-scale downdraft gasifier for biomass gasification

Abstract

Biomass gasification is a cost effective, efficient and eco-friendly source of alternate energy. The gasification efficiency depends on several parameters like equivalence ratio, gasification agent, gasifier configuration, etc. Downdraft gasifier is a most suitable gasifier for biomass gasification due to inherent advantages like feedstock flexibility, better process control, low tar formation, and simple construction. The aim of this paper is to conduct a comparative study of different configurations and design a 5kW lab scale throat less biomass gasifier using an analytical method.
