Experimental investigation on gasification parameters of a co current flow gasifier fed with a woody and a non woody loose biomass

Abstract

Biomass is one of the renewable energy resources and it is a manifestation of solar energy Biomass gasification is a set of thermochemical reactions by which the solid biomass is converted to a gaseous fuel called producer gas Although wood is the widely used feedstock for gasifiers its limited availability and increasing cost have necessitated the utilization of bioresidues like rice husk shells of various nuts corn cobs etc in gasifiers The global availability of groundnut shells alone is about 11 2 MMT But bioresidues pose certain problems during gasification, thus warranting thorough investigation In the present work groundnut shells were gasified in loose form and the results were compared with that of wood gasification Besides certain parameters like pressure distribution in the gasifier, propagation of reaction zones changes in properties of bed particles during gasification etc were investigated for both biomass newline
