GASIFICATION PERFORMANCE OF VARIOUS SOLID WASTES USING A PYROLYSIS/REFORMING GASIFICATION PROCESS

摘要

A distributed type small-scale gasification and power generation system using solid wastes is developed.In this system, tar and soot components in the pyrolysis gas produced from a pyrolyzer are reformed intogaseous components by using steam and air or oxygen. The reformed gas is introduced into an internalcombustion diesel engine as a fuel gas for power generation.In this research, in order to investigate the gasification conditions for woody biomass, three cases werecompared by measuring concentrations of inflammable gases, tar and dust in the pyrolysis and reformedgases together with power generation efficiency.The first was the case where steam was supplied into the reformer, the second was the case where steamwas supplied into the pyrolyzer, and the last was the case where oxygen was supplied into the reformer.
