Performance Demonstration of Gasification and Power Generation from Woody Biomass

A distributed type small-scale gasification and power generation system using a solid waste is devel-oped. In this system, tar and soot components in the pyrolysis gas produced from a gasifier are reformed into gaseous components by using steam and air or oxygen. The reformed gas is introduced into an internal combustion diesel engine as a fuel gas for power generation.In this research, in order to investigate the optimum gasification conditions for woody biomass, three cases were compared by measuring concentrations of inflammable gases, tar and dust in the pyrolysis and reformed gases together with power generation efficiency.The first was the case when steam was supplied into the reformer, the second was the case when steam was supplied into the gasifier, and the last was the case when oxygen was supplied into the reformer.
