A15 Examination of a Stirling Engine Power Generation System by Woody Biomass Fuel Using a Firewood Boiler

Abstract

Woody Biomass is defined as a new energy and desired to utilize an energy source beneficially. The authors present a power generation system constructed by a firewood boiler and a Stirling engine generator, The firewood boiler using gasification combustion has a maximum incineration capacity of 20kg/h and a power consumption of 400W. The Stirling engine generator is built up as a 2 piston type engine with driving mechanism including a PM synchronous generator. It is installed in a secondary combustion chamber of the firewood boiler and heated by combustion gas. This paper describes the examination results of the system using a firewood of Japanese oak as fuel. The power generation of 534W and the heat supply capacity of 33.6kW are obtained.
