In Japan, large reduction of the carbon dioxide emission amount is demanded according to Paris agreement. Woody Biomass is defined as a new energy and desired to utilize an energy source beneficially. The authors present a combined heat and power system constructed by a firewood boiler and a Stirling engine generator. The firewood boiler has a maximum combustion ability of 16kg/h and is available for consecutive combustion by a kerosene burner. The Stirling engine generator is built up as a 2 piston type engine with driving mechanism including a PM synchronous generator. It is attached to the back wall of the firewood boiler and heated by combustion gas. This paper describes the design overview of the system and the examination results of the firewood. The authors burnt 14.9kg of firewood and got heat exchange of 20.9kW by warm water.
