For the realisation of a decarbonised society and the enhancement of disaster resilience, wood gasification combined heat and power (CHP) as a decentralised power source is promising in terms of its high power-generation efficiency and overall efficiency, despite its small scale. The use of cedar as a wood fuel for CHP has been a challenge due to its inorganic components that causes clinker formation. It is also necessary to clarify the fusibility of ash in co-gasification with various biomasses to ensure stable use of wood fuel. In this study, the possibility of inhibition of clinker formation was investigated by evaluating the fusibility of binary blended biomass ashes of cedar and other biomasses using thermogravimetry/differential thermal analysis, ash fusion test, and multi-component equilibrium calculations.
