The characteristic properties of the combustion of wood blended with coal or oil coke fuels has been studied. Pulverized coal or oil coke and powdered woody materials (larch) were used as the raw materials. These solid fuels were briquetted under pressure of 1 t/cm^2 at room temperature, by using a molding press. The measurement of the combustion pattern and the ignition temperatures of these solid fuels was carried out using the differential thermal analysis method. The ignition temperature of the sample from coal or oil coke alone was 345℃ for Sunagawa coal and 385℃ for oil coke, while for the larch bark and the heart wood, the ignition temperatures were 260℃ and 305℃ respectively. When the content of woody materials in the blended solid fuels was greater than 20 wt.％ for Sunagawa coal-wood fuel, 20 wt.％ for oil coke-bark fuel and 25 wt.％ for oil coke-heart wood fuel, then the ignition temperature of Sunagawa coal or oil coke fell to the same temperature of larch bark or heart wood. It was confirmed that the mild oxidation of coal and the amount of volatile matter from coals significantly affected the combustion behaviour of wood blended coal fuels.
