Abstract
It is necessary to get basic knowledge that contributes the high co-firing rate use of the woody biomass for CO_2 reduction. In this study, the single-firing characteristics using a cedar as a woody biomass with a pulverized coal fired burner was compared with that of coals by a coal combustion test facility. The NO_x concentration at the exit of furnace in the single-firing a cedar became very lower than that of coal firing. The combustion efficiency of cedar was extremely higher than that of coal. The combustion process of a cedar near the burner was different from that of coal greatly. The ignition of pulverized cedar was easily in the cold state without pre-heating or assistant fuel.
