Abstract
The purpose of this study was to understand the basic combustion characteristics of a wood pellet gasified combustor using secondary air swirl flow. The secondary air swirl flow can increase enthalpy and temperature in secondary combustion chamber because it enhances the mixing of air and combustible gas and it improves the combustion state. Two types of air injection holes (slit, circle) were examined. As a result of this experiment, it was revealed that the enthalpy and temperature were higher than that of previous experiment because its combustion state was improved by secondary air swirl flow.
