PURPOSE: A roaster for combusting pellets is provided to prevent the backflow of flame to a pellet fuel container by preventing flames from being conducted out of the periphery of a combustion container by a combustion flame guide container. CONSTITUTION: A roaster for combusting pellets comprises a combustion container(100) and a combustion flame guide peripheral sill(200). The combustion flame guide peripheral sill is formed in the inner peripheral surface of a combustion unit of the combustion container. The flame of pellets(400) combusted in the combustion unit bumps against the combustion flame guide peripheral sill to form vortex together with ascending flame at the center of the combustion unit. Accordingly, the pellets of the combustion unit are combusted again. |
