Abstract

A primary air duct (3) leads into the pyrolysis chamber (1). A flue gas duct (5) connects the bottom end of the pyrolysis chamber with one end of the elongated horizontal combustion chamber (4). A suction fan (7) is connected to the other end of the combustion chamber which is fed by a secondary air duct (6). The secondary air duct opens into the flue gas duct which opens radially into the combustion chamber. The combustion chamber has an axial inner ridge (9) opposite the flue gas duct.
