PURPOSE: A pyrolysis furnace is provided to supply the pyrolyized gas from the organic waste lump by digging the organic waste lump with a first digging scraper. CONSTITUTION: A pyrolysis furnace comprises cylindrical chambers(30, 40) and auger shafts(36, 46). The center of auger shaft is located at the lower side in a vertical direction from the center of the cylindrical chamber. A radial inner ends of spiral part(37, 47) is circumscribed to the auger shaft. The outer diameter of spiral external end is shorter than the inner diameter of the chamber. The radial external end of the spiral part is stretched over the entire longitudinal direction of the auger shaft and inscribed in the inner circumference of the lower part of the chamber.
