A vertical shaft furnace for the pyrolysis of pelletized refuse, having a hearth in the base provided with a refuse bed support structure comprising a plurality of cooled, refractory support members, extending radially inward from the wall toward the axis of the hearth. The support structure is characterized by having a plurality of peripheral spaces extending through side structure and converging in the downward direction, each of the peripheral spaces being formed, at least in part, by the side wall surfaces of adjacent support members and the inside surface of the hearth.
