Jan. 18, 1934, No. 1798. [Class 51 (i)] Sewage, garbage or the like is treated by passing it downwardly through a furnace 6 comprising superposed hearths 21 ... 30, Fig. 1, and a rotary vertical shaft 15 with stirring arms 20 which move the material under treatment through successive drying, burning and cooling zones while subjected to streams of air and gases, the resulting gases after passage through the zones being elevated in temperature before escaping to the atmosphere to eliminate noxious odours. Combustion of the material is completed on the hearths 27, 28 and the ashes pass through sealed openings 31 to the hearths 29, 30 and are finally discharged at 34. The gases leaving the furnace are subjected to the cooling action of water sprayed by a nozzle 36 in the condenser 7 and are then forced by a fan 39 over the ashes on the hearths 29, 30 for cooling purposes and to a combustion chamber 8 provided with an oil burner 41 or other source of heat to deodorize the gases. After leaving the combustion chamber 8 the gases pass over a recuperator 46 in which air supplied by a fan 45 is heated and then escape to the atmosphere. Heated air passing from the recuperator is delivered through dampercontrolled passages 48 to the lower drying and burning zones. Additional heat may be supplied to the furnace as for example by a burner 50. To stimulate combustion on the hearths 27, 28, cooling-air from the rabble shaft and arms may be delivered from nozzles provided on the rabble arms. According to a modification, the cooling air passing through the rabble shaft may be led through a pipe passing through the outlet flue for the deodorized gases and thence to the burning zones of the furnace and to the outlet flue. Fig. 4 shows a further modification in which the gases leaving the drying and burning zones are led through superposed chambers provided with baffles 132, 133 where they are treated by hot gases from burners 129. In further modifications a separate furnace is provided below or adjacent to the main furnace for burning waste material the gases from which are caused to mix with the gases leaving the upper part of the main furnace and may also be led to various hearths of the incinerator.
