An apparatus for carrying out various methods of material incineration includes an elongated combustion chamber housing a continuous conveyor belt supported beneath infrared heating units, air flow means to the combustion chamber and to the heating units to supply needed oxygen for cooling the heating units, a gas discharge system connected with the inlet end of the combustion chamber for counterflow of combustion gases, means for discharging the treated material at the end of the combustion chamber, and means for feeding the material to be treated into the combustion chamber. In a specific form of the system for sewage sludge treatment, the feed system includes means for grinding the sewage sludge and for pre-heating it to drive off moisture and fragment the particles. In the form of the system used for carbon activation and regeneration, a steam supply system is coupled with the discharge end of the combustion chamber to provide a steam atmosphere and the infrared lamps are isolated from the combustion chamber by quartz panes to permit cooling air flow around the lamps without flow into the combustion chamber.

A method for processing of sewage sludge from wastewater treating plants and the initial activation and regeneration of activated carbon granules or powder used for adsorption in wastewater treatment and the like. The method is carried out by supporting the combustible material in an enclosure, directing infrared radiation on the material, and controlling the atmosphere in the enclosure around the material for purposes of controlling the oxidation process initiated by the heat from the infrared radiation. In a more specific form the method includes a step of counterflowing combustion gases over the combustible material to supplement the infrared heat. The combustion chamber of the enclosure is operated at a slight vacuum to minimize escape of noxious odors. In practicing the method with sewage sludge, the sludge is first pre-dried and fragmented before introducing it into the enclosure. In the enclosure the sludge is burned by the combined heat of the infrared and counterflowing combustion gases to incinerate all combustible material in the sludge.
