Abstract
Abstract This invention comprises a smokeless, highly efficient incinerator which is economical to manufacture and is particularly adapted for burning out steel barrels to clean the same for reuse. An elongated, cylindrical steel chamber is supported horizontally and defines a passageway through which the empty steel barrels are passed. A conveyer which is driven in any suitable manner is provided for carrying the barrels through the chamber at a predetermined speed to enable them to completely burn out. Gas jets are provided for starting the fire within the chamber, and an alternating series of oil nozzles spray oil into the chamber to keep the fire burning. Novel means in the form of an adjustable air nozzle array is arranged to direct the air partly into the chamber as required to provide a recirculating action of the flame pattern and a fire of relatively low temperature. The cylindrical chamber is provided with an open slot along the full length of its upper surface over and through which the air stream is directed by a plurality of nozzles spaced along the length of the cylinder. By adjusting the air streams partly into or out of the cylinder the flame may be kept clean and smoke-free. Sensors are provided to monitor combustion conditions and to actuate the various adjustable control devices hereinafter described and thus to stabilize and control combustion for smoke-free operation of the device. Air curtains are provided at each end of the chamber so that the barrels may enter and leave the chamber with a minimum of smoke emission from these openings. An air lock could be provided with double doors at the entrance and exit openings to eliminate smoke emission and to minimize disturbance of the combustion process within the chamber.
