Abstract
An incineration system utilizes a circular cross-section pyrolysis chamber in which waste materials are gasified. A flat cast iron hearth serves as the floor of the pyrolysis chamber and has a number of small holes which are raised above the general hearth level by a number of nipples. The bolted front head of the chamber has a vertically movable front door. When raised, the hinged door assembly may be opened by unscrewing a pair of locking mechanisms which seal the door to a vertically movable frame. Ash removal may be accomplished by partially raising the entire structure, rather than opening the door. The ash ram is rectangular, covers a substantial area of the chamber floor when extended, and utilizes a unique cable and cylinder ram moving system. An air plenum above the chamber also acts as a platform, allowing inspection and maintenance to take place on top of the chamber. Gasified waste material leaving the pyrolysis chamber is ignited and burned in a thermal reactor utilizing reverse rotation and forced air combustion to effectively mix and burn the waste material after gasification.
