Abstract
Abstract A portable incineration system is provided in which transportable modular units are interconnected to provide a large scale incineration system. The fly ash and other undesired particles are removed from the hot gases without developing a steam plume by reheating and drying these gases prior to exhaust. The hot water produced during fly ash removal is circulated through a suitable cooler, or used as a constant heat source, and the cooled water is recirculated. Cleaning action is improved by injecting chemical sprays into the final drying chamber which solidify certain vapors in the exhaust stream. In the primary burning chamber the formation of large clinkers between the sides of the stoker and the refractory walls is avoided by providing a relatively wide, deep ledge of refractory material adjacent the moving edges of the stoker. In another embodiment a series of hollow perforated cylinders, arranged in a gradually sloping or vertically stepped array, may also be used as a stoker grate in the primary burning chamber to transport the material being burned through this chamber. The exhaust hot gases may be mixed with oxygen and supplied to the interior of these cylinders to prevent clogging and to assist in combustion of the material on the primary chamber.
