Rubbish and refuse incinerator

摘要

An incinerator and method for burning both sorted and unsorted rubbish and refuse cleanly and efficiently. Rubbish is inserted in a non-clogging hopper where it is preheated and preliminarily combusted as it moves downwardly to a primary combustion chamber where air is added. A moving grate beneath the primary combustion chamber draws ashes and uncombusted materials downwardly away from that chamber. Gases of combustion are further combusted as they are drawn by the natural draft in the incinerator through a secondary combustion chamber and gas circulating and flyash collecting chamber before exiting through an exhaust. The natural draft through the incinerator is controlled by a series of movable baffles and doors. Steam is inserted into the hopper and secondary combustion areas to enhance combustion of certain rubbish and materials while fresh air heated by the incinerator is added to the primary and secondary combustion areas and used to heat the hopper to begin slow combustion in the hopper and to aid later combustion in the said areas.
