<p>An air-starved, batch burn, modular, municipal waste incinerator is designed to oxidize unsorted loads of heterogeneous materials in quantities ranging from 5 to 500 tons per 12 to 15 hours. The system is designed such that through air mixing, air turbulence, and temperature control, it is possible to burn this material with a highly favorable stack emission product, without the need for bag houses, dry scrubbing, or other elaborate down stream air processing equipment. The incinerator includes a primary combustion chamber (12) connected to a secondary combustion unit (14) by a gas transfer tube (16,50). Solid material in the primary (12) is oxidized - or gasified - without live flame. Flammable gas is vented into the secondary (14) for ignition. Combustion gases from the primary chamber are completely burned in the secondary combustion unit (14) as the gases pass upwardly through an air mixing ring (66) and tangentially disposed re-ignition burners (70). The tangential orientation of the re-ignition burners (70) creates a vortex through which the combustion gases travel before exiting from the stack.</p> |
