TITLE: INCINERATOR IMPROVEMENTS INVENTOR: JOHN N. BASIC, SR. ABSTRACT Improvements for an incinerator system including double reburn tunnels, an excitor within a reburn tunnel, a choker for closing off part of a reburn tunnel, a grate near the incinerator's inlet to permit the drying and initial combustion of refuse, an ash scoop which remains out of the water during most of its operation. The use of dual reburn tunnels, along with a damper that permits the closure of at least one of them, permits the efficient and environmentally acceptable utilization of the main incinerator chamber even with minimal refuse contained there. With less refuse, only one reburn unit operates; it will still have sufficient heat and throughout to maintain, with minimal auxiliary fuel, the temperatures needed for complete combustion. An excitor, or solid stationary object placed within the reburn tunnel, permits the retention and reflection of the heat generated by the burning to assure complete combustion of all hydrocarbons within the reburn unit. Additionally, the air utilized in the reburn unit may enter through the excitor for the efficient distribution and concomitant combustion. A damper closing off a portion of a reburn unit permits its efficient operation even when the main combustion chamber contains very little refuse. Additionally, it permits the incinerator to achieve operational temperatures prior to the introduction of refuse by using only a minimal amount of auxiliary fuel. A grate placed at the main combustion chamber's entrance and above the incinerator's floor permits the retention of newly introduced refuse for a brief period of time. During this time, the refuse may dry, loose its volatile hydrocarbons, and then drop through to the main chamber's floor and undergo its usual combustion. For very high Btu waste, the grate permits the initial, very hot burning to occur off of the incinerator floor to prevent slagging. A fluid may pass through the grate to keep it from overheating. In particular, air may enter the main incinerator chamber through nozzles placed on the grate to both cool the grate and support the combustion. The ash scoop has a retaining and a nonretaining configuration. It moves along a track downward into the pit while poised in its nonretaining configuration. Once in the pit, it moves to its retaining position to grab debris within the pit. It then moves back out of the pit along the track until it reverts to its nonretaining configuration to dump the ashes dragged out of the pit. - 2 -
