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 throughput 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.
