<p>An incinerator system includes a main chamber (32), double reburn tunnels (41, 42), an excitor (134) within a reburn tunnel, a grate (234) near the incinerator's inlet (231) to permit the drying and initial combustion of refuse, and an ash scoop (278). The grate (234) placed at the main combustion chamber's entrance and above the incinerator's floor (33) 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 away from 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 (355) placed on the grate to both cool the grate and support combustion. <IMAGE></p> |
