ABSTRACT:
Sluice gate members mounted for swinging movement about a shaft offset from the center of a furnace and arranged to be moved both gradually and discontinuously are interposed between an upper pyrolysis and precombustion chamber and a lower afterburning chamber. The movement of these sluice gate members causes particles of the fire bed supported on them to drop down into the afterburning chamber, largely in the form of embers, at about the same rate as additional waste material is added to the fire bed, so as to maintain a fire bed of approximately constant size. The sluice gate members are hollow and secondary air is blown into them near the shafts on which they are mounted and flows out through holes on their bottom surfaces and in their facing tip edges and then proceeds downward to contribute to the afterburning process.
