A rotary kiln device for incinerating combustible materials such as municipal and commercial waste materials. The kiln is a co-current gas-material flow apparatus. The kiln is divided by means of a dam into a drying zone and a combustible zone. Waste material is retained within the drying zone sufficiently long so that that moisture contained in the material is driven off. Air for combustion is supplied directly to the combustion zone, bypassing the drying zone so that self-sustaining combustion may take place.

Apparatus for incinerating combustible material

A gas-solids heat/exchanger apparatus particularly designed for cooling the particulate material such as calcined limestone or cement clinker, but may also be used as a dryer and/or material heater. The apparatus includes a casing having an upper particulate material inlet and a lower particulate material outlet. Upper and lower grates extend on an angle or a slant from the inlet to the outlet for holding a bed of material. Gas is supplied to an inlet plenum chamber on one side of the lower grate for passage through the grates and the bed of material to an outlet plenum chamber. The lower grate is perforated to permit gas to pass therethrough while supporting the bed of material. The upper grate includes a plurality of spaced apart, vertically oriented, perforated slats. Various parameters or gas flow rates, pressure drops and positioning of the upper grate slats are disclosed.
