Abstract
A feed chute apparatus for injecting fuel into a rotating cement kiln by gravity. The apparatus, which is positioned adjacent to a cement kiln and supported at an angle of inclination sufficient to allow tires or other combustible materials to be gravity fed into the cement kiln, has a feed ramp for guiding the combustible material into the kiln. A gate having a pair of opposing posts is positioned at the end of the feed ramp to control the rate of feed of the combustible material. In the rest position, the posts are extended in relation to the feed ramp to prevent the flow of combustible material. When the kiln rotates to a position where the feed opening in the wall of the kiln is aligned with the feed ramp, the gate retracts to allow the combustible material to be gravity fed into the kiln. The angle of inclination is selected so that there is sufficient gravitational force on the combustible material to slide down the feed ramp and into the kiln, but not so steep that the combustible material binds up in the feed chute.
