ABSTRACT:
An apparatus is provided for injecting fuel in the form of pieces of various sizes into a burning zone of a kiln having an end inlet. The apparatus includes two rubber tires rotating in opposite directions, at least one motor for rotating the tires, an entrance chute, and an exit chute. The tires rotate about horizontal and parallel axes that are in an inclined plane and spaced such that the outer radial surfaces of the tires are generally adjacent. The entrance chute has a vertical inlet portion for receiving the fuel pieces and downwardly accelerating the fuel pieces by gravity and an outlet portion open adjacent the tires for feeding the fuel pieces between the tires. The tires elastically deform around the various size fuel pieces and project them as the tires rotate. The exit chute has an axis perpendicular to the inclined plane of the tire axes for directing the projected fuel pieces through the kiln end inlet. The apparatus also includes mechanisms for making adjustments to: the inclination of projection; the windage of projection; and the spacing between the tires.
