Abstract
A method and apparatus are described for environmentally sound usage of combustible solid waste in operating rotary cement kilns. A cement kiln is modified to contain a port in the rotary cylinder for delivery of combustible solid waste into the kiln for burning in contact with calcining mineral material. The port is provided with a closure and means for moving the closure between a port-opened and port-closed position at predetermined times during rotation of the kiln cylinder. The invention allows efficient use of solid waste as supplemental fuel in the cement manufacturing process.
