Cement advanced furnace component and system optimization. Volume 1. Final report, August 1989-April 1993

Research and development of the Cement Advanced Furnace (CAF) vertical shaft kiln has been performed under the sponsorship of the Gas Research Institute and Southern California Gas Co. by Textron Defense Systems and Fuller Co. The CAF represents a low cost, energy efficient, very low polluting alternative to traditional rotary kilns for the production of Portland and specialty cements. The testing program has resulted in the development of an integrated shaft furnace that has produced clinker in a pilot plant at rates up to 2200 lb/hr. The unit can be scaled to commercial sizes with the aid of a mathematical model of the equipment and process developed as part of this effort. Cement produced in this program is as strong as, but easier to grind than, cement produced in conventional rotary kilns. Polluting emissions from the CAF are lower than from conventional cement processing equipment by virtue of the use of natural gas as fuel and a low combustion temperature.
