The ultimate objective of this program is the commercial demonstration of an efficient, environmentally acceptable coal firing process suitable for implementation on melting furnaces throughout the aluminum industry. To achieve this goal, the program has been divided into two phases. During Phase I, detailed research and development will be performed to perfect a staged, slagging, cyclone burner for direct coal firing of a 40,000 lb open hearth aluminum melting furnace. Additives will be incorporated to remove sulfur and ash during the combustion process, thus precluding the need for downstream cleanup equipment. Also, two separate heat recuperation techniques will be evaluated. This work will be performed at Alcoa's ingot plant in Arnold, Pennsylvania (a production facility until the late 1950's), which is now a full-scale laboratory dedicated to investigations of alternate fuels, melting, ingot casting, and metal treatment. Phase II implementation is currently planned for Alcoa's Lafayette, IN, Works, where two of the ingot plant's five open hearth melting furnaces will be converted to utilize coal. In addition to confirmation of data gathered in Phase I, the effect of extended production schedule operation on equipment and efficiencies will be determined.
