Stewart, Jr, D L

Shakedown operations on a 300 lb/h staged slagging cyclone coal combustor have continued during the 14th quarter of the contracted research and development program. The ultimate objective of the program is the development of an efficient, environmentally acceptable coal firing process suitable for implementation on melting furnaces throughout the aluminum industry. Four extended coal combustion tests with lithium carbonate additive were conducted during the report period, but all were terminated before attainment of steady-state conditions because of mechanical system problems. Work to solve the problems and begin the experimental program will continue in the next quarter. Discussions were held with three outside firms concerning the advisability of retaining the services of one or more as technical consultants for the project. It was determined that retention of a technical consultant would not be desirable at this time because of the unique nature of the existing experimental unit.
