Stewart, Jr, D L

Progress is reported on the demonstration of an efficient, environmentally acceptable coal firing process suitable for implementation on melting furnaces throughout the aluminum industry. During the report period, startup operations and system checkout were completed for the two-stage Alcoa/DOE slagging coal combustor. Process flow diagrams and an equipment layout (Figures 12.1-12.4) and a process description for the pilot facility are presented. The unit is designed to burn 300 lb/h coal with an additive for sulfur removal such that downstream cleanup of the products of combustion is not required. Following completion of startup and debugging operations, combustion tests with coal were begun. However, a coal dust explosion and fire which occurred on February 3, 1981 in the coal handling area halted work for an estimated 4 to 6 months. The indicated activities are described in detail.
