Pulverized-Coal Firing of Aluminum-Melting Furnaces. Quarterly Technical Progress Report, July-September 1982

摘要

Shakedown operations on a 300-pound-per-hour staged slagging cyclone coal combustor continued during the fifth year of the contracted research and development program. The objective of the program is the development of an efficient, environmentally acceptabe coal-firing process suitable for implementation on melting furnaces throughout the aluminum industry. One pilot coal-combustion test was conducted in a continuing effort to complete mechanical shakedown. The test was significant in that a twenty-seven-hour period of coal-combustion time was obtained; the longest period in previous tests was eight hours. Following the test, a number of process modifications were made. A renewed bench-scale program to develop improved desulfurizing slags was begun. (ERA citation 08:026581)
