The demonstration of an advanced cyclone coal combustor, with internal sulfur, nitrogen, and ash control, for the conversion of a 23 MMBtu/hour boiler to coal: Second quarterly progress report, June 1, 1987-August 31, 1987

As part of the Department of Energy's Clean Coal Program, Coal Tech Corp. is demonstrating the commercial readiness of an advanced cyclone coal combustor for ''new'' or ''retrofit'' applications on industrial or utility boilers. This advanced combustor can control SO/sub 2/ and NO/sub x/ emissions to near new source performance standards and at the same time retain and reject ash, sorbent, and sulfur compound solids as slag upstream of the boiler. During this period, all the major components required for the modification of the combustor facility to dry coal operation were ordered and delivered to the test site. The primary facility modifications consisted of the addition of a coal storage, delivery and feed system, and a stack particulate scrubber system. Sub-contracts for installing this equipment were awarded to three contractors. The installation work was scheduled for the September and October 1987 time period. Additional accomplishments during this period were: the stack scrubber design was modified for placement on the roof of the boilerhouse, instead of inside the building as in the original design; a limited development effort was implemented to determine the appropriate design of a pneumatic dry pulverized coal and limestone conveying system; and a control system for the scrubber was designed.
