The demonstration of an advanced cyclone coal combustor, with internal sulfur, nitrogen, and ash control for the conversion of a 23 MMBTU/hour oil fired boiler to pulverized coal: Fourth quarterly project progress report, January 1, to March 31, 1988
An advanced cyclone coal combustor for ''new'' or ''retrofit'' applications on industrial or utility boilers is being demonstrated. This advanced combustor demonstrates control of SO/sub 2/ and NO/sub x/ emissions to near new source performance standards and at the same time retains and rejects ash, sorbent, and sulfur compound solids as slag upstream of the boiler. During this period the Phase III effort was continued. Five separate tests were conducted covering almost 50 parametric condition variations. A total of 100 hours of combustor operation were completed. The main technical goals were to: improve coal combustion efficiency above the 80% level obtained earlier; achieve coal ash slagging within the combustor; and obtain good, blockage-free, rejection of slag through the combustor slag tap. Other project goals of staged combustion for NO/sub x/ control, as well as sulfur capture via limestone injection were implemented. All of these technical goals were substantially achieved during this reporting period.
