Abstract The combustion studies reported in this paper are a result of testing performed with several different burner modifications in a 650 MW wall-fired pulverized coal boiler. Two of Cleveland Electric Illuminating Company's 650 MW Babcock & Wilcox supercritical once-through boilers were retrofitted with new burners and tested extensively. Also, testing and video taping of flame patterns of initial prototype designs was done in a 50 MW wall-fired boiler. The conclusions drawn from this testing, although somewhat subjective, should be of interest to anyone attempting to improve combustion in a similar boiler. The testing program began in early 1986 following installation of new burner air registers in CEI's Avon 9 boiler and conversion of the furnace from pressurized to balanced draft operation. Following these changes, the unit suffered severe combustion problems which prompted an extensive testing program as attempts were made to identify possible causes and fixes. Since then, additional testing has transpired as new problems have arisen and new burner innovations were developed and tested. The most recent work has encompassed testing on Eastlake 5, an identical sister unit to Avon 9, before and after retrofitting with the new burner. Data from the various tests on all three boilers has been used to assess the impact of burner design features on furnace temperatures, slagging patterns, CO levels in the combustion zone and flame patterns.
