Description:
The report gives details of a Solvent Refined Coal (SRC) combustion test at Georgia Power Company's Plant Mitchell, March, May, and June 1977. Flue gas samples were collected for modified EPA Level 1 analysis; analytical results are reported. Air emissions from the combustion of coal and SRC are compared for various organic and inorganic constituents, and SO2 and NOx. The impact of the air emissions from the combustion of SRC is assessed by comparison with EPA's Multimedia Environmental Goals and existing New Source Performance Standards. Air quality emissions test data indicated that SRC SO2 and NOx emissions were 1.06 and 0.43 lb/million Btu, respectively; or about 12 and 39% under the existing NSPS of 1.2 lb/million Btu for SOx and 0.7 lb/million Btu for NOx. If the SO2 standard is reduced, SRC derived from high sulfur coal may not meet the new standard. The low NOx emissions may be a result of the abnormally high excess air that was used during the test: additional testing at normal conditions is required. Particulate emissions can probably be controlled well below the EPA standard of 0.1 lb/million Btu by installing a modern ESP, with a particulate collection efficiency of about 95%.
