A combustion demonstration using six coal-derived liquid (CDL) fuels was conducted on a utility boiler located at the Plant Sweatt Electric Generating Station of Mississippi Power Company in Meridian, Mississippi. The test program was conducted in two phases. The first phase included the combustion tests of the two conventional fuels (natural gas and No. 6 fuel oil) and three coal-derived liquid fuels (Solvent Refined Coal-II full range distillate, H-Coal heavy distillate and H-Coal blended distillate). The second phase involved the evaluation of three additional CDL fuels (H-Coal light distillate, Exxon Donor Solvent full range distillate and Solvent Refined Coal-II middle distillate). The test boiler was a front wall-fired Babcock and Wilcox unit with a rated steam flow of 425,000 lb/h and a generating capacity of 40 MW. Boiler performance and emissions were evaluated with baseline and CDL fuels at 15, 25, 40 MW loads and at various excess air levels. Low NO/sub x/ (staged) combustion techniques were also implemented. Boiler performance monitoring included measurements for fuel steam and flue gas flow, pressure, temperature, and heat absorption, resulting in a calculated combustion efficiency, boiler efficiency, and heat rate. Emissions measurements included oxygen, carbon dioxide, carbon monoxide, oxides of nitrogen, sulfur dioxide, sulfur trioxide, acid dewpoint, particulate mass, size distribution and morphology, chlorides, and opacity. The test program demonstrated the general suitability of CDL fuels for use in existing oil-fired utility boilers. No significant boiler tube surface modifications will be required. The CDL fuels could be handled similarly to No. 2 oil with appropriate safety procedures and materials compatibility considerations. Volume 2 of a five-volume report contains the detailed boiler test results. 96 figs., 26 tabs.
