| Abstract |
The report gives results of tests investigating the use of Western coal fly ash for scrubbing SO2 from powerplant flue gas, on a 130-scfm pilot scrubber at the Grand Forks (ND) Energy Research Center and on a 5000-acfm pilot scrubber at the Milton R. Young Generating Station (Center, ND). Tests of the 130-scfm unit were designed to investigate the effects of increased sodium concentration on SO2 removal and rate of scaling. Parameters investigated included liquid-to-gas ratios (L/G), stoichiometric ratios (CaO/SO2), and sodium concentration. Results indicate increased SO2 removal and decreased rate of scaling as sodium concentration increases. Tests of the 5000-acfm unit generated design and operating data for a full-scale 450 MW fly ash alkali scrubber to be constructed at the same Station. Results indicate that sufficient SO2 can be removed to meet NSPS requirements, using only fly ash alkali when burning 0.75% sulfur lignite. |
