Description:
The report gives results of a test to evaluate the SO2 removal performance of the lime-spray-dryer/fabric-filter system treating flue gas from the stoker-coal-fired boiler at Celanese's Amcelle plant in Cumberland, MD, in August/September 1980. Continuous monitors were used to collect data according to EPA procedures for compliance testing. Data were collected for 23 days with the boiler operating at about half load. In addition to evaluating SO2 removal by dry flue gas desulfurization, operating experience with the boiler and spray-dryer/baghouse system was obtained for 5 months, ending September 30, 1980. Data were reduced to express SO2 removal on a mass per unit energy input basis as prescribed by EPA. Test results showed the mean SO2 removal efficiency to be 70% (standard deviation of + or - 9%) when the sulfur content of the bituminous coal averaged 2%. This efficiency generally was 60-80%, except during system upsets. During the last week of testing, daily SO2 removal averaged about 80%. System availability was 73% over the 25 days of testing and 96% over the last week. Report appendices provide data and computer averages for SO2 removal and the computer program used for data reduction.
