Description:
The report gives results of a comprehensive emission sampling and analysis of a pilot-scale, atmospheric-pressure, coal-fired, fluidized-bed combustor (AFBC). Screening data on organic and inorganic pollutants and indications of biological activity were obtained. The Babcock and Wilcox/Electric Power Research Institute AFBC at Alliance, OH. (B and W/EPRI/Alliance), with a coal-firing capacity of 880 kg/hr was tested. Air pollutant emissions of trace elements were measured upstream of particulate controls. Assuming a control efficiency of 99.9%, necessary to meet the utility boiler Federal NSPS for particulate of 13 ng/J, emissions of trace elements are not significant. Elemental concentrations do not appear to be significantly different from other FBCs or conventional coal combustion systems. Limited further analyses for specific polynuclear aromatic compounds indicate that emissions of these compounds are probably of no concern. Analysis of laboratory-generated leachates from solid waste samples reveals that trace metal concentrations are well below Federal hazardous waste criteria. Positive test results for mutagenicity and cytotoxicity screening tests require further investigation.
