Description:
The report describes and assesses the potential impact of air emissions, wastewater effluents, and solid wastes from the operation of dry bottom industrial boilers firing pulverized bituminous coal. Air emissions were characterized by a literature survey and field sampling. Significant emissions resulting from coal combustion were particulate matter, sulfur oxides (SOx), nitrogen oxides (NOx), hydrocarbons, polycyclic organic materials (POM), and a number of elements. The potential environmental impact of each emission species after passing through state-of-the-art controls was individually assessed using a calculated quantity known as the source severity. Species determined to have source severities greater than 1.0 were NOx (1.7), SOx (2.2), and POM (6.0). Pollutant concentrations were also measured in wastewater and solid waste streams. Effluent source severities were found to be significantly less than 1.0 for most species. The potential impact of solid waste discharges on the quality of air and of ground and surface water was also found to be minor when available controls were applied.
