Technology assessment report for industrial boiler applications: coal cleaning and low sulfur coal. Final report, Sep 78-Jul 79

The report assesses the use of three pollution control technologies--low sulfur coals, physical coal cleaning (PCC), and chemical coal cleaning (CCC)--to comply with SO2 emission regulations. It is one of a series to be used in determining the technological basis for a new source performance standard for industrial boilers. Candidate systems were selected after consideration of 7 naturally occurring low sulfur coals, 5 levels of sulfur removal by PCC, and desulfurization by 11 CCC processes. The best systems of emission reduction were identified for three coals at each of five emission control levels. For regulatory purposes this assessment must be viewed as preliminary, pending results of a more extensive examination of impacts called for under Section III of the Clean Air Act Amendments.
