Alternative Control Techniques Document--NOx Emissions From Utility Boilers.
This document supports compliance by states with the NAAQS for ozone. It provides technical information on NOx controls for fossil fuel-fired utility boilers that state and local agencies may use to develop and implement regulatory programs to control NOx emissions from fossil fuel-fired utility boilers. It was prepared by EPA under Section 183(c) of new Subpart 2 to Part D, which was added to the CAA by the CAAA of 1990.
This alternative control techniques document describes available techniques for reducing NOx emissions from utility boilers. Discussion of the formation of NOx and uncontrolled emission levels are included. Control techniques include overfire air, low NOx burners, flue gas recirculation, reburn, selective noncatalytic reduction and selective catalytic reduction.
