Description of the source (including control equipment). Please see the attachments for source or process flow diagram: The Logan Generating plant uses bituminous pulverzized coal. The coal is burned in low nox burners utilizing overfire air. A selective catalytic reducer uses ammonia to reduce Nox. The flue gas then passes through an air preheater, spray dry absorber to reduce Sox, and fabric baghouse. Industry/SCC/NAIS 221112
