Abstract
A combined flow mixing, tempering and noise suppressing apparatus for a selective catalytic reduction system, and method of use thereof is provided. The suppressing apparatus is positioned downstream of a gas input duct of the selective catalytic reduction system in order to provide improved flow uniformity and reduced noise at the entrance to the SCR system with minimal pressure loss. The combined flow mixing, tempering and noise suppressing apparatus includes lobe depressions that extend toward a centerline axis of a gas input duct of the selective catalytic reduction system and alternating lobe protrusions leading away from the centerline axis. The combined flow mixing, tempering and noise suppressing apparatus can include a means for introducing a secondary stream, such as an air manifold or an air bustle in fluid communication with the selective catalytic reduction system.
