Filter house having catalytic filter bags for simultaneously removing NOx and particulate matter from a gas stream

摘要

A filter house (12) employing a selective catalytic reduction process for removing NOx emissions from a flue gas stream while simultaneously filtering out and collecting entrained particulate matter from the stream. Accordingly, the filter house (12) includes flue gas inlet and outlet passages (18, 30) and a plurality of porous filter bags. The bags are treated with a suitable catalyst to facilitate the selective catalytic reduction process.
