More Information
Summary:An exhaust gas denitrizer removes nitrogen oxides from rejoined exhaust gas using a denitrification reactor after supplying ammonia gas to the rejoined exhaust gas made up of main exhaust gas cooled by a fuel economizer by flowing through a main duct and bypass exhaust gas maintained at high temperature by flowing through a bypass duct adapted to bypass the fuel economizer. At a meeting place between the main exhaust gas and bypass exhaust gas in the main duct, three partition plates are installed with plate surfaces turned to an inflow direction of the bypass exhaust gas, partitioning a main exhaust gas channel into a plurality of subchannels. Upstream-side ends of the partition plates face the incoming bypass exhaust gas by being shifted from one another toward an upstream side of the main exhaust gas starting from an inflow side of the bypass exhaust gas.
