Abstract

PURPOSE: To recycle exhaust gas, eliminating an increase in NOx levels due to decomposition of unreacted reducing agents by use of an apparatus wherein exhaust gas is sucked from the rear current of a catalytic reaction device provided in an exhaust gas-flowing passage, and is recycled to a fire furnace in a steam-generating apparatus.
