Title:
排ガス脱硝装置、焼却炉および排ガス脱硝方法
Document Type and Number:
Japanese Patent JP6616737
Kind Code:
B2
Abstract:
A flue gas denitration system (4) includes a catalytic reactor (43) accommodating a plurality of catalytic modules (439), into which a flue gas flows, and a flue gas heater (41) provided on an upstream side of the catalytic reactor (43) in a flow direction of the flue gas. In the flue gas denitration system (4), switched are a first denitration state in which the flue gas is denitrated by using the plurality of catalytic modules (439) in the catalytic reactor (43) and a second denitration state in which the flue gas is denitrated by using a catalytic module(s) (439) less than those used in the first denitration state while a temperature of the flue gas flowing into the catalytic reactor (43) is made higher than that in the first denitration state by using the flue gas heater (41). Thus, by making the temperature of the flue gas flowing into the catalytic reactor (43) higher, it is possible to suppress deterioration in denitration performance in the case of using part of the plurality of catalytic modules (439) for denitration.
