PROBLEM TO BE SOLVED: To provide a denitrification equipment capable of efficiently denitrificating even an exhaust gas of a combustion equipment, which is usually difficult to be denitrificated. SOLUTION: In the exhaust gas denitrification equipment provided with a denitrification part 6, formed by arranging a nitrogen oxide denitrification catalyst for occluding X nitrogen oxides in an oxidizing atmosphere and reducing the nitrogen oxides in a reducing atmosphere in an exhaust gas passage 5 of the combustion equipment freely in contact with the exhaust gas, a reducing gas introducing part 10a is provided on the upstream side from the denitrification part 6 of the exhaust gas passage 5 and a gas supply device 10 for intermittently supplying the reducing gas is provided at the reducing gas introducing part 10a. |
