PROBLEM TO BE SOLVED: To provide a highly economical catalyst restrengthening treatment method in a denitration apparatus. SOLUTION: A part 12 to be strengthened of a catalyst 9 is strengthened again by impregnating it with a strengthening agent liquid; thus, not only the part 12 to be strengthened but also the catalyst 9 can be prevented from being degraded and abraded. Since a required denitration performance can be obtained by a catalyst 9 already set up though an operation to impregnate the part 12 to be strengthened with a strengthening agent liquid is necessary, this method is highly economical in comparison with the case when a degraded and abraded catalyst 9 is required to be replaced by a new catalyst 9. |
