Denitration catalyst management method and apparatus for managing a denitration catalyst
2003
Periodic maintenance management (step S110) and daily management based on data obtained by (step S 120), manages the aging data for each unit of denitration catalyst (101), management and next periodical inspection of aging the performance transition prediction (step S130) of up to at the time. Then, it is determined whether the deterioration of the denitration catalyst (101) has reached a level that can not maintain performance of the exhaust-gas denitration apparatus (100) (step S 140), as a result, if the deterioration is authorized (Step S 140: deterioration) performs reproduction, exchange, and additional denitration catalyst (101) (step S150,160,170), performs a modified if necessary (step S180), if it is certified as available (step S140: enabled) the replacement of the denitration catalyst (101), does not perform the playback (step S190).
