See full text

A catalyst arrangement deciding method for a flue gas denitrizer including a catalyst layer disposed in an exhaust gas passage includes: a step of investigating a location dependence of a degradation state of a catalyst in the catalyst layer after a lapse of a period of operation; and a step of deciding a first region of the catalyst layer in which a first catalyst is used and a second region of the catalyst layer in which a second catalyst different from the first catalyst is used, on the basis of the location dependence.
