DEVICE FOR CONTROLLING DENITRATION APPARATUS, DENITRATION APPARATUS PROVIDED WITH THE DEVICE, BOILER PLANT PROVIDED WITH THE DEVICE, AND METHOD FOR CONTROLLING DENITRATION APPARATUS
A control system (20) of a NOx removal device is provided with reagent introducing means (15) for introducing a reagent into a fluid, a temperature measuring device (21) that measures a temperature distribution of the fluid, a reagent-concentration calculating portion (23) that calculates a concentration distribution of the reagent introduced into the fluid with the temperature distribution determined at the temperature measuring device (21), a reagent-flow-rate determining portion (24) that determines a flow rate of the reagent that the reagent introducing means (15) introduces in accordance with the concentration distribution calculated at the reagent-concentration calculating portion (23), and a reagent-introducing-means control portion (25) that controls the reagent introducing means (15) so as to introduce the reagent into the fluid at the flow rate determined at the reagent-flow-rate determining portion (24).
