Summary:To provide a denitrification apparatus where ammonia flowing out downstream is suppressed.SOLUTION: A denitration control device is the control device of a denitrification apparatus having a denitration reactor to remove nitrogen oxides from an exhaust gas exhausted from a combustion device where ammonia is a fuel. The denitration control device has a charge amount calculation part to calculate the charge amount of a reducer based on the excessive amount of the reducer considering unburned ammonia.SELECTED DRAWING: Figure 3 【課題】脱硝装置の下流に流出するアンモニアを抑制する。【解決手段】本開示の少なくとも一実施形態に係る脱硝制御装置は、アンモニアを燃料とする燃焼装置から排出される排ガスから窒素酸化物を除去するため脱硝反応器を備える脱硝装置の制御装置である。本開示の少なくとも一実施形態に係る脱硝制御装置は、未燃アンモニアを考慮した還元剤の過剰量に基づいて、還元剤の投入量を算出する投入量算出部、を備える。【選択図】図３
