Abstract
PURPOSE: To discharge the exhaust gas while suppressing the concentration of NOx in the exhaust gas below the prescribed value, by supplying NH3 effectively and variably with the passage of time in opposition to the total introduced quantity of the exhaust gas and the irregular fluctuation of the concentration of NOx in the exhaust gas relating to the time, in the dry denitration plant for flue gas using NH3 as the reducing agent.
