<P>PROBLEM TO BE SOLVED: To provide an ammonia blow-in quantity control method in a denitration catalyst device capable of stably controlling the concentration of NOX in a flue and capable of reducing the amount of leaked ammonia in the exhaust gas treatment equipment of a waste treatment furnace. <P>SOLUTION: In the ammonia blow-in quantity control method for the denitration catalyst device for decomposing NOX by blowing ammonia in the denitration catalyst device in the exhaust gas treatment equipment for treating the exhaust gas discharged from the waste treatment furnace of the waste treatment equipment, the concentration of NOX at the inlet of the denitration catalyst device is proportional to the amount of the exhaust gas passing through the denitration catalyst device. Therefore, ammonia is blown in the denitration catalyst device in an amount necessary for decomposing NOX calculated on the basis of the amount of the exhaust gas to decompose NOX to control the concentration of NOX at the outlet of a flue. <P>COPYRIGHT: (C)2003,JPO |
