Abstract

PURPOSE:To completely remove NOX, by controlling the supplied quantity of ammonia depending on the measured quantity, NOX concentration and temperature of exhaust gas, and supplying the ammonia to the downstream of a position when the measurement of NOX is achieved. place. CONSTITUTION:Signals obtained by an NOX concentration measuring unit 2 and an exhaust gas quantity measuring unit 3 are integrated to calculate the total quantity of NoX contained in exhaust gas to produce the first ammonia control signal 4. The ratio of the quantity of ammonia to that of NOX is determined by a ratio setting unit 5 from the first ammonia control signal 4 and a signal corresponding to the temperature in a denitration reactor 1 to supply a signal to a flow controller 6. A signal is applied from the controller 6 to a flow meter 9 and a control valve 10 to regulate the degree of opening of the control valve to supply a prescribed quantity of ammonia from an ammonia feeder 8 to injection nozzles 13 provided in the exhaust outlet duct 12 of an internal combustion engine 7.
