<p>PURPOSE:To provide a discharge denitration device capable of obtaining high denitration performance without being influenced by load change of an engine for a device to remove nitrogen oxides contained in discharge gas of an internal combustion engine under a corona discharge denitration method. CONSTITUTION:Gas discharged in accordance with load of an engine is detected by a gas flow detector 12 and a NOx density detector 13. This output signal is judged by an evaluation device 11 and a control signal is delivered to a control device 10, and discharge power charged to an discharge electrode 8 provided on a discharge pipe 7 of the engine is controlled.</p> |
