<p>A reducing method of a nitrous oxide and a nitric oxide included in an exhaust gas is provided to reduce at the same time a nitric oxide and a nitrous oxide in an exhaust gas and to use advantages of a thermal plasma. A reducing method of a nitrous oxide and a nitric oxide included in an exhaust gas comprises steps of: supplying a nitrogen having a purity 99.9% or more; ejecting a nitrogen radical by a hypersonic flame by producing the nitrogen radical from a thermal plasma unit; and reducing at the same time the nitric oxide and the nitrous oxide in an exhaust gas by mixing the nitrogen radical.</p> |
