<p>An apparatus for effectively removing nitrogen oxides contained in an exhaust gas and a removing method thereof are provided. The apparatus for removing nitrogen oxides comprises a reducing agent feeder and a catalyst reducing unit, wherein the reducing agent feeder produces a reducing agent from initial materials through a thermal reaction utilizing heat energy of exhaust gas of a first engine; and the catalyst reducing unit removes the nitrogen oxide in the exhaust gas by a catalyst reducing reaction generated by the reducing agent, and the exhaust gas of a second engine is directly provided to the catalyst reducing unit without the reducing agent feeder.</p> |
