DEVICE FOR REMOVING NITROGEN OXIDE AND METHOD FOR REMOVING NITROGEN OXIDE

摘要

PROBLEM TO BE SOLVED: To provide a device for removing a nitrogen oxide that effectively removes a nitrogen oxide included in an exhaust gas, and to provide a method for removing the nitrogen oxide.SOLUTION: A device for removing a nitrogen oxide includes a reducing agent supplier that generates a reducing agent from an initial material by thermal reaction using the thermal energy of an exhaust gas of a first engine and a catalyst reducing section that removes the nitrogen oxide included in the exhaust gas of a second engine by catalytic reduction reaction using the reducing agent. The exhaust gas of the second engine is supplied to the catalyst reducing section without passing through the reducing agent supplier.
