PROBLEM TO BE SOLVED: To prevent the clogging of a urea water injection nozzle or an exhaust pipe. SOLUTION: This marine exhaust gas denitration device 1 includes a reactor 2 for producing ammonia from urea water, the urea water injection nozzle 32 for supplying the urea water into the reactor 2, and a SCR catalyst part 4 provided in an exhaust gas passage on the downstream side of an exhaust turbocharger 5 to be driven by exhaust gas from a diesel engine 3 for performing exhaust gas denitration using the ammonia supplied from the reactor 2. To the reactor 2, the exhaust gas is guided which is extracted part of the exhaust gas to be supplied from the diesel engine 3 to the exhaust turbocharger 5. COPYRIGHT: (C)2011,JPO&INPIT |
