摘要
With the invention, electrical energy required when producing ammonia for use as a reducing agent in denitration is supplied with low energy consumption. Provided are an ammonia producing device (2) that includes a hydrogen producing unit (81) for producing hydrogen from water and a nitrogen producing unit (83) for producing nitrogen from air, and that produces ammonia from the hydrogen produced by the hydrogen producing unit (81) and the nitrogen produced by the nitrogen producing unit (83), and an SCR catalyst unit (4) that is provided in an exhaust gas passage of a main engine (3) for marine vessel propulsion and performs denitration of the exhaust gas with the ammonia produced by the ammonia producing device (2). A power management system (72) controls, based on a load of the main engine (3), electric power output of an electric power generator that generates electric power using exhaust energy from the main engine (3). At least a portion of the electric power controlled by the power management system (72) is supplied to the ammonia producing device (2).
