MARINE DENITRATION SYSTEM, MARINE VESSEL EQUIPPED WITH SAME, AND CONTROL METHOD FOR MARINE DENITRATION SYSTEM

摘要

Provided is a marine denitration system capable of supplying in an energy-saving manner the power supplied to an ammonia generation device that generates ammonia used for denitration. This system is equipped with: an ammonia generation device (2) supplied with power from an onboard power system (30); an SCR catalytic unit (4) that performs exhaust gas denitration; a hybrid exhaust turbine supercharger that generates electricity using exhaust gas energy from the main engine (3) and supplies power to the onboard power system (30); a shaft generator motor (13) that is capable of a power-generating operation which supplies power to the onboard power system (30), and that is driven by power supplied from the onboard power system (30) to support a propeller shaft (10); and a power management system (72) that controls the supply of power to the ammonia generation device (2), the power output from the hybrid exhaust turbine supercharger, and the supply of power to and the power output from the shaft generator motor (13).
