SHIP COMBUSTION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2018/047383

Kind Code:

A1

Abstract:

Provided is a low-operating-cost ship combustion system. A ship combustion system 1 that comprises: an internal combustion engine 20 that combusts fuel; an exhaust path L2 through which flows exhaust gas generated by combustion of fuel at the internal combustion engine 20; an exhaust heat recovery device 40 that is arranged on the exhaust path L2 and recovers exhaust heat from the exhaust gas discharged from the internal combustion engine 20; and a denitration device 50 that is arranged on the exhaust path L2 and removes nitrogen oxides from the exhaust gas by means of a denitration catalyst. The denitration device 50 is arranged on the exhaust path L2 downstream of the exhaust heat recovery device 40. The denitration catalyst contains at least 43 wt% of vanadium pentoxide and has a BET specific surface area of at least 30 m2/g.
