Abstract
A combustion system for ships operated at low cost is provided. A combustion systemfor ships includes an internal combustion enginethat burns fuel, an exhaust line Lthrough which exhaust gas flows, the exhaust gas being generated through combustion of the fuel in the internal combustion engine, an exhaust heat recovery devicethat is disposed in the exhaust line Land that recovers exhaust heat from the exhaust gas discharged from the internal combustion engine, and a denitration devicethat is disposed in the exhaust line Land that removes nitrogen oxide from the exhaust gas using a denitration catalyst. The denitration deviceis disposed downstream from the exhaust heat recovery devicein the exhaust line L. The denitration catalyst contains 43 wt % or more of vanadium pentoxide and has a BET specific surface area of 30 m/g or more.
