Abstract:
A combustion system for ships operated at low cost is provided. A combustion system  1  for ships includes an internal combustion engine  20  that burns fuel, an exhaust line L 2  through which exhaust gas flows, the exhaust gas being generated through combustion of the fuel in the internal combustion engine  20 , an exhaust heat recovery device  40  that is disposed in the exhaust line L 2  and that recovers exhaust heat from the exhaust gas discharged from the internal combustion engine  20 , and a denitration device  50  that is disposed in the exhaust line L 2  and that removes nitrogen oxide from the exhaust gas using a denitration catalyst. The denitration device  50  is disposed downstream from the exhaust heat recovery device  40  in the exhaust line L 2 . The denitration catalyst contains 43 wt % or more of vanadium pentoxide and has a BET specific surface area of 30 m 2 /g or more.

Claim (Index 3):
The combustion system for ships according to  claim 2 , wherein the electric power generated in the exhaust heat recovery device is used to supplement motive power generated by the internal combustion engine.
