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 2):
The combustion system for ships according to  claim 1 ,\n wherein the exhaust heat recovery device includes a turbine device and an exhaust gas economizer, the exhaust gas economizer generates steam using, as heat sources, exhaust gas discharged from the internal combustion engine and exhaust gas supplied from the turbine device, and the turbine device generates electric power using the exhaust gas discharged from the internal combustion engine and the steam supplied from the exhaust gas economizer.
