PROBLEM TO BE SOLVED: To reduce an amount of mist that enters a compressor of an exhaust turbine turbocharger by improving efficiency of collecting a mist separator.SOLUTION: In an exhaust gas recirculation system 21, part of an exhaust gas discharged from a marine internal combustion engine 2 is sent back to the suction port side of a compressor 7 and burned with combustion air, wherein the compressor 7 is installed upstream of the marine internal combustion engine 2 via recirculation piping 22 and supplies the combustion air to the marine internal combustion engine 2. An EGR valve 23, a scrubber 24, steam supply unit 25 and a first mist separator 26 are connected to the recirculation piping 22 in the order from the upstream side to the downstream side. In the steam supply unit 25, steam introduced via a steam supply pipe 27 blows into the exhaust gas introduced from the scrubber 24 via the recirculation piping 22. |
