Re: Exhaust Outlet Valve

Simon,

Certainly in most marine power plants on ships it would be common practice to use the waste heat from the exhaust to heat water up for several reasons, I have never seen a cooling system for an exhaust (mind you I have never sailed on a sub either). I would suggest that its a protective sleeve around the main exhaust pipe. If the hot exhaust pipe was in direct contact with, or partially submerged/splashed by seawater the metal corrosion would be greatly accelerated. I see it with steam pipes on deck, unlagged and hot they don'y be long turning into a rust mush once they get in contact with seawater.

Regards,

Mark
