You can operate a scotch marine propulsion boiler on SW as a get 'er home last resort.
We contaminated our feed water with SW in some accident that I can't remember, and had severely contaminated boilers by the time we got in. You have to manage the boiler carefully with continuous bottom blowdown while steaming it.
It is a real PITA to get the boiler water back down to about 100 PPM when you get clean feed water.
All these steam questions, I regard as Scotch Marine boiler questions and answer as such.
