Steam Generators, I used to know, but all I remember now is that I signed a sheet of paper that said i know nothing!
As far as steam generators go, you might want to recognize that the tubes are submerged at all times, if not bad things happen. Being submerged they are only subjected to the highest temp of the "fluid" on either side. For a 600# steam plant, that might be somewhere in the neighborhood of 500 F. Plants and specs vary though. Thats about all I should say.
