The Steamboating Forum

Hi Bart & Steamboating Friends

Yes, I gather condensation is a serious problem. I have been told by a mono-tube boilered SBA Member that he has now given up on his water separator as it was tending to cause condensation of the steam and act rather like a condenser. One wonders if the Hereschoff system had that problem. Anyway the same correspondence reported that there is a thermocouple at the start of the 'superheater' coils and at the end so that an eye can be kept on whether the temperature is getting too high. Apparently too much superheat and the boiler becomes unstable.

I am grateful for all the extra information that everybody has been feeding me as it is all interesting but rather shows that what I thought was a thorough literature search is far from it. The dilemma is how much more to chase up and read to incorporate in the article. Will it add anything important or merely corroborate what has been discovered?

Going back to Fred's questions about the boiler, I don't have more answers yet but here is the CAD picture to date:

The Herreshoff system was used on fairly good size power plants; this meant that condensation losses were significantly less. Example 6x10.5x10, with boiler tubing at 2" diameter.
