That diagram is about right. In large plant practice as shown, engineers would adjust the pump speed as necessary. That would negate the need for a feed water bypass/return as seen on plumbing of smaller vessels with pumps driven directly by the main engine.

If I'm not mistaken, the '102' indicates the square feet of heating surface. If that is the case, then the weight figure is realistic, and it would be heaps larger than is needed for either of your examples.

That little engine would get away with a boiler of a modest 20-30sqft of heating surface ...

Now that will be quite nice Mike!

Another ...

Welcome to the forum Steve. It sounds like you have a lot of exciting ideas to sus out!
