6″ Vertical Boiler.Spearhead Superheater
Some more progress on the 6″ vertical boiler. Not much to show, but here it is.
Actually, I have been wondering whether to continue with this blog as a “what I have done today” type diary, or whether to post less often, but when a significant milestone has been passed. Your feedback would be welcome on this decision.
The superheater is a copper item, which steam passes through, and is located in or just above the furnace. As a result the steam becomes hotter and drier and more energetic before it is passed through the engine or whatever it is being used for.
The sperheads are bronze brazed to copper pipes, but the difficult bit was bending the 1/4″ copper pipe to fit.
The tricky bit is the 2 x 90º bends, really close to each other. Does anyone have any good method for doing this? I ended up with this result, but it is not pretty, and I am sure there must be a better method for creating the bends.
The silver soldered joins are yet to be done into the brass fittings shown. I ran out of time in the workshop.
This is getting exciting! I am not too far off firing up this boiler!
Then a visit to the boiler inspector.
