Serious Boiler

Look at this thing!
Someone gave me this, all plastered with blanket insulation of
some kind (should have taken a picture, but didn't; I was too
concerned with taking it off). At first I thought it was made of
steel, because a magnet stuck to it, but it turned out that the
magnet was sticking to the steel mesh that was part of the
insulation. Turns out that this is an amazing silver-brazed
copper boiler, complete with water cross-tubes in the flue,
superheater, and GOK what else.
Here's how it looks just now: bare of insulation, broken sight
glass removed, all valves and fittings freed up and moving
nicely.
It looks like a very old boiler, as you can see from the wooden
valve wheels. Nonetheless, so far it looks very solid. I'll have
to make blanking plugs, etc. and give it a pressure test, but at
the very least it makes a dandy paperweight!

Perhaps it needs pickling? Followed by a pressure test. The
water tubes look awesome, should generate steam very well.

Pickling for sure.🍾 De-scaling, too.

There! Pickled. At least enough to do a pressure test; there's
still some scale in there, though.
The scabs on the outside are not pits; they're raised blobs that
I think are what's left of the old insulating material. Anyway,
I can scrape them off.
First inspection looks good. It holds water at atmospheric
pressure, and that's a great start. No leaks from valves,
either. The silver solder is smooth and uniform-looking, and I
anticipate no problems here.
So, off to make some plugs, find a gauge, and pump it full of
water (BTW, the wooden crate this came in had a little feed pump
in there, too. Bonus!)

I'd love to come across a paperweight like that one myself Bob!

Nice find Bob!
Looking forward to hearing the results of the pressure test.

This is a bit premature, but I'm confident.
Tested up to 120 PSI or thereabouts, but a nagging small gasket
leak kept reducing the pressure. Picture shows pressure at 7
bar, or about 105 PSI. No other signs of trouble, and I'll re-do
the test next week when I've made some more gaskets.
I'd like to run the boiler at 80 PSI.
Thought you'd like to see pictures.

Thanks for the pictures Bob, and I was just looking at those
same pumps on eBay the other day...
