1926 Engine/boiler combo

---------------------------------------------------------
Good Afternoon from Brooklyn..
Some time ago I took a chance on the engine/boiler
combo in the photos. It was built in Sept 1926 (engraved
on the base) and hadn't run in many decades.
Now, I've restored it to working condition (for now)
by fixing several problems w/sealing and a tough
steam chest/valve issue. I've left it mostly original
and it works for now. Won't guarantee tomorrow.
So, the original heater looks like something that
would get you arrested at the airport. I've seen
several blowtorches at work, but can't imagine
what was used for fuel.
There is a valve at the burner, another below it,
and the other end has a silver 'cap' something
with a valve at the top. If there was a pump, I
would suspect it needed 'white' gas (old-school
name for camping stove gas?), but there is none.
The tank, which looks homemade, has absolutely
no odor to give a hint. That's all I know.
I've added photos of the questionable burner,
the engine as received, as it is now, I couldn't
add the video - wrong type(?). Please note that the burner
I'm using is a weed-burner that works and looks like hell
but I would love to get the original burner working to go
completely old-school original. As the say on the baseball
field 'Little help?'.
Any Ideas?

earlier photos didn't get in.
I think I have the knack now.
Video for later.

Looks great!
Reminds me of my "Serious Boiler" (q.v. elsewhere on this site)

Hope it works out for you!.

That's what I thought when I saw the other.
FYI, 8oz just reaches the top of the flue tube.
The boiler is 3" by 7" and the flue is 1 3/4" in
diameter (bottom of flue about 1/2" above
bottom of boiler) and has 12 cross tubes.
When it came it was setup with a super-heating
loop, but that had to go to get this far. Cool
boiler, cool engine, happy steamer.

I can't help with your burner problem, Wayne but that is a
looker of a steam plant.
I did see a few Regner marine burners on ebay but they probably
aren't big enough. I hope you can get one sorted.

I will try to come up with a good looking custom
burner setup. Now that I know the burner
works I can mess around with the gas delivery
piping and try to make it resemble the original
even more. A nice, original condition runner,
is worth more in my book than a pristine mint
restored example.

Looking at your original burner makes me think of a Coleman
lantern. The “silver cap” is likely where you would fill the
tank with white gas or naphtha. Early Coleman pieces used a
separate pump to pressurize the tank. The cap has what looks
like a nipple on it where something could engage it. Check the
cap and see if it has a check valve in it that would let air go
in the tank, but not out. Once the tank is pressurized, the
valve at the other end would be opened just enough to let a
small amount of fuel through so the burner could be lit and have
a flame just big enough to heat the coil. Once the coil is hot
enough, it will gasify the fuel and have a nice efficient flame
at the burner. At least, this is how I think it should work.
Also very similar in operation to a gasoline blowtorch.

The 'nipple' is actually a valve stem, so, you could unscrew
the
top portion (w/valve stem), pour in fuel, and then replace the
top. Then, I could attach a pressure-source, open the valve,
wait for pressure to normalize in the tank and then close it.
The fuel tank would then be pressurized.
The business end pipe/valve is attached to the tank 1/2 of the
way up (other end, when the tank is lying flat). This leads me
to
a leap of logic. Since the idea is to burn a gasified vapor,
the
amount of fuel I use 'must' be lower than the level of the
outflow
pipe/valve. This is to avoid getting fluid fuel into the burner
system (does not sound good). So if I try it I'll load it maybe
to 1/3 of the way up from the bottom wall of the tank. Ah, but
at what pressure? Can't be too much. And, how clean burning is
Coleman fuel? Obviously, this is a 'NOT IN THE HOUSE, EVER'
burner.
That said, I'd love to see at least the burner work one time so
someone
else down the road can opt to restore it to an oroginal setup.
As for me,
propane and a weed-burner head worked well.
So, I'm glad to hear other thoughts on this.
Still in one piece,
Wayne

Liquid fuel must leave the tank to reach the coil at the burner
in order to be come gasified. Same way a Coleman lantern or a
gasoline blowtorch works.

Well, O'k. I'm up for this. How many pounds of pressure do
you
think would be adequate? As soon as I can get some Coleman
gas I can give it a try.
Can't believe I'm up at this time. Trying to communicate with
a
German auction house regarding a Bing I won. Seems to be bit
of trouble keeping their attention. Supposedly my VISA won't
work
but VISA never received the request-for-auth. Hmmmm. Maybe
PayPal will work if they give me their info.
I'm getting frustrated by this lockdown,
Wayne
