[TheForge] Natural gas burner?

George,
You did luck out. If I had been watching you would not even have been high
bidder, shipping or no shipping :-)

  Thanks to Frosty, Rick and Mike (in order of response) for the
input...pretty much as I had anticipated for the final answer...Trial and
correction until satisfactory results are achieved, as seems to be the case
with any homemade burner tuning endeavor.
  On a side note: I wasn't really looking for that particular unit when I
found it...not sure what, exactly I was browsing for but it caught my eye,
so I did a little Googling and was able to figure out that it would probably
work for what I needed (fuel source for flame cutting and forge) and was
located close enough to go and pick up so I wouldn't need to worry about
shipping.  The guy I bought it from said that he had gone broke twice trying
to sell the units and still thought they were well made and a good
investment for a shop that uses a good amount of fuel gas.  He had said a
couple of times that I'd gotten a "hell of a deal" on the set-up, so I
finally asked him how much the rig sold for...He said "About $3000."  which
jives with the limited amount of information I was able to find.  He also
threw in a couple of torch bodies, a couple of rosebuds, a set of guages and
a handfull of cutting tips.  I was really surprised that I was not only the
high bidder, but the only bidder!  Just got lucky on that one.
George.

Good score George,
Those units are not cheap! You can get plenty of information on torch tip
differences through any of the big manufacturers who have sold torches to
railroads in the past; they ran on natural gas at one time; may still.

I didn't wish to pay through the nose to get compressed methane in order to
do burner experiments with it, since almost no one has high pressure methane
available anyway. But, its air requirements are less than propane's so the
same burners should work fine if you just do some MIG tip size changes until
you find the one that works best. As to complete primary flame combustion
with methane, it is not likely, but who knows until you try?

You'll need a larger orifice in the jet and a regulator. You'll need to
tinker with the orifice size but it'll work just fine.

it ain't real.
