[TheForge] Natural gas burner?

[Bob Willman]

	I have negotiated with the local gas company for 15lbs pressure. I
had to buy the regulators after the first one at the meter. I also had to
buy the meter which was $160.00. The pressure in the shop ended up at 12lbs
according to my guage. I do have the advantage of a high pressure gas line
along the road in front of the property. The gas company was very
cooperative when I made the request.

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.

If it ain't forged
it ain't real.
Wrought iron is.
