Natural gas from the meter is regulated at 7 inches water column --
about 1/2 psi. If the meter can supply the required volume in cuft/hr,
it will run kilns and furnaces.

Tim,

I know it will run a furnace since I have natural gas. What I meant is
that I don't believe there is enough pressure and flow to properly run a
"foundry furnace" since you'll need about 30psi to get a flame. That's
my experience with propane for a 5 gallon style furnace and a Ron Reil
burner. So I would think you would need approximately the same amount of
pressure to run on natural gas. The foundry furnace I'm talking about is
al Gingery style. Now the 1/2 psi and a good volume with a blower motor
might work.
