Not necessarily, because you need more air to have enough oxygen. Either
one can make a hot flame. If you run propane in a natural gas device I
would think you would get a yellow sooty flame. If you run natural gas
in a propane device it might not even burn. and will be feeble if it
does. But each makes the same btu/burner in an appropriately designed
appliance.
