Natural Gas Process Heating

Natural Gas Process Heating

Natural Gas Process Heating

(OP)
We are looking into converting from LP to Natural Gas to heat tooling.  We currently use 6-8 large "Weedburner" torches burning LP.  In the past, natural gas was experimented with here, rings were fabricated from Ø1" black iron pipe, rolled to approx Ø28" dia, and drilled and tapped with orifices screwed in.  There was no air mixed with the gas prior to the ring, and the flame wasn't hot enough for the process.  Could a blower be used to introduce/mix air with the nat gas in a chamber attached to the ring to increase the flame heat?  Where would be a good starting point for such a design?
Orifice size?
# of nozzles?
CFM of blower?
Chamber size?
ETC...?

Thanks

RE: Natural Gas Process Heating

I'm not sure, but I beleive you will need to change the orifice sizes to account for the different wobbe index and Weaver indices of natural gas vs LP gas.

I think you should leave this entire modification up to the manufacturers of the "weedburners".
