True,
I hadn't really considered any shape other than the typical tapered
cylinder. I was getting held up on that rather than considering the
actual burner and flame holder.
I would think that the burner needs to be little more than some small
jet to allow the natural gas to pass through at residential gas
pressure (~4 inches of water -- I'll verify) and a flame holder which
looks to be little more than a perforated metal cup.
Thanks for helping unblock the brain!
