Ribbon burner for demo's

I could also have a little debris in the plenum, because, like a dumb*ss, I didn't take the paper off the crayons like I
Is the cross sectional area of the crayon burner ports larger than the supply pipe? If you don't keep increasing the area you can run into back pressure problems. It's also a pretty large volume to heat with what appears to be a small burner. (Small by burner port cross sectional area. Sorry for the long descriptive.)
On the other hand it sure looks like a nice even temp. Bet it'd make a dandy heat treat oven.
