What about doing the p-channel as a round opening through which a steel pipe is suspended into the burn tunnel?
Could the pipe be smaller in diameter than the opening if the total size of the opening allowed for the wall of the pipe? Pipe would extend below the burn tunnel roof and above the feed tube plane just as recommended for the plate-style p-channel. Seems to me that a pipe would remain pretty stable in the heat relative to the warping of metal plates.

Hmmm... In my view, you do need (warm) air injection the full width of the burn tunnel ceiling. I've tried one in each corner but this layout didn't work as well as the full width gap. The corner layout happened to be slightly larger as a whole.

So, add O2 then interrupt laminar flow?
