This radiative feedback is probably important, there were experiments with lots of different shaped holes by the early pyrotechnic rocket pioneers with this hole shape for solid propellants.

Which is what happens with a tlud stove if you think about it, the difference is the space between the end of the briquette and the pyrolysis front is kept oxygen free. The question is how uniformly does the fire creep back in a horizontal feed.
