[Stoves] Addendum: 64% coverage

I don't see a gap. Or are you just showing is the two diameters?

The gap is 63 cm2 which is about a 90mm diameter hole. That is plenty big.
I'll bet you can cut it in half. Try a disk of 140mm. Cut it 145 and hammer the edge over to make a small radius of about 3mm instead of having a sharp edge. It will increase the velocity without costing you much in terms of draft.

This shows the relationship of the 12 cm diameter disk to the 15 cm diameter pyrolysis surface. It also illustrates the relative size of the gap the pyrolysis gases must pass through to enter the combustion chamber
