No matter because I remember the discourse from a couple of years back. Firstly if allowing all the combustion air through the hole works well enough to my mind that's good enough. What I was trying to get was a bit more control, now generally you need to pass about 6 kg of air for every dry ash free mass of biomass. If you pass all this air through one whole you probably don't have any means of preventing too much primary air and a possible runaway condition which can only be controlled by removing fuel. With Rok's configuration I would expect there still to be too much air. What I wonder is if the briquettes could be fed onto a tube through which the primary combustion ( from air passing between the hole and the tube with a separate control) could induce secondary air moving the secondary combustion slightly away from the briquette.
