No this seems to be a holding page now. 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.
