[Stoves] Heat / cook stove - proposed design

[Darren]

Hello Richard.

Yes I'm using an air feed from below the grate.  The hopper lid was 
designed to be air tight.  Its made of heavy steel plate welded onto 
some thinner metal strap that is on edge, this closes down onto some 
asbestos rope that is sat in a channel.

I'm not sure if it is completely airtight.  When I was burning wood chip 
in the stove I noticed, once, that the fire had spread up into the 
hopper.  I guess time will tell.  I have been considering fitting some 
kind of latch to pull the lid down tight onto the rope.  I've done this 
to the front door since I took this picture during the first test burn 
in January.

Long a go in this list there was mention of a Canadian inventor who developed the idea of back feed like your stove. Anybody recall the person ? Maybery ?   Another person, from the US part of the Americas , tried the same idea with vertical stacking of the fuel (in this case hollow core briquettes) and had pretty good success as long as the hopper lid (feed tube in the case of the briquettes) was absolutely kept airtight. In both cases air feed was thru separate vents, not the hopper.
