This rotating burn pot???
Is that the key to keeping the clinker small enough to remove via the ash pan
vs what I am used to with my big old Iron Fireman --- busting the clinker into manageable chunks, and picking them out thru the fire door
I would assume less than complete combustion of all material if not allowed to cook on the plate long enough. Is that now simply a matter of fuel input control vs combustion air to vessel performance under variable load.....
Wouldn't simpler be better???? Just burn the bit coal into a clinker tower and tend to that clinker twice a day. Make the appliance user friendly to that end ---- have the fire door hi enough and large enough so the user doesn't have to stoop too much to see in and the chunks can be easily picked out!
Maybe I am simply too old school or still lost in my past. But just random thoughts to pass along - please don't anyone be offended! I would tend to wish to burn the cheapest fuel I can find in the cheapest fashion to the highest return of BTU out per dollar spent in - others -- maybe the larger market for these appliances, would want more "automatic" operation.
