For what it may be worth, last year Vermont Castings/Majestic came out with a new non-catalytic burn chamber design which they call "EverBurn". They claim much longer burn times with this burn chamber design as compared to other brands of non-cat stoves. Anyway. if you are really interested in this stuff, you should certainly stick your head into a Vermont Castings stove with "EverBurn" to see the design. Let us know what you find - tubes? baffles? or ?
The reason I mention this is that it appears that Vermont Castings has winner with the "EverBurn" burn chamber as they are selling a lot of stoves with EverBurn.
Harman also has a secondary burn chamber in the back of their stoves. Must be similar to VC's.
