Is there an advantage to the round or spherical combustion chamber?
Yes! A spherical combustion chamber is the single most important factor in proper combustion. The general engineering design rule is simply that round is better than square in combustion chambers. This is true in our car engine cylinders, jet engines, better kilns, furnaces, and a properly designed wood stove. This is an easy choice from a design point of view, but a difficult choice from a manufacturing perspective! A good sphere is very difficult to make. But its essential, so weve mastered the art of doing it. You will be rewarded by seeing the proper circulation and mixing, and the complete combustion resulting from the spherical design, or when viewing the flames through the glass. Or, more important, when you and your neighbors view the emissions from the top of your chimney..nothing but clear, smokeless and clean emissions.
