Alex and list: Nice looking and clever wedge idea. Congratulations. Have you seen anything similar as a retrofit?
Can you explain the functions of the small port below and the larger port "up-wind"? This doesn't produce any char ? We are looking at about an 8 kW flame? Can you vary that by varying anything? What is chimney height? Where/how does the ash get handled?

Attached are two pictures which show my early steps towards understanding the limitations of gravity with stoves. One shows a wedge shaped door spacer "the Artful Dodger' which picks the stove's pocket for draft and connect it to any burner idea I can cobble together. The other shows it operating with a burner that has a small unsealed hopper for pellets. I use a loose lid/follower to ride down on the pellets. So far there has been no fumes coming up and out, and the fire has not chased the air and fuel back into the hopper. The bottom throat on the hopper is about 5 cm diameter. It operates continuously at one speed with an input of 1.6 kg of wood pellet per hour.
