Stovers,
Its a long winter, and old bones and cord wood and Crispin make me
think......

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.
