[Stoves] The upside of Down feed

[rongretlarson at comcast.net]

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?

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.

May you find inspiration in the foolishness of others.
