Dear Alex,<br>
I really like this. It may be at least part of a solution to the
problem that I originally joined the stoves list for several years
back. <br>
<br>
My assumptions:<br>
only natural draft<br>
passive feeding/gravity<br>
no draft control other than pipe diameter limits<br>
<br>
true/false?<br>
<br>
regards,<br>

P.S. I constructed something a bit like this to vent hot, wet air
from my clothes dryer to the outside without boring any holes
through my rental apartment's walls. I built it to press fit into
the German-style tilt-from-bottom-hinge/open-as-door window. It
served well until the dryer gave up the ghost and was replaced by a
dehumidification type dryer.<br>

Its a long winter, and old bones and cord wood and Crispin make me
think......
<br>
<br>
Attached are two pictures which show my early steps towards
understanding the limitations of gravity with stoves.
<br>
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.
<br>
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.
