The galvanized cover I put over the air intake holes, keeps chaff from falling in, warms the incoming air more, but along with the 90 degree angle in the 4 pipes, makes it more difficult to be sure they are clean.</div>

Suppose it would need a bypass door, to open, when fueling. </div><div><br></div><div>The 30' X 10' dia. 1" thick rr tank car, shown last, in the biochar video, is still waiting for a cheap, efficient plan, for top loading brush, to produce heat, biochar and possibly energy. Any TLUD ideas that might fit? Thanks, Dick</div>

<p class="MsoNormal"><span style="font-size:11.0pt;color:#1F497D">As before, I note that because there is such a large open space inside the back of the stove. I say ‘open’ because when the fire is small, it is as good as a partially heated open space. </span></p>

The heat and flames will be filling in the space at the back. When the fire is smaller, smoke and CO can get around the flames at the edges. That is what I was referring to when I say it needs a combustion chamber.</span></p>

The modified traditional Mongolian stove has instead a pipe which accomplishes the same thing. It would be interesting to know what happens of some sort of conical burning chamber were inserted immediately after the fingers that separate the fuel from the flames.</span></p>

Hi Crispin,</p></div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">It would be a cross draft, with the preheated primary air coming down through the 4, approximately 1" pipes, that enter a few inches from the base. The pipes have a right angle and I mentioned to Bruce Wolfe, who was just starting USA Sedore, that the 4 pipes would be easier to clean, if the right angle was eliminated. He agreed and said it would also be cheaper, so may have changed that. My 4 pipes must be partly or completely plugged, in that it is always run wide open and we usually have a nail or large bolt holding the feed door partly open, making it a down draft. It has an 18' straight stack, with insulated stainless on the outside, so draws well.</p>
</div><div><p class="MsoNormal"> </p></div><div><p class="MsoNormal">There is no grate, just a few fingers protruding half way down, into the approx. 3+" gap across the width of the floor of the firebox. It couldn't be much simpler or efficient, yet all my long gone farmer neighbors, heated with the most in efficient wood stoves and furnaces, often with large, uninsulated homes. </p>

In that case it is a Crossdraft stove with the primary air coming in from the front and passing through the fuel to the back.</span></p>
