The fines behave a bit like a thicker piece and will </div><div>pyrolyse from the heat after the pyrolysis front has passed. If the fines tend to sift down to much into the regular fuel then a 2cm wide strip of</div><div> paper could be laid down to act as a floor for the fines. Trial and trial will show you what size of pile and how far from the bottom they </div><div>need to be for it to work. As long as the surrounding fuel is porous the falling pyrolysis front should proceed passing by the piles of fines.</div><div>Gas production will vary somewhat when compared to using only optimum sized fuel, but it can still work.</div><div><br></div><div>Alex</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Dec 16, 2014 at 9:08 PM, Richard Stanley <span dir="ltr"><<a href="mailto:rstanley@legacyfound.org" target="_blank">rstanley@legacyfound.org</a>></span> wrote:<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word">Marquitusus,<div><br><div>Here is a hand thresher-masher-chopper device we have been developing initially in collusion with a colleague in the US (Ohio) then in Guatemala and now in Nicaragua with contributions from colleagues in Kenya and the Philippines who are developing their own versions. </div><div><br></div><div>We use it for reducing and scruffing up materials for use in biomass briquette production but by removing the wire brushes you will have a simple thresher-chopper that would nicely reduce the shells to a desired maximum size.
