I am entertained easily with simple things...<br><br>Pits happily act like ball-bearings in a feed system. <br>To utilize a paste-like mass left over from mechanical seed-oil extraction, an extrusion of the waste paste could be metered into the maw for co-combustion with pits.<br>Most places in the world do not have cherry pits. So a special refractory "grog" could be heated, and circulated to burn gooey pastes alone.<br><br>Please wear eye protection when gasifying stuff,<br><br>Andrew Schofield<br>Renewable Fuel Systems<br><br><br><br><br><br><o:p></o:p></span></p></div></body></html>
