<div dir="ltr">Hi Stovers,<div><br></div><div>There is a point in the TLUD process that I find specially difficult to understand and control: the transition from wood gasification to char gasification. Maybe you can help me to do it.</div><div><br></div><div>At this point, <span style="font-size: 15.5555562973022px;"> when </span><span style="font-size: 12pt;">the hydrocarbon fuel is near to finish, </span><span style="font-size: 12pt;">my experiments with almond husks as fuel for ND-TLUD shows 2 possible endings:</span></div><div> 1- The flames in the burner turns to blue color (due to high CO presence in gases) and the char pyrolisis continues until ashes. No smoke present.</div><div> 2- The flames in the burner extinguishes and the smoke appears.</div><div><br></div><div>I made a lot of tests, with variations in ND-TLUD design (riser height, quantity of primary and secondary air, type of concentrator, etc.) and still I'm not able to say which factor combination is the answer for a smokeless transition. Sometimes I have smoke, and sometimes I don't. </div><div><br></div><div>I suspect the answer has to do with chemical fuel composition, as w<span style="font-size: 15.5555562973022px;">hen I use wood pellets, almost never have smoke.</span></div><div><span style="font-size: 15.5555562973022px;"><br></span></div><div><span style="font-size: 12pt;">So this is the point where I am today. When char gasification begins, I have to lower the primary air? Lower the secondary air? How I can ensure the flame won't extinguish?</span></div><div><span style="font-size: 12pt;"><br></span></div><div><span style="font-size: 12pt;">It would be very useful for me to read your comments about this.</span></div><div><span style="font-size: 12pt;"><br></span></div><div><span style="font-size: 12pt;">Thanks very much,</span></div><div><span style="font-size: 12pt;"><br></span></div><div><span style="font-size: 12pt;">Marc</span></div><div><br></div><div><br></div> </div>
