<div dir="ltr">Dear Crispin<div><br></div><div>I use stainless steel rods 8mm with gaps of 8mm. This allows the pilinut shells to fall off after it has fully carbonized. Will adopt the idea of the tilted grate 20 degrees. </div><div><br></div><div><div>Also Im struggling with TEGs. Its an amazing project and still cannot get it started. I suppose it would be very easy to simply embedd the TEGs into the clay wall and poke the wiring out to a fan or a charger. Could you please tell me more. about this..</div><div><br></div><div>News on the side.... im contemplating about joining a humanitarian mission next week. There are close to 3,000 refugees that fled from a conflict zone. The place is Tandag in the province of Surigao del Sur. Their tribal leaders and their teacher were executed by a paramilitary group who was organized by the Philippine Army.. the evacuees are in a sports complex. My friends are going for a feeding mission. am raising some funds for my plane fare. also thinking about bringing my stove and have it tested there... .. to cook, to make bio char.. to use the biochar for sanitation.. to make compost,.... to teach people on approtech.... <br></div><div><br></div><div>Regards</div><div><br></div><div>Jed </div><div><br></div><div><br></div><div><br></div><div><br></div><div><div><br></div><div><br></div></div></div></div><div class="gmail_extra"><br clear="all"><div><div class="gmail_signature"><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div dir="ltr"><div><div><b><span style="font-family:garamond,serif">Joshua B.

In the set of drawings on my website (Library/Stoves/GTZ7) the grate is not tilted enough. It should be about 20 degrees at least. The far end is upturned a little to catch the coke/char and not let it pile up against the far wall. </div><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)"><br></div><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)">The TLUD fire is built on top of the grate perhaps 250 mm high. The final version has a 50 watt 12 volt TEG on the heat exchanger with two computer fans cooling it. The idea is it can run a TV and lights. </div><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)"><br></div><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)">I found in experiments at YDD that the grate for wood should have quite small gaps - 4 to 5mm. It really reduces the char loss in the ash. For reasons which are not clear, round bars accomplish this better than flat upper surfaces. Still thinking about that. </div><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)"><br></div><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)">Regards </div><span class="HOEnZb"><font color="#888888"><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)">Crispin </div></font></span><span class=""><div style="width:100%;font-size:initial;font-family:Calibri,'Slate Pro',sans-serif,sans-serif;color:rgb(31,73,125);text-align:initial;background-color:rgb(255,255,255)"><br></div><div><div dir="ltr">Dear Crispin<div><br></div><div>I just realized now reading from your remarks... that what im doing is a cross draft gasifier.

The fresh fuel either comes on the side, or on the top of the hot char bed. But wood sticks can be poked under the hot char bed and they give better results. </div><div><br></div><div>Im writing a narrative of the details of the anatomy of the stove as Dr. Paul requested.
