Very interesting and the TChar should be fully explored and I follow your progress with interest and well done! I had a similar Eureka! moment the other day when I decided to turn my Barbecook Optima Inox (http://www.barbecook.de/en/products/charcoal-barbecue-detail.asp?refnr=2234302000) from Belgium, into a TChar of sorts. <br></span></div><div><span>See attached pic or click on http://vuthisa.files.wordpress.com/2012/08/barbecook1.jpg In conventional use, newspaper is stuffed down the shaft; a circular perforated plate then closes up the shaft to prevent the charcoal from falling in to the 'internal chimney' and charcoal is stacked on top in the bowl. A match is inserted into the air holes in the shaft to ignite
the paper which then ignites the charcoal. I turned it into a TChar by retrofitting the shaft with one of my patented ceramic liners. I burned about 12 briquettes rather non-efficiently on top to turn it into char, half of which I 'broke' into pieces that would allow good flow rate and dropped it down into my ceramic chamber. I inserted a StoveTec cast iron top into the bowl and placed the plate over it to prevent the briquettes from falling in and to allow for airflow. I then had some flame grilled chicken</span><img src="http://mail.yimg.com/ok/u/assets/img/emoticons/emo1.gif" alt=":) happy"><span> The point I wanted to make with this adaption is that you can make your own Legacy briquettes at home from paper and sawdust or leaves whatever and have a barbecue with it; and in my case I also gasified most of the char. I made a video some while back of a Barbecook charcoal gasifier which I recently uploaded to YouTube:

I did not address it very well with this Barbecook, but I made sure to limit the primary air through a high draft chamber which had the desired result albeit with higher amounts of CO but that got burned off by the Barbecue flames/fire/coals above.</span></div><div><br><span></span></div><div><span>Regards</span></div><div><br><span></span></div><div><span>Kobus<br></span></div><div><br><span></span></div><div><br><span></span></div><div>www.vuthisa.com<br>

Dear Kobus, maybe I should answer this: the fuel was douglas fir, natural logs stacked vertically in the combustion chamber (not the thin 1x4cm kiln dried pieces).<br><br><SNIP><br><br><br><br><br><br><br><br> </div> </div> </div></body></html>
