Dear All,yes, its better not to use "smouldering kilns", but "retort kilns" instead. 
However as long as ring kilns are used, the "box-kiln" might be a better alternative,because a "box kiln" can be easier fitted with some insulation (= better efficiency) and also they are more suitable to fit an "afterburner"?I do not have an own workshop, i paid all expeneses from my private pocket to build this prototype.
So let see if we find some organization which funds the 2nd stage to modify and integrate an "afterburner" in it?CheersChris ADAM

 I take Frank’s message to contain a concern for the excessive smoke with Chris Adam’s kiln.   I agree.
 Chris - at 2:30 of your video on the box kiln,  there is a note saying that one can add an after-burner.  If, you’ve done that - can you send anything on the improvement?

Interesting images on this book cover :
https://woodsmithexperience.co.uk/product/making-charcoal-and-biochar-a-comprehensive-guide 
…”There are chapters on the heritage skills of earth burns, the enduring popularity of metal kilns and the future represented by the charcoal retort.
Biochar – or small particle charcoal – is heralded as an ancient but rediscovered ‘super substance’. It can increase soil fertility and productivity whilst locking up carbon into the ground. This book looks at the ongoing discussion and weighs up the evidence.”…

>From my personal and practical experience over the past 13+ years on this topic, the  big difference between the classic charcoal ring kilns with lid, air inlets and 4 to 6 pipe chimneys (I have a big one, but it became obsolete for us some six and a half years ago),  is the air pollution / smoke emissions, condensations and lower carbonisation temperature.
When I  compare this old fashioned smothered, “smouldering burn” with the optimal open burn, in deep cones & ring kilns without lid and without condensation we get very different results.
When it comes to Biochar for soil improvement, quenching with nutrient rich liquid (if available) or water will result in very different products to snuffing the char dry.
The particulates from black carbon / dust is another reason why I would not suggest to hold on to this practice. 
Producing dry charcoal for fuel (carbon oxidisation) as the main / primary product objective  is therefore fundamentally different to the intentional production of high quality, fit for soil medium purpose, soil conditioners and  nutrient enriched Biochar.
The debate and the action continue, and that’s just fine …

Subject: Re: [Biochar] Box-Kiln for improved charcoal production, Adam 21.12.020 Youtube  Flattered that my company VUTHISA is being mentioned in the video. Just have to point out that the small TPI metal kiln pictured is actually being sold by a UK company: https://woodsmithexperience.co.uk/product-category/charcoal-kilns-equipment/page/2/  Also note our kilns are now all being lined with various types of insulation so we don't advocate using a system where any part of the flame interacts with a metal surface similar to this pizza oven: https://vuthisa.files.wordpress.com/2020/12/20201130_131434.jpg an example of a refractory cement cast in a mould.   I really love the ideas coming from Chris Adam - we often talk and exchange ideas - that's the way it should be.     Wbr  Kobus
