Dear AD,
Thanks for clarifying this issue that I mentioned in a msg to the list,
evidently whilst you were composing this one.
regards,

Dear Tom,
our charring kilns are used primarily for light biomass such as dried
leaves, paper waste, cardboard, threshing floor debris, pine needles,
straw, etc. This material is too light to be transported to a central
charring unit. Therefore the user takes the kilns to the place where
the biomass is lying. A kiln accepts about 6 kg of such waste
and takes about 15 minutes to char it. Since these are portable units,
we dont bother to get any useful heat out of them. The material is not
packed into the barrels, as it would obliterate the air flow. It is
placed only lightly inside the barrel. If the operator finds that the
material is obliterating the primary air, we advice him to reduce the
quantity of material placed in the barrel.
Yours

AD, Paul, Kobus and others. Many thanks for the suggestions.
What is the largest practical size (kg fuel/hr, kW) for a single
TLUD with a clean stack for heat recovery? There must be a limit
to the air penetration to get a clean gas burn form a natural
draft stack or even a fan driven TLUD.

Dear Tom,
we regularly supply charring kilns made out of used 55 gallon
drums. The kilns are based on the TLUD principle. The cost of a
kiln plus an extra barrel for storing the char, is about
US$100. We have sold more than 100 such kilns in India and have
also trained a number of persons from India and Africa. These
kilns are so easy to manufacture, that we ask the trainees to
photograph and take measurements of our kiln so that they can copy
the design. In many instances, people buy a kiln from us, because
they feel that their local fabricator would be better able to copy
the design from an actual object than from a blue print or a
photograph.
The advantage of using 55 gallon drums is that used drums are
available at a relatively low cost, and the kilns are portable.
Instead of transporting the biomass, one transports the kiln to
the location where the biomass is available, and brings back only
the charred material, which weighs only a third as much as the
biomass.
Yours
A.D.Karve

Am often asked if there is a burn barrel sized TLUD that is
commercially fabricated. We’ve seen some great DIY with Doug’s
Jolly Roger and others. Is anyone fabricating a 55 gal drum sized
TLUD that can be used for regular biochar production? If so, what
is the cost and availability?
Thanks
Tom Miles
