[Stoves] Russian charcoal kiln (was Stoves Digest item)

[Paul S. Anderson]

Yury and all,

Good posting, and raises the question about the environment, and business
(profit) and cooperation, and the developing countries.

I have some questions and observations:

1. Question.  The gases, etc from the charcoal-maker are used to make the
charcoal.  Does your system use all or what percentage of the heat 
created from
burning the gases?  Where do excess heat or gases go?

2.  Observation:  In Nicaragua last year I visited a rural area with ProLena
people.  At one stop we saw a single-cylinder operation similar to what you
have in much larger form.  They used a winch to raise and lower the cylinders
into the brick-made kiln.  Cylinder size was about 1.6 or maybe 2 meters
diameter and probably 3 meters tall.  It was not in operation, and had 
not been
for a few months (was vandalized, I believe).

3.  The developed nations such as Russia have different budgets and even uses
for the charcoal produced.  Just having a great technology does not 
mean people
or nations will reproduce it.  That can be unfortunate, as you point out.

4.  Personally, I work on the TLUD (top-lit updraft) pyrolytic gasifiers that
also produce charcoal as a co-product or by-product when making usable 
heat. These TLUDs are much smaller, like Tom Reed's that can be held in 
one hand. But the principle of making charcoal in a TLUD style should 
apply also to
larger scale operations.  I spoke with and visited Dick Gallian (misspelled, I
think, and I cannot get to my file at this moment) in Wenona Minnesota 
a couple
years back.  There were some differences, but what was discussed was 
even bigger
than the individual cylinders that Yury has.  I am confident that the system
would work.  But neither Dick nor myself had the funds to implement the 
idea. My point is that large-size TLUD processes should be viable, and 
could have
reasonable costs, IN MY OPINION.  But until someone actually will sponsor such
a project, there will not be much progress on this aspect of commercial
charcoal making.  Perhaps a small "task force" could further discuss these
prospects.  I hope that Yury and Tom Reed and others express interest.  I am
quite interested.
