Are you saying that if insulated, and hot enough, that the
pyrolysis reactions will give sufficient H2 and O2 to combust
(become simple water) even into the center of very thick logs? <br>
<br>
I will allow for some (but not massive fire) extra external heat
to be added as needed, because the NET heat of pyrolysis and this
combustion is endothermic (slightly). I also allow some extra
heat because the biomass will not be totally dry so some heat is
needed to bring up the temperature of that inert H20.<br>
<br>
Other issues: What about all those other tars and oils and vapors
that are combustible but for which there is not sufficient Oxygen
inside the biomass molecules? Are you expecting this to drain?
Or to remain inside the "char" that would be loaded with such
"gunk"? That would be interesting char for burning, but not as
biochar for soils and plants.<br>

<div>Biomass contains enough Oxygen to seed its own destruction.
All you have to do is heat the log and keep it insulated well
without O2 getting in.</div>

<div>It will burn almost all the Hydrogen and char the entire

<div>Within the fine print in your fine report, I found, "<span

Sans',sans-serif;font-size:12px;line-height:18px">To
confirm this claim, the author, during his field research
for his master’s thesis, went up to the forests of
Barangay Bulala in Sta. Elena to observe the traditional
practices of wood charcoal production. There he found
several piles of huge dirigkalin logs ready for the
carbonization." Could you find how they carbonize HUGE
logs? What is huge and do they down size them before
carbonization? Since most of us, including trees, will
eventually fall and many are of no value for lumber or
firewood, it would be helpful to know if someone is
charring hug logs. The largest I have received at my
farm/compost site, is a cotton wood trunk, 7' dia. X 15',
which I would gladly donate to whatever. </span></div>
