[Gasification] brush to charcoal

[Robert Kana]

Hello Joshua,

I know there are acacia plantations in Indonesia and doing very well 
with the yield. Acacia is hard wood make good charcoal. Freshly cut 
acacia will yield about 20% charcoal, 2 months air dried acacia will 
yield about 30-33 % charcoal. No matter where you are firewood is about 
$ 50 per ton, compare to charcoal at $ 300. If you can make the charcoal 
in retort, yield will be more, you can also distillate the smoke and get 
100 liters of wood vinegar from 1 ton of wood being carbonized. Wood 
vinegar can be used in soil improvements as well as charcoal dust that 
you will get from your charcoal production.
There are other valuable advices what to do with the land, if you 
consider to go with charcoal we might be able to give you some ideas how 
to do this in an environment friendly way. To produce energy with the 
wood you must compromise on charcoal, but you can get biochar.
There is no easy answer to produce energy (thermal-electric?). All 
gasification systems to produce electricity is costly. The only way to 
make charcoal and electricity, you built closed retort systems with gas 
diverting pipes (these pipes will get dirty with tar), wood gas coming 
from the retorts can produce steam for turbines. Now we are talking 
steam boiler and turbine. If you go with an IC engine, there is a 
gasifier, gas cooling, cleaning, filtering and IC engine.
Anyway we can help you with the carbonization and biochar production. 
For gasification for electricity (our gasifier produce biochar instead 
of ash), you can e mail me directly.
