[Terrapreta] SIMPLE CHARCOAL PRODUCTION TECHNOLOGIES

[Bruno M.]

Hi Len,

Good links and info, maybe you have some wrong linking of "type of files" with applications on your PC?
These links all worked as promised:

http://charcoal.fw.vt.edu/charcoal
And the link on that page to a 6 page PDF document of " How to make a charcoal kiln" is:
http://charcoal.fw.vt.edu/kiln-design.pdf
And this, also works fine:
www.cd3wd.com/CD3WD_40/VITA/CHARCPRD/EN/CHARCPRD.HTM

If the first link is a problem for your browser, please click here:

I prefer the old design with the smooth sides, but if you have a small grain bin lying around, it would be cheapest.  It also includes "house catalytic converters for reducing air pollution during

>>I want to make it similar to our top draft earth covered pile of last year where we pyrolysed about 1.5 cords in one burn ( after 3 tries).  This season I will do the same with a stainless restaurant hood that will let me stack about 1 cord. This year I have a endless supply of pallet boards cut to length by a local recycling company. There is a lot of oak and tropical hardwood so will make high quality charcoal.

>>I think where I am going with my idea this year is similar to the New Hampshire kiln, ie an appliance that can be lifted off with the tractor. I do not think it is necessary to do the elaborate welding for this bottom draft system as if there was a bottom segment that the hood sat on such as a berm  of soil, then the drafts could be dug in where needed. I think there also should be some holes made  in the hood with 1" pipes for management of combustion air.

>>The Montserratian 'coal' pit is interesting because it has indeterminate length. I think a hybrid of this idea with a top draft system is where I am going . A small  tractor/bucket can easily scale this to any size for infield work. 
>>
>>My observation is that the stacking method and allowing for circulation of hot gasses inside the pile is important. We used pallets for base on a series of channels dug for circulation. We had considerable contamination with soil from our earth covered pile that came mainly with pile unloading. I think movable and easily transportable panels up against a layer of wet cardboard then hay would be the ticket.
