Adam Box-Kiln (new)
A new Box-Kiln was developed in 2019/ 2020
more information will follow soon....
The main advantage of this
Box-Kiln will be that only one person can operate it.
The weight to lift the cover is reduced to about 30kg- thanks to the counterweights
Starting the Box-Kiln operation by enkindling a fire in the front.
A one-day operation is possible
2 detachable insulation lids are placed on the top to increase the efficiency of charcoal production.
Further insulation lids for the 3 sides are optional.
Comfortable loading of the wood
and
comfortable harvesting of the charcoal
thanks to the removable cover.
"It's fun to operate this kiln!",
-once you lift the cover- You have a gift of charcoal to your feet!
Steel Ring Kiln (MARK-II)
widely promoted by
FAO, UNDP, WORLD BANK, etc.
but never really accepted by its owners...
A Ring Kiln needs several people to lift the cover or the lid.
It's an arduous task to climb inside the vessel and to load
or to harvest the charcoal.
This Box-Kiln should replace the Ring-Kiln made from a round metal sheet.
This Box-Kiln was filed under Intellectual Property Protection and it should not be build without the inventor's consent (Ch.ADAM).

| disadvantages | advantages | |
|
Complicated Construction: needs a sophisticated metal workshop, as a roller-sheet bending machine is needed to bend large metal sheets into a circle shape. |
Simple Construction: simple construction in any village workshop, just (extensive) welding and no sheet needs to be cut. |
|
|
Operation by more persons: it needs 2 or more persons to lift and remove the lid and upper ring of a round steel ring. |
Operation by a single person: a single person can tilt the Box-Kiln because of the counterweights to ease tilting (option: if money needs to be saved, skip the counterweights) | |
| Biomass (wood) needs to be cut short into short pieces of different length- according to the variation of a cross-section of the kiln. | Biomass (wood) can be used in one standard length (about 2 meters). | |
|
Medium efficiency which is not really enough to justify and benefit all the investment |
Higher efficiency because of the top of the Box-Kiln can be easily insulated by a removable lid/cover. For quick cooling, the lid/cover can be removed. |
|
|
Medium volume (2,5m³) for filling with biomass |
High volume for filling with biomass, about 4m² if 1m x 2m metal sheets are used |
|
|
Difficult access to recover the charcoal, as the charcoal needs to be taken out from the deep hole if the kiln. |
Easy access for loading the biomass and offloading of the charcoal, as the box will be tilted upwards to ~90° |
|
| dt. | With some small modification- trials for an integrated afterburner within the box can be made- for clean combustion of the wood gas | |
| dt. |
Box-kiln can be loaded on a pick-up f transport |
|
| dt. |
Quick construction within a few days |
|
| none |
Already registered under the “Intellectual Property Law” to save the project's investment.
