Chopped Wood

Woody Biomass Supply Chains, Potential Alternatives to Charcoal

16 April 2013 - 10:39am

In their presentation at the GACC forum, Paul Means and Chris Lanning take a look at the supply chain problem with using woody biomass as a replacement for charcoal in urban areas, and they propose some ideas for equipment that may overcome those problems, as well as identifying some of the challenges to that approach.

They have developed a various biomass stoves ( Kompor Biomass ) The fuels also vary from chopped woods/twigs, pellet, palm kernel shell, hazelnut kernel shell, corncob, etc..

And they have a nice collection of YouTube videos:

All stoves presented above are of TLUD types, but the combustion is improved by using pre-heating and counter-flow burning mechanism. The one intended for palm kernel shell utilizes diffused-combustion mechanism, in addition to pre-heating and counter flow mechanism.

The latest one

is devoted for institutional cook stove or small restaurants.

Very recently, we have also developed a new rocket stove. The combustion in this new rocket stove is improved by introducing counter-flow burning mechanism.
