A loaded kinyanjui type barrel kiln carbonizing maize cobs
free fuel!
a full kin of maize cob and branch charcoal made in less the a day
the maize cob charcoal cooks with high heat and little smoke.

Four very good reasons why to make your own charcoal from dry maize cobs.

  1. They are FREE!! (minimal processing required and are widely available as a farm waste product)
  2. Maize cob charcoal is very easy to make and leaves few charcoal fines. (no need for expensive briquetting)
  3. They are easy to light and burn very hot with little ash and are perfect for cooking a quick meal.
  4. Using maize cob charcoal means ZERO reliance on tree's and forests, LPG gas or unreliable and expensive electricity supplies for your cooking fuel needs. And with a Cookswell Jiko you can bake, boil, roast and toast all of your favorite foods

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.

As the United States biomass thermal and power industry continues to expand, new reliable technologies offering higher efficiency solutions must be introduced. The newly introduced EOS series biomass gasification boiler is among the most energy efficient of AESI’s high-performance, low-maintenance biomass energy plants. The EOS series provides thermal outputs ranging from 600,000 BTU/hr to 20 million BTU/hr, and can be staged to provide increased capacity.

Designed and built by the leaders in the biomass waste to energy market in Europe, Uniconfort, the EOS series builds upon over 50 years of experience and over 4000 successful installations throughout the world. When asked about the highly efficient EOS series, CEO of Uniconfort Davis Zinetti notes, “we must not forget that greater efficiency is associated with less CO2 production. Choosing EOS, therefore, means making a choice in favor of the environment.”
