1. 01/01/1980 This guide describes how to construct a transportable charcoal kiln. The kiln is made from sheet metal and can be built in a workshop by local craftsmen with a resaonable skill level. 20 pages, illustrations
  2. 06/01/1980 This guide describes how to operate a transportable charcoal kiln. The kiln is made from sheet metal and can be built by local craftsmen with a workshop which has basic welding, rolling, drilling, and cutting facilities. 18 pages, illustrations, photos
  3. 01/01/1984 Os objetivos do projeto eram: substituto combustível renovável local para combustível importado, uso o recurso de floresta sabiamente, e criam indústria local e emprego. Mais especificamente para a porçăo de carvăo do projeto, nós querida achar as melhores técnicas de produçăo de carvăo em...
  4. 01/01/1980 A réplica é um dos meios mais eficientes de carvăo de qualidade bom produtor. Wood é colocado em um cilindro de aço grande (ou "réplica") . Isto tem um porta firmemente fechada, e alguns meios para deixar piche e supre com gás escape. O cilindro está aquecido do outside. Nenhum ar entra no...
  5. Using earth as a shield against oxygen and to insulate the carbonising wood against excessive loss of heat is the oldest system of carbonization and surely goes back to the dawn of history. Even today it is perhaps used to make more charcoal than any other method. It is, therefore, worthy of...
  6. The earliest industrial, use of charcoal, more than four thousand years ago, was as a reductant for iron smelting to change iron oxide into metallic iron. But charcoal was already well known as a high grade smokeless fuel for cooking and domestic heating. With the emergence of industrial society...
  7. The Tropical Products Institute (TPI), a scientific unit of the Overseas Development Administration, has gained considerable experience in operating transportable metal kilns of various designs both in the U.K. and in many developing countries. The Institute has evolved a kiln design which is...
  8. The carbonization stage may be decisive in charcoal production even though it is not the most expensive one. Unless it is carried out as efficiently as possible, it puts the whole operation of charcoal production at risk since low yields in carbonisation reflect back through the whole chain of...
  9. Properly constructed and operated brick kilns are without doubt one of the most effective methods of charcoal production. They have proved themselves over decades of use to be low in capital cost, moderate in labour requirements and capable of giving surprisingly good yields of quality charcoal...
  10. The alternative to digging a pit is to stack the wood above the ground and cover the stack with earth. This method is also very old and is widely used in many countries. One finds many variations of the basic method. Studies have been made in some countries to optimise the design. The Swedish...
