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 Die Objektive des Projektes waren zu: Ersatz örtlicher erneuerbarer Brennstoff für importierten Brennstoff, Verwendung das Wald-Mittel weise, und schaffen örtliche Industrie und Anstellung. Ausdrücklicher für den Kohle-Teil des Projektes, wir wollte die besten Kohle-Produktion-Techniken in...
  4. 01.01.1980 Die schlagfertige Erwiderung ist ein von den tüchtigsten Mitteln vom Produzieren von guter Qualität Kohle. Holz wird in einen großen Stahl-Zylinder gesetzt (oder " schlagfertige Erwiderung ") . This hat ein eng geschlossene Tür, und einige Mittel, Teer und Gase escape. Der Zylinder zu lassen wird...
  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...
