The automatic continuous carbonization Lambiotte retort, type CISR, forms the heart of the installation which comprises, first, the preparation of wood and last, the processing and packing of the charcoal.
The lambiotte process is characterized by the fact that only the pyroligneous vapours are burnt, and not the wood nor the charcoal, thus giving an output of charcoal twice to five time as high.
The automatic operation of the installation entails a very large reduction in personnel required and, moreover, the work place is healthy, and more pleasant, and the work is made simple and easy. The "cooled"gas cooling water is recycled and the excess pyroligneous vapours are burnt out in a flare stack to ensure environmental protection. The gases can also feed a burner.

In the Lambiotte process, the charcoal is cooled in the carbonization retort by "cooled" gases, and is discharged at ambient temperature.
It is seen to be perfectly pure and highly homogeneous, of an exceptional quality, with a very high carbon content.
The CISR retort is fully heat-insulated and the absence of corrosive condensation gives the installation a very long life.

Production data :

Annual charcoal production: 2,000 tons or 6,000 tons. Charcoal, Lambiotte process : fixed carbon : 85 to 90% water content: 3 to 4% volatile matters: max 12% Available pyroligneous vapours: equivalent to 109 calories/hour, based on wood with 25% maximum moisture content on total weight.
