Abstract:
A two-layer sintering process for the thermal transformation of organic substances and of materials containing organic substances wherein a first layer is ignited in a combustion area and thereafter, a second layer is charged into said area and thermally treated, characterized in that the second layer (8) contains organic substances and is charged at a maximum layer thickness of 20% of the first layer and that the thermal treatment of the second layer (8) is started when the temperature of the combustion zone (6) of the first layer ensures the combustion of at least 70% of the organic substances coming from the second layer and entering the combustion zone (6) of the first layer, following the pressure difference, and the area above the combustion zone (6) of the first layer has a temperature which prevents the organic substances coming from the second layer (8) and entering the first layer from condensing.
