Abstract (en)

In a pyrolysis installation with a rotary pyrolysis furnace (1), the furnace (1) is connected by a sealed connection (10) to an upstream solids preheating arrangement (2) having at least two zones (2a,b) in which the solids are preheated to different temps., and a gas extraction device (12), into which pyrolysis gas passes after passage through at least one of the zones (2a,b). Also claimed is a solids pyrolysis process involving preheating the solids to different temps. and self-cleaning of the pyrolysis gas by percolation relative to the preheating stage. <IMAGE>
