Beschreibung
Zusammenfassung:	The invention relates to thermochemical treatment equipment (100) which includes: a reaction chamber (140); at least one gas inlet (104); and a gas preheating chamber (110) located between the gas inlet (104) and the reaction chamber (140). The preheating chamber (110) includes a plurality of perforated distribution plates (111-114) that are kept spaced apart, above one another. The preheating chamber (110) also includes, between at least the distribution plates facing one another, a plurality of walls (1110, 1120, 1130) defining gas flow paths between said plates (111-114). Une installation de traitement thermochimique (100) comprend une chambre de réaction (140), au moins une entrée de gaz (104), une chambre de préchauffage de gaz (110) située entre l'entrée de gaz (104) et la chambre de réaction (140). La chambre de préchauffage (110) comprend plusieurs plateaux de distribution perforés (111-114) maintenus de manière espacée les uns au-dessus des autres. La chambre de préchauffage (110) comprend en outre, entre au moins les plateaux de distribution en vis-à-vis, une pluralité de parois (1110, 1120, 1130) définissant entre lesdits plateaux (111-114) des chemins de circulation pour un flux gazeux.
