Abstract
a. L'invention concerne un procédé permettant d'enrober des particules destinées à des éléments combustibles ou absorbants par pyrolyse de gaz dissociables. b. Le procédé est caractérisé en ce qu'on prévoit un refroidissement de l'injecteur de gaz au moyen d'un autre gaz et refroidit seulement la partie axiale de buse d'injection, qui est d'autre part protégée de la chaleur extérieure par une isolation thermique. c. La durée de fonctionnement de la buse d'injection est augmenté fortement, et l'entretien est facilité
