Abstract

Un procédé d'élimination de dépôts de cendres de surfaces consiste à produire des impulsions d'ondes de chocs au moyen d'explosions de charge de poudre, et à soumettre à ces impulsions les surfaces présentant des dépôts de cendres. Un dispositif de mise en ÷uvre du procédé comprend une zone (9), permettant l'explosion d'un vecteur d'énergie, reliée à une zone (11) permettant de former l'onde de choc et constituée par un tube (14) dont une extrémité (16) est ouverte. La zone (9) où se produit l'explosion du vecteur d'énergie se compose d'une chambre de combustion (13) dont la cavité destinée à la charge de poudre (10) est reliée par un canal (17) à la cavité (28) du tube (14), laquelle est reliée mécaniquement audit tube (14). Du côté de la chambre destinée à la charge de poudre (10) de ladite chambre de combustion (13) se trouve un système (12) d'amorçage de l'explosion.
