Abstract

La présente invention concerne un courant de traitement gazeux que l'on peut diriger dans un espace de travail ou vers une pièce à travailler et qui est formé en introduisant à combustible, un oxydant et un matériau de traitement dans une buse thermique. Le combustible brûle dans la buse thermique avec l'oxydant et avec les composants combustibles, le cas échéant, du matériau de traitement, pour former le courant de traitement gazeux qui est émis à partir de la buse thermique à une vitesse et une quantité de mouvement élevées et contrôlables.
