Abstract

L'invention a pour objet un procédé et un dispositif de pulvérisation d'une matière combustible solide introduite à l'intérieur d'une enceinte au moyen d'un transporteur à vis par une filière débouchant à l'intérieur de l'enceinte et dans laquelle est formé par extrusion un boudin de matière comprimée, celle-ci étant désagrégée par au moins un jet de gaz injecté sous forte pression. The subject of the invention is a method and a device for spraying of solid combustible material introduced to the interior of an enclosure by means of a screw conveyor by a die opening inside the enclosure and in which is formed by extrusion a rod of material compressed, the latter being disintegrated by at least one jet of gas injected under high pressure.

Selon l'invention on injecte le gaz à partir de l'intérieur du transporteur à vis et dans l'axe de chaque filière, chaque jet gazeux ayant une impulsion suffisante pour former sensiblement un cône centré sur l'axe du boudin en s'élargis­ sant à l'intérieur de celui-ci, chaque boudin étant constitué d'un tube creux dont la paroi interne s'effrite et prend la forme du jet en libérant des particules qui sont aspirées dans le jet et introduites avec lui dans l'enceinte. According to the invention the gas is injected from the inside of the screw conveyor and in the axis of each die, each gas jet having enough momentum to form substantially a cone centered on the axis of the rod in widening health inside of it, each tube being made up a hollow tube whose inner wall crumbles and takes the jet form by releasing particles which are sucked into the jet and introduced with it into the enclosure.

L'invention s'applique spécialement à l'alimentation d'un réacteur de gazéification. The invention applies especially to food a gasification reactor.
