Abstract

Le procédé consiste à former, dans un dispositif de dosage unique (12), un mélange pneumatique comprenant une teneur relativement élevée de matières pulvérulentes dans du gaz de propulsion, à propulser ce mélange à travers une conduite primaire (10) commune jusqu'à une tête de distribution (16) dans laquelle le mélange est scindé en courants secondaires (18) qui sont envoyés respectivement à chacun des points d'injection (22) à travers des con­ duites secondaires et à régler le débit du courant pneumatique dans chacune des conduites secondaires. The method consists in forming, in a device for single dosing (12), a pneumatic mixture comprising a relatively high content of pulverulent matter in propellant gas, propel this mixture to through a common primary pipe (10) to a head distribution (16) in which the mixture is divided into secondary currents (18) which are sent respectively at each of the injection points (22) through cones secondary picks and to adjust the current flow pneumatic in each of the secondary lines.
