Abstract

A solids distributor for injection plants includes a collecting chamber having a plurality of lance lines leading away from the chamber. The chamber has a supply connection for a solid to be distributed and is surrounded by a common wall in which a plurality of ports is formed. The lance lines are connected to the ports, and an annular gap is formed in front of the ports and along the common wall. A pressure vessel is arranged geodetically above the collecting chamber, the lower part of the pressure vessel being designed as a bunker, having an outlet providing a direct and continuous junction to the supply connection and an upper part designed as a gas space. The collecting chamber may include a central displacement body which forms the annular gap with the common wall and which may be an upwardly tapering cone which projects out of the collecting chamber.
