Abstract
A processing gas is supplied to the atomizing zone around an atomizing device arranged centrally in an atomizing chamber through a conical guide duct communicating with a horizontal spiral supply duct through an annular mouth. A uniform gas distribution with respect to flow direction and velocity is obtained by means of guide vanes arranged with a small angular spacing in the mouth and comprising two succeeding vane sets, in which the vanes of one set are shaped to deflect the tangential gas stream in the spiral duct to a flow direction, for which the radial velocity component considerably exceeds the tangential component, whereas each vane of the other set positioned at the opening of the mouth towards the conical guide duct projects into the space between neighboring vanes of the first set and extends substantially parallel to tangential planes to said vanes at their internal edges.
