A DISTRIBUTOR BOTTOM FOR A REACTOR, THE BASE COMPRISING MULTIPLE OPENINGS WHEREIN THE NEAR-WALL OPENINGS ARE ARRANGED AT A DISTANCE FROM THE WALL TO THEIR CENTERS OF 1 TO 10 TIMESTHE DIAMETER OF SAID OPENINGS

摘要

The invention relates to a distributor base 1, in particular anozzle distributor base, for uniformly introducing process gas,in particular laden with solid particles, possibly to form afluidized bed, into a process chamber 3 which is arranged abovethe distributor base and is formed by reactor walls 4 of areactor for the metallurgical, in particular thermal, treatmentof feedstock, the distributor base having a multiplicity ofopenings. Anear-wall arrangement of openings in thedistributor base allows deposits on reactor walls to beavoided. Special arrangements concern nozzles and guide tubes.
