A distributor bottom, particularly a nozzle-type distributor bottom, for steadily introducing process gas, especially process gas loaded with solid particles, into a process chamber, optionally to create a fluidized bed. The process chamber is disposed above the distributor bottom and is formed by walls of a reactor used for metallurgically, particularly thermally, treating feedstock. The distributor bottom is provided with a plurality of holes. Holes are arranged near the walls to prevent substances from attaching to the reactor walls. Special arrangements relate to nozzles and ducts.
