Patent ID: 8221674

Claim:
A reactor for thermal metallurgical treatment of feedstock, the reactor comprising a distributor base, a process chamber being arranged above the distributor base and including reactor walls of the reactor, the distributor base being operable for uniformly introducing process gas which is laden with solid particles to form a fluidized bed, in the process chamber, wherein there is a multiplicity of openings in the distributor base, including near-wall openings arranged at a distance from the reactor walls such that a distance of the center axis of each near-wall opening from the portion of the reactor walls nearest to each near-wall opening is at most 1 to 10 times the diameter of the near-wall opening, or the ratio of the distance between the center axis of each near-wall opening and the center axis of the distributor base in relation to the radius of the distributor base is 0.9-1, and wherein at least one of the near-wall openings forms an angle of greater than 0° and less than or equal to 15° or less than 0° and greater than or equal to −15° with a normal to the distributor base to introduce a targeted flow that is inclined with respect to a main direction of flow of the process gas.
