The invention relates to an apparatus and a process for distributing a lumpy bulk material, in particular iron ore which has been at least partially prereduced, onto an extensive surface, in particular onto a fixed bed, this surface extending within a reactor or vessel used in physical or chemical process technology, in particular in a reactor used in a metallurgical plant to produce pig iron or primary steel products, and the lumpy bulk material being charged via at least one charging apparatus, which has at least two, in particular rotationally symmetrical, chutes, which are preferably arranged at the same distance from the vertical longitudinal axis of the reactor. In this arrangement, at least a proportion of the bulk material, in particular after it has been introduced into the chute, before it comes into contact with the extensive surface, is distributed in the radial and/or tangential direction—as seen from above—at a scattering device which is assigned to at least one of the chutes and is preferably in the chute.
A scattering device for use in apparatus for distributing lumpy bulk material over an extensive surface in a reactor or vessel, wherein the scattering device comprises a plurality of chains disposed where the lumpy material is introduced into the vessel for contacting and for scattering the lumpy material being introduced in the vessel, and each having a plurality of scattering nodules thereon spaced at intervals along the chain.
A scattering device for use in apparatus for distributing lumpy bulk material over an extensive surface in a reactor or vessel, wherein the scattering device comprises a chute through which the lumpy material is introduced into the vessel, and the chute having an inner side with a number of projections thereon.
