Abstract
A nozzle distributor base for distributing a gas which is laden with fine solids particles, preferably for use in a fluidized-bed unit, in particular for the reduction of metal oxide-containing solids particles. At least one movable cleaning device on the distributor base reduces the formation of deposits on the distributor base or the nozzles thereof or at least partially removes deposits which have already formed. Elements in the distributor base, like chains, ropes or movable rods, clean the distributor base by direct mechanical striking action on the distributor base and/or the nozzles of the nozzle distributor base. A method for reducing the formation of deposits and/or for at least partially removing deposits on a distributor base uses the striking action.
