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.
A nozzle distributor base operable for distributing a gas which is laden with fine solids particles, and including a plurality of nozzles, at least one movable cleaning device arranged on the distributor base and operable to reduce the formation of deposits on the distributor base and on the nozzles of the nozzle distributor base, or to at least partially remove deposits which have already formed, the cleaning device including cleaning elements operable to clean the distributor base and its nozzles by a direct mechanical, striking action on at least one of the distributor base and the nozzles.
A method for reducing the formation of deposits and/or for at least partially removing deposits on a distributor base and on nozzles of the nozzle distributor base, including at least one movable cleaning device operable on the distributor base, the method comprising, while the distributor base is operating during passing particle laden gas through the nozzles, cleaning the distributor base by a direct, mechanical or a striking action of the cleaning device on the distributor base or the nozzles or on the corresponding deposits at the nozzles.
