ABSTRACT:
A method is suggested for the reduction of finely-divided iron oxide in a fluidized bed, with the air of reducing gases formed by partial combustion in the bed of finely-divided carbonaceous material by gas containing molecular oxygen, which is supplied through nozzles (4). The exterior surface of the nozzles is cooled to a temperature lower than 200.degree. C below the melting point of the reduced metal. In this way the particles of the reduced iron are prevented from adhering to the nozzles.
