Abstract
According to a process for injecting metal-oxide-containing fine particles into a reducing gas, a central material stream formed by the fine particles and a carrier gas is introduced into the reducing gas and at least one gas stream formed by a secondary gas is directed against the material stream to ensure an optimum contact of the fine particles with the reducing gas, the gas stream atomizing the material stream and the fine particles being evenly distributed within the reducing gas.
