Estimating the term…
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.
A process for injecting metal-oxide-bearing fine particles into a reducing gas stream conveyed by a reducing gas line, characterized in that a central material stream formed by the fine particles and a carrier gas is introduced into the reducing gas stream and the reducing gas flows toward the material stream, the material stream being oriented in a direction opposite to the direction of flow of the reducing gas, and at least one gas stream formed by a secondary gas is directed against the material stream, with the gas stream dispersing the material stream and the fine particles being evenly distributed within the reducing gas stream.
