Zusammenfassung |

[EN] Method for operating a shaft furnace, whereby an upper section of the shaft furnace is charged with raw materials which due to gravity descend inside the shaft furnace while the atmosphere prevailing within the shaft furnace causes part of the raw materials to melt and/or to be reduced, and in a lower section of the shaft furnace a process gas is injected so as to at least partly modify the atmosphere prevailing in the shaft furnace, characterized in that the injection of the process gas is dynamically modulated in a manner whereby in the modulation the process variables, pressure p and/or volume flow {dot over (V)}, are varied at least intermittently within a time span of <=5 s and most desirably <=1 s. |
