摘要：Method for operating a shaft furnace, whereby an upper section of the shaftfurnace is charged with raw materials which due to gravity descend inside the furnacewhile the atmosphere prevailing within the shaft furnace causes part of the raw materialsto melt and/or to be reduced, and in a lower section of the shaft furnace a process gas isinjected so as to at least partly modify the atmosphere prevailing in the shaft furnace.The pressure and/or volume flow of the injected process gas is dynamically modulatedwithin a time span of 40 s. Also, a shaft furnace operable by said method, thus achievingimproved through-gassing.
