Controlling circumferential variability in a blast furnace may include generating a predictive model that sets up a relationship between a standard deviation of a selected state variable, state variables and one or more control variables in blast furnace operation for predicting the standard deviation. A number of circumferential sections of the blast furnace is defined, and the predictive model associated with the selected state variable for each of the circumferential sections is trained based on process data of the blast furnace. A plurality trained predictive models is generated associated with different circumferential sections and different selected state variables. One or more future control variable set points that minimize a sum of the plurality of predictive models, is determined. One or more future control variable set points is transmitted to a control system to control the blast furnace operation.

A process and a plant for cleaning furnace gas includes utilizing one or more sensors to continuously monitor one or more parameters indicative for an expected temperature peak in the blast furnace gas flow. The gas flow is then passed through a conditioning tower. In case the measured parameter exceeds a predefined limit value, a coolant, such as water, is sprayed into the blast furnace gas flow in the conditioning tower. Subsequently the flow of blast furnace gas passes one or more filter stations.
