Summary:

The article presents a technological method of increasing the flow rate of pulverized coal by imputing the FeO arrival with the components of the charge due to increasing the FeO content in the agglomerate and loading briquettes of the grade БЖС-Д. The influence of the proposed compensating resource in the actual operating conditions of the blast-furnace shop of PJSC «Dneprovsky Iron & Steel Integrated Works» is shown.

Keywords:

Pulverized coal, agglomerate, FeO content in the agglomerate, briquettes, blast furnace, regression analysis.
