Grinding and drying as well as pulverized coal injection is today state-of-the-art in Küttner's product portfolio. Over decades improvements and developments have been made for the benefit of our clients. The aim was always to increase the injection rate by reducing the coke rate at the same time. Overall ironmaking cost should be reduced by keeping a predictable and safe blast furnace operation. Now, the engineers of Küttner have developed the next logical step to even more reduce finally the coke rate. Reactive PCI® allows you to replace a part of the necessary transport gas for the pulverized coal by a so-called reactive gas. Reactive, because it is taking part in the reactions with the injected pulverized coal. The mathematical model will be introduced as well as first promising results.
