Obiettivo In smelting reduction processes, oxygen and coal consumption is strongly dependent on the gas chemical energy utilization, i.e. on the postcombustion ratio. The objective of this project is to develop a combined postcombustion model for improving operation and engineering of smelting reduction processes. Three existing mathematical models are to be improved. In two of these models, kinetic aspects of postcombustion are included; one model refers to the free space zone and the other one to the slag zone. In this latter model, foaming phenomena are also considered. The third model - dynamic slag-droplet model of convertor - will first be modified to take into account postcombustion, and then to incorporate elements of the first two models. Single improved models are validated at different scales from laboratory, to pilot plant and to industrial scale, and then the combined model is validated on pilot and industrial plant and finally, implemented for on-line validation on a pilot plant for process management.
