A new combined post-combustion model (CPM) for smelting reduction processes, including two components, "a kinetic section" for the region in the presence of foaming slag and a "CFD (computation fluid dynamic) section" in the free space, was developed.

This research work was especially devoted to the CleanSMelt(registered) process (formerly the cyclone converter furnace, CCF) in which post-combustion is carried out both in a foamy slag (smelter) and in a free space (smelter and cyclone).

A new detailed mathematical description of flame behaviour and of heat transfer from the post-combustion gas to the foamy slag in different zones was written. Such a new detailed description allow simulations of smelting reduction processes, and calculations for a 170 tonne reactor and the CleanSMelt(registered) process on CleanSMelt-PDU (pilot demonstration unit) were made. de.
