The raceway is an important region of the blast-furance process, but the hostile conditions make the study of the raceway difficult. This project has been concerned with the development of a mathematical model to aid understanding of the raceway. The mathematical model has been developed using information from several sources: a literature review, experimental studies utilizing a physical model and a coke combustion rig. The physical model studies provided information on raceway size, particle motion, pressure distribution and the effect of fine material and liquid. The coke combustion studies were used to provide data on gas analysis and the shape of an actual raceway. The mathematical model which calculates gas and solid flow patterns, temperatures, gas analysis, pressure and voidage, has been used to predict the effect of selective changes in tuyere conditions. Data for an operating blast furance have also been examined using the model. The mathematical model has also been used to simulate the behaviour of an injectant in a simplified manner, but it is realized that this aspect is far more complicated.
