Abstract

This project is an extension of an earlier project undertaken by British Steel plc, which developed a model to investigate coke combustion in the blast furnaces used in steel production. The focus of this project was coal and oil combustion, and its aim was to find ways of increasing the rate of coal injection and minimizing the amount of coke produced. A mathematical model of blast furnace conditions has been developed which simulates the characteristics of the blowpipe, tuyere or injection nozzle, and raceway in a blast furnace, and can be used to assess the movement of coal particles in a gas stream, coal devolatilization and coal char combustion. The model is divided into two parts. The first of these is the trajectory model, which simulates blowpipe and tuyere conditions at the interface between the injection point and the tip of the tuyere, and the second, the raceway model, calculates the conditions at that point. This model can be applied to both coal and oil injection, and can assist in defining the optimum combination of the variables involved in fuel injection and combustion.
