The aim of this work is to study the blast furnace raceway conditions at typical blast pressures and very high rates of oxygen and coal. The study concentrated in particular on the role of the pressure, which is an important parameter affecting the process in the zone in front of tuyeres as far as the combustion behaviour, the raceway shape and its stability are concerned. For this study an experimental technique on a Centro sviluppo materiali (CSM) pilot apparatus named Raceway Plant has been set up.

The research activity is a part of more general study which also involves British Steel and Hoogovens, having the aim of developing the know-how concerning the blast furnace raceway, which is considered critical for a smooth blast furnace operation. Moreover its importance will increase because of development of a current trend towards lower coke consumption that involves different conditions at the tuyeres due to the massive use of coal injected. .
