Objective

The functioning of the raceway presently appears as the limiting factor for the increase of the coal injection rate at the blast furnace. In order to further reduce the coke rate by 15 to 20kg/thm with reference to the best results presently obtained in Europe, this project aims at investigating the impact of the coal injection on the raceway behaviour, and on the corresponding gas distribution within the furnace.

With this objective, new measuring techniques will be developed and/or implemented in order to measure the raceway characteristics on one side, and to enable the control of the injection condition per tuyere on the other side. These techniques will be applied on actual blast furnaces for the examination of the raceway behaviour under high PCI operation.

They will also be used for the investigation of the raceway functioning on physical models and at pilot scale under coal (and other reducing agents) injection conditions. The obtained results will be implemented in a mathematical model of the heat exchanges in the raceway.
