Coke properties in the bosh and raceway regions of the blast furnace*
Propriétés du coke dans les étalages et dans les zones tourbillonnaires du haut fourneau
Changes in coke properties in the bosh and raceway regions of the blast furnace are controlled by the thermochemical and mechanical action of the blast.
British Steel has carried out laboratory work using high temperature furnaces and a half-scale single tuyere rig which can simulate the raceway. These investigations have been supported on-plant by bosh coke sampling exercises and more recently the use of a through tuyere coring drill. It has provided a section of the coke bed structure at tuyere level from operating furnaces.
The combined findings of both the laboratory and plant investigations in terms of coke properties and tuyere level coke bed structures, and their relationship to blast furnace processes are shown.
