摘要:
In a process for injecting fine-grain brown coal or lignite into a blast furnace through tuyere arches thereof, the initial speed at which coal dust, after leaving the supply conduit, moves towards the center of the blast furnace hearth is substantially lower than the speed at which the hot blast is blown into the furnace.
