Abstract
The invention relates to a method and apparatus for cooling fired bulk material in which the height of the material bed on a grate conveyor in a first cooling zone is set by the conveying speed of the grate and by gravity. Thus in a particularly simple way the height of the material bed on the conveyor is adjusted in the transport direction in the first cooling zone which serves for heat recovery.
