  • Sliding grate for a burnt-material-cooling unit, and grating plate therefor
    Patent number: 5882189
    Abstract: Described is a grating plate for a sliding grating for a burned-material cooling unit, the grating plate having, in the surface which holds the materials, a recess (13) in which cooling-air outlets (10) are located and, below the recess, a cooling-air feed space (17). The depth of the recess (13) increases from back to front. The cross-section of the cooling-air feed space (17) decreases correspondingly from back to front in accordance with the change in the cooling-air flow through the space.

  • Grate cooler for combustion material and process for its operation
    Patent number: 5775891
    Abstract: In a grate cooler, the unstable state which is attributable to an unusually strong accumulation of the combustion material is prevented by the fact that the waste air from the cooler, which is to be fed as secondary air to the kiln, is injected with water. This is expediently carried out in the inlet region of the cooler in dependence upon the temperature and/or the pressure of the secondary air in the kiln hood.
