Clinker Inlet Distribution System (KIDS)

IKN KIDSThe IKN KlDS distributes the clinker evenly across the grate width and conditions the clinker bed to improve its air permeability. The inclined slots of the Coanda Nozzles generate horizontal air jets which pressurize the bottom layer of the clinker bed. The air jets turn vertical upon striking against clinker particles and uniformly penetrate the clinker bed. Fines are sifted out of the voids between larger particles and accumulate at the surface where they gently fluidize.
The bed voidage in each layer within the clinker bed is maximized. The main features of the IKN KIDS are:

  • Uniform clinker distribution across the grate width.
  • Transport of the fines to the bed surface.
  • Rapid cooling of the lower clinker bed.
  • Lower clinker outlet temperature.
  • IKN KIDSLess maintenance of the grate.
  • Improved recuperation.
  • Power savings due to  reduction of cooling air.
  • Stabilized kiln/cooler operation.
