Abstract
A clinker inlet distribution grate for feeding a conveyor grate with clinker, previously discharged from a kiln onto the clinker inlet distribution grate wherein the clinker inlet distribution grate comprises at least a chute with at least two grate elements being arranged one besides the other providing a chute enables to easily remove clinker agglomerations, so called snowmen if at least a first of said at least two grate elements is static and that at least a second of said at least two grate elements is movable orthogonally to the cross direction of the chute.
Claims18
A clinker inlet distribution grate for cooling clinker being discharged via a clinker inlet from a kiln onto said clinker inlet distribution grate by injecting a cooling gas into the clinker layer, said clinker inlet distribution grate is configured to transport said clinker to a conveyor grate, the clinker inlet distribution grate comprising:
- a chute with rows of grate elements, wherein each row
- comprises grate elements being arranged one besides another, and
- has an up-facing surface configured to support the clinker,
- wherein at least one row comprises at least one static grate element and at least one movable grate element, said at least one movable grate element being movable orthogonally to the longitudinal direction of at least one row.
A method for releasing a clinker pile on a chute, located downstream a kiln and upstream a conveyor grate that is configured to convey and cool the clinker, the method comprising:
- shifting at least one movable grate element of the chute in at least one of forward and backward directions and approximately parallel, within ±25°, to a direction of clinker transport down the chute, said shifting being relative to at least one of grate elements besides said movable grate element.
