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.
Claims20
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 beside 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 a longitudinal direction of the 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 a row, of grate elements, 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 located beside said movable grate element in said row.
A clinker inlet distribution grate for cooling clinker, that is 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 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 beside another, and
- has an up-facing surface configured to support the clinker,
- wherein at least one row, from said rows of the grate elements, comprises at least one static grate element and at least one movable grate element,
- wherein said at least one movable grate element is movable orthogonally to the longitudinal direction of at least one row of the grate elements,
- wherein the at least one movable grate element is supported by at least one guide rail, which is attached to or integrated in the at least one static grate element.
A clinker inlet distribution grate for cooling clinker, that is 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 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 beside another, and
- has an up-facing surface configured to support the clinker,
- wherein at least one row, from said rows of the grate elements, comprises at least one static grate element and at least one movable grate element,
- wherein said at least one movable grate element is movable orthogonally to the longitudinal direction of at least one row of the grate elements,
- and further comprising
- a cross beam configured to support the at least one static element, and
- wherein the at least one static grate element comprises at least one of (i) a carrier, wherein such carrier supports at least one of a grate plate with an up-facing surface for supporting clinker, and (ii) a support adapter configured to attach the at least one static grate element to a cross beam.
