Abstract
A slide plate 10 for a slide 1 for Geldart group C materials with a longitudinal axis 2, an up-facing surface 11 for supporting the Geldart group C material, a lower surface 13, a front-side surface 12 and a rear-side surface 14 may have a significantly reduced slope if the slide plate 10 is made of a ceramic refractory, wherein the slide plate has a number of through holes 20 providing a fluid communication between fluid inlets 23 in the lower surface 13 and fluid outlets 21 in the up-facing surface 11.

-15. (canceled)
A slide plate dimensioned to be inserted into a slide of a conveyor configured to convey Geldart group C materials, wherein:
- the slide plate has a longitudinal axis, an up-facing surface configured to support the Geldart group C material, a downward-facing surface, a front-end surface, and a rear-end surface,
- the slide plate is made of a ceramic refractory,
- the ceramic refractory has through holes configured to provide fluid communication between fluid inlets in the lower surface and fluid outlets in the up-facing surface,
- and
- a fluid outlet of at least one of the through holes is closer to the front-end side surface than a fluid inlet of said at least one of the through holes.
The slide plate of claim 1, configured to have a pressure gradient Δp↑ between the up-facing surface and the downward-facing surface smaller than or equal 2 kPa.
The slide plate of claim 1, wherein the down-facing surface has at least one recess and/or protrusion providing a first stop surface that faces towards the front-end surface and/or a second stop surface that faces towards the rear-end surface, wherein said first stop surface and/or said second stop surface is dimensioned to limit a movement in a direction parallel to the longitudinal axis.
A conveyor slide configured to convey hot Geldart group C materials, wherein the slide comprises at least one slide plate according to claim 1.
The slide of claim 6, wherein the at least one slide plate includes multiple slide plates, the up-facing surface of the at least one slide plate has a corresponding slope smaller than 25° relative to the horizon, and/or the most upstream of the multiple slide plates has a corresponding slope that is greater than that of at least one downstream slide plate of the multiple slide plates.
A method for conveying a Geldart group C material, the method comprising at least:
- depositing the Geldart group C material on the up-facing surface of the slide of claim 6, and
- providing a gas flow of less than half a cubic meter of gas under normal conditions per second and per area of a slide surface through through-holes to an up-facing surface of the slide.
