摘要:
The invention relates to a device for unloading bulk material, which comprises a plurality of elongate retaining elements (12, 14) extending parallel to one another in a longitudinal direction (X), forming a support surface (16) for the material, intended for being in contact with the material, in which the retaining elements (12, 14) are arranged next to one another in a transverse direction (Y) perpendicular to the longitudinal direction (X) while also defining interstices therebetween, intended for allowing the flow by gravity of at least one portion of the material, in which at least two retaining elements (12, 14) are translatably movable relative to one another in the longitudinal direction (X). The invention can be used in a storage silo or in a biomass roasting column.
摘要:
Solid fuel combustion equipment in the form of a grate assembly comprises longitudinally extending support elements 6 on which are mounted laterally orientated grate bars (10). The support elements (6) are pivotable about their horizontal axes and are provided with sealing means (14) at their adjacent margins to effect a seal to prevent in use passage of air when the elements (6) are horizontally aligned. De-ashing of the grate assembly in use is achieved by tipping the support elements (6), whereupon ash falls to a receiving are (11) whence it is removed.
