Abstract
An apparatus for cooling bulk material with a grate flowed through by cooling gas. The apparatus comprises a plurality of planks configured to move forward and back in the direction of conveyance and, between the planks, a sealing device having spatially separate outer and inner sealing elements. The sealing device has between the sealing elements a conveying duct, which runs along the length of the planks and on which a gas supply is configured to produce a gas stream along the length of the conveying duct. Bulk material which has infiltrated through the outer sealing element can be transported away before it can reach and migrate through the inner sealing element. The accompanying sealing effect can considerably reduce the undesirable material through-fall, while enabling the use of low-wearing seals, which provide excellent wear resistance.
