PURPOSE: A wear-preventing device capable of preventing the abrasion of an upper/lower pipe of a boiler water pipe of a cooling chamber for coke dry quenching facility by virtue of own weight of red-hot coke is provided which extends the service life of the boiler water pipe and prevents the obstruction of coke discharge. CONSTITUTION: The boiler water pipe of a cooling chamber for coke dry quenching facility comprises: an upper pipe(131) and a lower pipe(132) constructed in parallel in a longitudinal direction; a plurality of connecting pipes(133) constructed in a vertical direction between the space of the upper pipe and lower pipe; and a wear-preventing plate(134) constructed on both side walls of the connecting pipes, wherein a left/right body is rounded on a peripheral face of the lower pipe in the shape corresponding to a peripheral face of the lower pipe, a pair of lower covers(20,20') comprising a left/right flap are constructed in parallel with both side walls of the left/right body. |
