Abstract

A grate bar (1) includes an upper wall portion (2) which extends in a first direction (D), a front wall portion (3) which extends downward from a distal end of the upper wall portion (2), a channel (S) which is provided on a back side of the upper wall portion (2), and a partition wall (8) which vertically divides the channel (S) and includes a partition wall main body (9) of which a main surface faces the upper wall portion (2) and a plurality of cooling holes (10) which are formed in the partition wall main body (9) and eject a cooling medium toward a back surface of the upper wall portion (2) to cool the upper wall portion (2) by impingement.
