To reduce running cost, and to improve an operation rate by applying a structure operable without using a concentration adjusting ring and affected by pulverized coal, and free from abrasion.
In this pulverized coal burner 2 which includes a cylindrical pulverized coal nozzle 8, and a cylindrical tertiary air nozzle 9 disposed in the pulverized coal nozzle coaxially therewith, and in which a pulverized coal/primary air mixture flow 15 is supplied to a flow channel 22 formed between the pulverized coal nozzle and the tertiary air nozzle, and jetted from a tip of the nozzle to be burned, jetting ports 24 are pierced at a tip of the tertiary air nozzle at prescribed pitches in the circumferential direction, so that air is jetted from the jetting ports to form a separation area to the mixture flow.
