Abstract (en)

Disclosed herein is a nozzle tip of a pulverized coal burner, which is capable of preventing the abrasion and separation of flame stabilizers due to the flow of pulverized coal. The nozzle tip includes an inner tubular body (100) having a first passage (120) in which pulverized coal introduced into the inner tubular body (100) flows, an outer tubular body (200) installed outside the inner tubular body (100) while being spaced apart therefrom, and at least one guide plate (300) installed to partition the first passage (120). The nozzle tip further comprises: a plurality of flame stabilizers (400) arranged in a row at the upper and/or lower side in the inner tubular body (100), wherein each of the flame stabilizers (400) has an inclined surface (420, 1420) formed on a side thereof facing a direction in which the pulverized coal flows in the first passage (120), the inclined surface (420, 1420) being inclined toward a central portion of the inner tubular body (100).
