    • A pulverized coal combustion burner has a circumferential distribution of pulverized coal density at an outlet portion of a pulverized coal nozzle made uniform, and a complete NO.sub.x decrease is attained. An oil gun (01) for stabilizing combustion is provided at a center portion. An annular sectional oil primary air flow path (02) surrounds the oil gun (01), and an annular sectional pulverized coal and primary air mixture flow path (14) surrounds the oil primary air flow path (02). Around the mixture flow path (14) is an annular sectional secondary air flow path (15), and an annular sectional tertiary air flow path (16) surrounds the secondary air flow path (15). A pulverized coal supply pipe is connected in the tangential direction to the mixture flow path (14). Further, an entering angle control (28) of the mixture is provided within the pulverized coal supply pipe (11). Within the mixture flow path (14), a pulverized coal density dividing cylinder (25) is provided.
    • 粉煤燃烧器在粉煤喷嘴出口处的粉煤密度的周向分布均匀,达到完全的NOx减少。 在中央部设置用于稳定燃烧的油枪(01)。 环形分段油一次空气流动路径(02)围绕油枪(01),并且环形截面粉煤和一次空气混合物流动路径(14)围绕油一次空气流动路径(02)。 在混合物流动路径(14)周围是环形截面的二次空气流动路径(15),并且环形分段三次空气流动路径(16)围绕二次空气流动路径(15)。 粉煤供给管在与混合流路(14)的切线方向连接。 此外,在粉煤供给管(11)内设置混合物的进入角度控制(28)。 在混合物流动路径(14)内,设置有粉煤密度分配缸(25)。
