Abstract: 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.
