Abstract: In a burner for combustion of a pulverized coal mixture having two kinds of rich and lean concentration, a height of a burner panel is reduced and the overall burner is simplified. A rich/lean separator (10, 20, 30) is provided within a pulverized coal conduit (2) so that a high concentration mixture is formed in an outer peripheral portion and a low concentration mixture is formed in a central portion within a single pulverized coal conduit. Thus, a rich mixture burner and a lean mixture burner which have been conventionally provided separately may be formed into a single burner. A recirculation of air is accelerated by a cutaway slit (20d, 30d) provided in a central portion of the rich/lean separator to thereby make uniform the air flow rate distribution in a pulverized coal nozzle. Also, a duct and an air blow box for the combustion air to be supplied to the pulverized coal flame are not integrally formed to be continuous in the height direction but may be divided into a plurality of discontinuous units. <IMAGE>
