Abstract

PURPOSE: To obtain a pulverized-coal burner having a smaller NOX generation amount by arranging the first and second pulverized-coal compartments each having a specifically set relationship between the sum of primary and secondary air quantities and an auxiliary air compartment so as to be close to each other.
CONSTITUTION: The coal from a coal storage bin 1 is pulverized in a pulverizer 2 and fed to a distributor 11 through a feed pipe 4 by the primary air from a blower 3. The outlet side of said distributor 11 which has a larger proportion of the pulverized coal is connected through a feed pipe 12 to a pulverized-coal injection nozzle 14, while the outlet side of the distributor 11 having a smaller proportion of the pulverized coal is connected through a feed pipe 22 to a pulverized-coal injection nozzle 24. Said nozzles 14 and 24, together with secondary air injection nozzles 17 and 27 provided around respective nozzles 14 and 24 and connected to the secondary air blower 7 through a feed pipe 15, constitute the first and second compartments respectively. In addition, an auxiliary air compartment including an auxiliary air injection nozzle 18 is arranged so as to be adjacent to the first compartment to obtain a desired pulverized-coal burner.
