Abstract

Provided is a pulverized coal/biomass mixed combustion burner capable of combusting large volumes of biomass fuel as an auxiliary fuel and capable of combusting only pulverized coal if there is insufficient biomass fuel. The pulverized coal/biomass mixed combustion burner (1) comprises: a biomass fuel jet nozzle (20) that follows the axis of the pulverized coal/biomass mixed combustion burner (1); a fuel jet nozzle (30) that causes the biomass fuel jet nozzle to open partway along the tube; a secondary air nozzle (40) that surrounds the fuel jet nozzle; and a tertiary air nozzle (50) that surrounds the secondary air jet nozzle. The pulverized coal/biomass mixed combustion burner is configured so as to: thickly distribute the pulverized coal component of a mixed flow comprising the pulverized coal fuel flow and the biomass fuel flow to the outer perimeter wall side; distribute the biomass component to the inside of the pulverized coal component; generate a pulverized coal fuel flame having good ignition and flame stability inside a furnace; and jet the biomass fuel flow to the inside of this flame.
