Biomass-mixed, pulverized coal-fired burner and fuel combustion method
A biomass-mixed, pulverized coal-fired burner is provided. The biomass-mixed, pulverized coal-fired burner is capable of burning biomass fuel as auxiliary fuel in large quantities and burning only pulverized coal when the biomass fuel is not sufficiently available. The biomass-mixed, pulverized coal-fired burner includes: a biomass fuel jet nozzle that extends axially along the biomass-mixed, pulverized coal-fired burner; a pulverized coal fuel jet nozzle that surrounds the biomass fuel jet nozzle; a secondary air nozzle that surrounds the pulverized coal fuel jet nozzle; and a tertiary air nozzle that surrounds the secondary air nozzle. A biomass fuel stream is jetted into an inside of a pulverized coal fuel flame formed in a furnace, the flame offering favorable ignition and flame holding performance.
