Abstract
A biomass-mixed, pulverized coal-fired burner is provided, 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 fuel jet nozzle that is open midway in the biomass fuel jet nozzle, a secondary air nozzle that surrounds the fuel jet nozzle, and a tertiary air nozzle that surrounds the secondary air nozzle. A pulverized coal component in a fuel stream as a mixture of the pulverized coal fuel stream and the biomass fuel stream is distributed with a higher concentration on an outer circumferential wall side and a biomass fuel component in the fuel stream is distributed inside of the pulverized coal fuel component.
