Title:
微粉炭バイオマス混焼バーナ
Document Type and Number:
Japanese Patent JP5897363
Kind Code:
B2
Abstract:
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 1 includes: a biomass fuel jet nozzle 20 that extends axially along the biomass-mixed, pulverized coal-fired burner 1; a pulverized coal fuel jet nozzle 30 that surrounds the biomass fuel jet nozzle 20; a secondary air nozzle 40 that surrounds the pulverized coal fuel jet nozzle 30; and a tertiary air nozzle 50 that surrounds the secondary air nozzle 40. 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.
