  • Biomass-mixed-firing pulverized coal fired boiler and operation method of the boiler
    Patent number: 9068746
    Abstract: A biomass-mixed-firing pulverized coal fired boiler includes: a furnace for burning biomass fuel together with pulverized coal in a mixed state; a pulverized coal burner for supplying the pulverized coal into the furnace; a biomass burner for supplying the biomass fuel into the furnace; a biomass mill for milling the biomass fuel to be supplied to the biomass burner; a dry clinker processing unit provided below the furnace and including a clinker conveyor for carrying ashes discharged from the furnace at a furnace bottom; and a combustion-air supply unit for supplying combustion air toward the ashes discharged at the furnace bottom on the clinker conveyor, thereby to burn an unburned component of the biomass fuel contained in the ashes discharged at the furnace bottom on the clinker conveyor.
