バイオマス燃料用燃焼炉及びボイラシステム並びにバイオマス燃料の燃焼方法

Japanese Patent JP7346008

B2

To provide a biomass fuel combustion furnace capable of effectively burning biomass fuel obtained by mixing waste oil or oil- derived waste fluid and plant-based biomass, and a boiler system.SOLUTION: A biomass fuel combustion furnace 1 includes: a first combustion section 2 performing primary combustion by inputting and igniting biomass fuel; a second combustion section 3 performing secondary combustion; and a third combustion section 4 performing tertiary combustion. The first combustion section 2 includes: a truncated-cone-shaped first combustion chamber 8 disposed so that a central axis thereof is inclined to a horizontal direction; a fuel input pipe 5 for inputting biomass fuel; a burner 6 igniting the biomass fuel; and a first combustion air supply port 9 for supplying first combustion air to the first combustion chamber 8. The second combustion section 3 includes a cylindrical second combustion chamber 17 disposed so that a central axis thereof is inclined to the horizontal direction and rotating about the central axis. Air that has passed through an outer peripheral side of the first combustion section 2 is blown out from a second combustion air supply port 12 to form a turning flow of second combustion air in the second combustion chamber 17.SELECTED DRAWING: Figure 1
