More Information
Summary:Provided is a solid fuel burner wherein a high-temperature oxygen remaining area formed on the outer periphery of flame is suppressed so that the final NO x generation can be reduced. A solid fuel burner (20) is used at a burner portion of a solid fuel boiler divided into the burner portion and an additional air charging portion, to perform a low NO x combustion, and charges granular solid fuel and air into a furnace. The solid fuel burner is provided with a fuel burner (21) in which flame is maintained, and a secondary air charging port (30) in which flame is not maintained. The air ratio of the fuel burner (21) is set at 0.85 or more.
