Abstract: A solid fuel burner to be inserted into a burner throat bored in a wall portion of a furnace, comprising: a solid fuel nozzle for ejecting mixed fluid of solid fuel and primary air; a secondary air nozzle for ejecting secondary air; a tertiary air nozzle for ejecting tertiary air; a secondary air guide member for guiding a flow of the secondary air outwardly in a radial direction; and one or more tertiary air guide members for guiding a flow of the tertiary air outwardly in the radial direction at a first angle with respect to a central axis (C) of the solid fuel burner, wherein a distal end position (X2) of each of the tertiary air guide members in an axial direction of the solid fuel burner is at a closer side of the furnace than a distal end position (X1) of the secondary air guide member.
