SOLID FUEL BURNER

摘要

The present invention provides a solid fuel burner which prevents the generation of an insufficient oxygen region by dispersing a solid fuel concentrated on the lower part of an inner wall of a solid fuel burner nozzle, thereby preventing reduction of flammability at an outlet of the burner. A dispersion support member (11) as a member of supporting, in a solid fuel nozzle (3), a solid fuel concentrator (10) in the solid fuel nozzle (1) is obtained by integrating a curved-plate-like base part (11b) in accordance to the inner wall of the solid fuel nozzle further downstream than an installation part of the solid fuel concentrator (10) with multiple support parts (11a) formed to support a lower surface of the solid fuel concentrator (10) from the lower part of the inner wall of the solid fuel nozzle (3) while the plate-shaped members (11a) in parallel to a solid fuel passage are radially-arranged with respect to a central shaft of the solid fuel nozzle (1).
