Title:
SOLID FUEL BURNER
Document Type and Number:
WIPO Patent Application WO/2020/153404
Kind Code:
A1
Abstract:
The present invention is provided with: a venturi (33) that constricts a channel (24) for a mixed fluid in a fuel nozzle (21) toward the center in a cross-section of the channel; a fuel enricher (34) that imparts a velocity component in a direction leading away from the center of the fuel nozzle (21) to the mixed fluid; and a channel partition member (36) that partitions the channel of the fuel nozzle (21) into an inner side and an outer side. Even if solid fuel particles produced by pulverizing a biomass fuel are used, the degree of enrichment of the fuel can be ensured by using a plurality of blades (34c, 34d) which impart swirl to the mixed fluid and which are not secured to the inner side of the fuel nozzle (21) along the entire surface thereof.
