Title:
固体燃料バーナ
Document Type and Number:
Japanese Patent JP7413284
Kind Code:
B2
Abstract:
The present invention is provided with a venturi (33) in which a mixed fluid channel (24) in a fuel nozzle (21) narrows in the channel cross section toward the center, a fuel concentrator (34) that applies a velocity component away from the center of the fuel nozzle (21) to the mixed fluid, and a channel separation member (36) that separates the fuel nozzle (21) channel into an internal side and an external side. The effectiveness of concentrating the fuel can be ensured even in cases of using solid fuel particles of pulverized biomass fuel by way of a plurality of blades (34c, 34d) that cause the mixed fluid to swirl and are not entirely fixed to the internal side of the fuel nozzle (21).
