Summary:To improve ignitability in a solid fuel burner using solid fuel, which is relatively difficult to ignite, as fuel.SOLUTION: A solid fuel burner comprises a first flow path through which solid fuel and primary air carrying the solid fuel can flow, and a second flow path that is formed on the outside of the first flow path and allows secondary air to flow from an air box. The solid fuel burner is configured to mix at least a part of the solid fuel into the secondary air on the upstream side with respect to the downstream end of the solid fuel burner.SELECTED DRAWING: Figure 3 【課題】比較的着火し難い固体燃料を燃料として用いる固体燃料バーナにおいて着火性を向上することを目的とする。【解決手段】一実施形態に係る固体燃料バーナは、固体燃料と固体燃料を搬送する１次空気とが流通可能な第１流路と、第１流路の外側に形成されていて、風箱からの２次空気が流通可能な第２流路と、を備える固体燃料バーナである。一実施形態に係る固体燃料バーナは、固体燃料バーナの下流端よりも上流側で２次空気に固体燃料の少なくとも一部を混入させるように構成されている。【選択図】図３
