Title:
燃焼バーナ及びボイラ
Document Type and Number:
Japanese Patent JP6926009
Kind Code:
B2
Abstract:
The purpose of the invention is to improve ignition properties while maintaining internal flame stabilization. Provided is a combustion burner (21) comprising a fuel nozzle (61), an air nozzle (62) for combustion, a plate-shaped first member (71) that is disposed in the fuel nozzle (61) along the fuel gas (301) injection direction (Jd), and a plate-shaped second member (72) that is disposed in the fuel nozzle (61) along the injection direction (Jd) and that is disposed adjacent to an adjacent burner side (Bs) of the first member (71) in the horizontal direction (Hd) orthogonal to the injection direction (Jd). An inclined face (71c) of the first member (71) and an inclined face (72c) of the second member (72) face the adjacent burner side (Bs) and are inclined toward the adjacent burner side (Bs) relative to the injection direction (Jd) of the fuel gas (301). A flat face (71d) and a flat face (72d) face a furnace wall side (Fs) in the horizontal direction (Hd) and extend in the injection direction (Jd).
