Title:
COMBUSTION BURNER AND BOILER
Document Type and Number:
Japanese Patent JP2022055568
Kind Code:
A
Abstract:
To suppress ignitability or flame retention capability from decreasing, by eliminating mutual interference of fuel-air mixture recirculation regions formed by neighboring splitters.SOLUTION: A combustion burner according to an embodiment of the present invention comprises a fuel nozzle that ejects fuel gas formed by mixing fuel and air, a combustion air nozzle that ejects combustion air from outside the fuel nozzle, a first member disposed inside the fuel nozzle and having a first slope sloping with respect to a fuel stream and a first slope end whereat the sloping of the first slope ends, and a second member having a second slope disposed downstream relative to the first slope in the direction of the fuel stream and sloping with respect to the fuel gas stream, and a second slope end whereat the sloping of the second slope ends. The first member and the second member are adjacent to each other, and either the first slope or the second slope is formed only on the face of the first member facing the second member or on the face of the second member facing the first member.SELECTED DRAWING: Figure 2
