摘要： A combustion burner includes a fuel nozzle configured to blow in fuel gas of solid fuel and air, a combustion air nozzle configured to blow in air from the outside of the fuel nozzle, and at least one flame stabilizer arranged on the axial center side at a distal end of the fuel nozzle. The flame stabilizer is arranged at the distal end, and has a flame stabilizing member whose width increases in a direction toward the distal end, and a straightening vane having a plate shape and being arranged on an extension of the flame stabilizing member on the upstream side in a flow direction of the fuel gas. An abrasion-resistant member is arranged on a wide width surface of the flame stabilizer, and an abrasion-resistant member is arranged on at least a part of the straightening vane.

摘要： A combustion burner includes a plurality of splitters (5), (6), (7) configured to divide a fuel gas flow by a widened portion where a width of the widened portion increases as the widened portion extends in the direction of the fuel gas flow. The splitters include: slitted splitters (5), (6) configured to slits (SL) at a downstream end in the fuel gas flow; and non-slitted splitters (7) configured to adjacently to the slitted splitters (5), (6), each of the non-slitted splitters (7) configured to the widened portion at a downstream end in the fuel gas flow, and configured to a fixed width in a direction of the longitudinal axis.
