<p>A combustor with a burner adapted to maintain combustion stability while suppressing a quantitative increase of fueling nozzles due to enlarging, and a remodeling method for the burner. A burner includes: an air hole member with a plurality of air holes, each of which is provided at an upstream side of combustion gases generated by a combustion chamber; a first fueling nozzle for jetting a fuel in a direction crossing a central axis of the burner towards at least two air holes; a plurality of second fueling nozzles each provided for one of the remaining air holes and formed for jetting the fuel in a direction routed along the burner axis towards the corresponding air hole; a fuel header for distributing the fuel to the first fueling nozzle and each of the second fueling nozzles; and a fuel header storage unit that shrouds the fuel header, the first fueling nozzle, and second fueling nozzle, and having an air inflow hole.</p> |
