Abstract:
The present invention is provided with a plurality of splitters (5), (6), (7) provided to the distal-end side inside a fuel nozzle (3) such that the longitudinal axes of the splitters (5), (6), (7) extend from the lower-wall part (3a) of the fuel nozzle (3) to the upper-wall part (3b) of the fuel nozzle (3), the splitters (5), (6), (7) dividing the flow of fuel gas by widened parts that increase in width along the direction in which the fuel gas flows. The splitters include: slitted splitters (5), (6) in which slits (SL) are formed for partially reducing the width of the fuel-gas-flow downstream ends of the widened parts; and non-slitted splitters (7) disposed adjacent to the slitted splitters (5), (6), the non-slitted splitters (7) being configured such that the width of the fuel-gas-flow downstream ends of the widened parts is fixed along the longitudinal-axis direction.
