A control method for a gas turbine combustor including an air-hole plate having a plurality of air holes formed therein, and a plurality of fuel nozzles corresponding to respective ones of the plurality of air holes. The gas turbine combustor is operable to combust a hydrogen fuel and a fuel other than the hydrogen fuel. The air holes include: first air holes having, among passageways from an entry end to an exit end, an inclined passageway extending in a direction inclined with respect to the central axis of the air-hole plate in a region including at least the exit end; and second air holes extending in parallel to the central axis. The fuel nozzles include first fuel nozzles corresponding to respective first air holes, and second fuel nozzles corresponding to respective second air holes. During hydrogen fuel firing, the hydrogen fuel is not supplied to the first fuel nozzles.
A control method for a gas turbine combustor that includes an air-hole plate in which a plurality of air holes are formed and a plurality of fuel nozzles corresponding to the plurality of air holes, respectively, and that combusts a hydrogen fuel and another fuel other than the hydrogen fuel, in which the plurality of air holes include a plurality of first air holes each having an inclined passageway that extends in a direction inclined with respect to a central axis of the air-hole plate in a region including at least an exit end in a passageway from an entry end to the exit end, and a plurality of second air holes that extend parallel to the central axis, and the plurality of fuel nozzles include a plurality of first fuel nozzles corresponding to the plurality of first air holes, respectively, and a plurality of second fuel nozzles corresponding to the plurality of second air holes, respectively, the control method comprising:
A control device for a gas turbine combustor, the control device being for controlling combustion in the gas turbine combustor that includes an air-hole plate in which a plurality of air holes are formed and a plurality of fuel nozzles corresponding to the plurality of air holes, respectively, and that combusts a hydrogen fuel and another fuel other than the hydrogen fuel, in which the plurality of air holes include a plurality of first air holes each having an inclined passageway that extends in a direction inclined with respect to a central axis of the air-hole plate in a region including at least an exit end in a passageway from an entry end to the exit end, and a plurality of second air holes that extend parallel to the central axis, and the plurality of fuel nozzles include a plurality of first fuel nozzles corresponding to the plurality of first air holes, respectively, and a plurality of second fuel nozzles corresponding to the plurality of second air holes, respectively, the control device comprising:
