ービン用燃焼器。 A swirler is provided around the fuel nozzle and causes combustion air supplied to the passage between the outer cylinder and the inner cylinder to flow into the inner cylinder, and an outer swirler is provided between the dome part of the inner cylinder and the swirler. A buttful whose peripheral edge is located inside the front surface of the dome part so that a part of the combustion air flows into the inner cylinder along the front surface of the dome part, and a buttful which extends from the inner outer peripheral edge of the swirler and has an outer peripheral edge. In a gas turbine combustor, a gas turbine combustor is provided with an inner baffle that is located inside from the front face and allows a part of the combustion air to flow into the inner cylinder along the front face of the buffle. A combustor for a gas turbine, characterized in that a flow guide is provided which is substantially parallel to the buttle so as to cover the dome part, and whose outer peripheral edge is positioned close to the inner peripheral edge of the dome part.
