Combustion chamber structure of gas turbine and nozzle thereof

The utility model discloses a gas turbine combustion chamber structure and a nozzle thereof, and relates to the technical field of gas turbines. The nozzle comprises a nozzle body; the first surface of the nozzle body is divided into an ignition area and a load area; the first face is the face, facing a flame tube, of the nozzle body. The fuel spray rods are arranged on the first surface of the spray head body, and the axial leads of the fuel spray rods are parallel to one another; the first fuel pipe is communicated with each fuel spray rod in the ignition area; and the second fuel pipe is communicated with each fuel spray rod in the load area. Through the arrangement of the ignition area and the load area, if the gas turbine is in the ignition or low working condition state, the fuel is conveyed to the combustion chamber only through the ignition area, and if the gas turbine is in the high working condition state, the fuel can be conveyed to the combustion chamber through the ignition area and the load area
