PURPOSE:To promote atomization of fuel at the time of starting a gas turbine, by attaching an injection nozzle to the top of a vibration pipe that is projected into a combustion chamber of the gas turbine. CONSTITUTION:A vibration pipe 2 is projected into a combustion chamber R of a gas turbine, and an injection nozzle 15 communicated with a fluid passage 10 formed in the vibration pipe 2 is attached to the top of the vibration pipe 2. At the time of starting the gas turbine, voltage is applied to a laminated piezo- electric element 4 fixed to the base portion of the vibration pipe 2, whereby vibration is caused at the injection nozzle 15 attached to the top of the vibration pipe 2. Thus, it is enabled to promote atomization of liquid fuel. |
