Method for igniting the combustion chamber of a gas turbine unit and an ignition device for carrying out the method

In a method for igniting the combustion chamber of a gas turbine unit, a safely working ignition and a long lifetime of the ignition device ( 10 ) is achieved by discharging a compressed gas with a supercritical pressure ratio through a nozzle ( 21 ) and heating it up to a temperature sufficient to...

More Information
Summary:In a method for igniting the combustion chamber of a gas turbine unit, a safely working ignition and a long lifetime of the ignition device ( 10 ) is achieved by discharging a compressed gas with a supercritical pressure ratio through a nozzle ( 21 ) and heating it up to a temperature sufficient to ignite hydrocarbons by interacting with a resonance tube ( 19 ) arranged behind said nozzle ( 21 ), and using said heated-up gas to directly or indirectly ignite a fuel/air mixture introduced into said combustion chamber.
