Abstract
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.
