Abstract
An injector assembly for a gas turbine for introducing a gaseous fuel, liquid fuel and air into a combustion chamber, includes an injector shaft and an injector main body aligned along an injector longitudinal axis. The injector main body includes a first gas duct arranged centrally on the injector longitudinal axis, for introducing a gas flow into the combustion chamber; an air duct arranged radially around the outside of the first gas duct, and a liquid fuel injection arranged radially around the first gas duct for introducing the liquid fuel into the combustion chamber. The injector assembly introduces the gaseous fuel. The injector assembly is switchable between two configurations during operation: in a first configuration, air flows through the first gas duct, as an air injection; in a second configuration, the gaseous fuel flows through, as a gas fuel injection.
