METHODS OF IGNITING LIQUID FUEL IN A TURBOMACHINE

A method of igniting liquid fuel (58) in a turbomachine combustor (22) is provided. The method includes a step of initiating a flow of gaseous fuel (28) from a gaseous fuel supply (228) to a gaseous fuel nozzle (322). The method further includes a step of initiating a flow of liquid fuel (58) from a...

Beschreibung
Zusammenfassung:	A method of igniting liquid fuel (58) in a turbomachine combustor (22) is provided. The method includes a step of initiating a flow of gaseous fuel (28) from a gaseous fuel supply (228) to a gaseous fuel nozzle (322). The method further includes a step of initiating a flow of liquid fuel (58) from a liquid fuel supply (158) to a primary liquid fuel cartridge (358). After initiating both the flow of gaseous fuel (28) and the flow of liquid fuel (58), the method includes a step of igniting the flow of gaseous fuel (28) and the flow of liquid fuel (58) with an igniter (370). The method further includes a step of terminating the flow of gaseous fuel (28) from the gaseous fuel supply (228) to the gaseous fuel nozzle (322).
