FUEL INJECTOR HAVING IGNITOR FOR IGNITING COMBUSTOR OF GAS TURBINE

摘要

PROBLEM TO BE SOLVED: To provide a fuel injector for igniting a combustor of a gas turbine.SOLUTION: There is provided an improved system of a fuel injector 68 for igniting a combustor 22 of a gas turbine, which eliminates the need for a breach loaded igniter and cross fire tubes thereby avoiding increase in cost and undesirable restrictions in combustion design. The fuel injector 68 for the combustor 22 of the gas turbine includes an annular main body. A fluid circuit extends at least partially through the main body. An axially extending inner body extends within the main body. The inner body at least partially defines an inner chamber that extends at least partially through the inner body. The inner chamber is in fluid communication with the fluid circuit. A retractable igniter extends linearly outward from the inner chamber when the fluid circuit is charged.
