FIELD: fuel combustion methods and devices.
SUBSTANCE: invention relates to a fuel injector of a gas turbine engine, and in particular to a fuel injector of a gas turbine with a removable pilot liquid tube. Pilot liquid tube having a pilot liquid fuel inlet, a pilot liquid fuel conduit, a pilot liquid fuel nozzle, and a shroud configured to shield the pilot liquid fuel nozzle. Fuel injector of a gas turbine engine comprising a pilot liquid tube is also provided in the present invention. Pilot liquid tube may be installed and/or removed from an injector of a gas turbine engine while the shroud remains fixed to pilot liquid fuel conduit.
EFFECT: invention significantly reduce heat transfer to the pilot liquid fuel conduit and inhibit coking.
