A staged fuel injector is disclosed that includes a main fuel circuit for
delivering fuel to a main fuel atomizer and a pilot fuel circuit for
delivering fuel to a pilot fuel atomizer located radially inward of the
main fuel atomizer. The pilot fuel circuit is in close proximity to the
main fuel circuit enroute to the pilot fuel atomizer so that the pilot
fuel flow cools stagnant fuel located within the main fuel circuit during
low engine power operation to prevent coking.
