Lean direct injection atomizer for gas turbine engines |
摘要 |
<p>A lean direct injection fuel nozzle (10) for a gas turbine is disclosed which includes a radially outer main fuel delivery system including a main inner air swirler (58) defined in part by a main inner air passage (66) having a radially inner wall (68) with a diverging downstream surface (68a), an intermediate air swirler (70) radially inward of the main inner air swirler for providing a cooling air flow along the downstream surface of the radially inner wall of the main inner air passage, and a radially inner pilot fuel delivery system radially inward of the intermediate air swirler.
