Abstract
Official abstract text for this publication.
A method for assembling a fuel distribution system for a turbomachine fuel injector includes inserting a liquid fuel distributor into an interior cavity of a shroud to create a liquid fuel distribution circuit between the liquid fuel distributor and the shroud and inserting a gas fuel distributor into the interior cavity of the shroud and into an interior cavity of the liquid fuel distributor to create a gas fuel distribution circuit between the gas fuel distributor and the liquid fuel distributor. The method includes inserting a fuel transfer tube into an outer diameter of the shroud. The method includes brazing or shrink fitting at least one of the fuel transfer tube, the gas fuel distributor, or the liquid fuel distributor to the shroud.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for assembling a fuel distribution system for a turbomachine fuel injector, comprising: inserting a liquid fuel distributor into an interior cavity of a shroud to create a liquid fuel distribution circuit between the liquid fuel distributor and the shroud; inserting a gas fuel distributor into the interior cavity of the shroud and into an interior cavity of the liquid fuel distributor to create a gas fuel distribution circuit between the gas fuel distributor and the liquid fuel distributor; inserting a fuel transfer tube into an outer diameter wall of the shroud, the fuel transfer tube including a liquid fuel channel configured to be in fluid communication with the liquid fuel distribution circuit and a gas fuel channel configured to be in fluid communication with the gas fuel distribution circuit; and brazing or shrink fitting at least one of the fuel transfer tube, the gas fuel distributor, or the liquid fuel distributor to the shroud. 2. The method of claim 1 , further comprising press fitting at least one of the liquid fuel distributor or the gas fuel distributor to the shroud. 3. The method of claim 2 , wherein press fitting includes heating the shroud before inserting the liquid fuel distributor so that the liquid fuel distributor can be inserted and cooling the shroud after inserting the liquid fuel distributor. 4. The method of claim 3 , wherein press fitting includes heating the liquid fuel distributor and the shroud before inserting the gas fuel distributor so that the gas fuel distributor can be inserted and cooling the liquid fuel distributor and the shroud after inserting the gas fuel distributor. 5. The method of claim 1 , further comprising applying a braze material to at least one of the liquid fuel distributor, gas fuel distributor, or the fuel transfer tube before inserting into the shroud. 6. The method of claim 5 , wherein applying braze material includes applying braze material at a predetermined location to create one or more braze joints.
