摘要:
A combustor includes a first combustion chamber, a pre-mixing primary fuel-nozzle assembly associated with the first combustion chamber, a second combustion chamber, and a secondary fuel-nozzle assembly associated with the second combustion chamber. The pre-mixing primary fuel-nozzle assembly includes a number of vanes configured to swirl airflow, each vane comprising a number of fuel injection holes configured to inject fuel into the airflow.

The present application provides a method of mounting lip seals within a sleeve assembly of a fuel nozzle. The method may include the steps of sliding a first lip seal along a second diameter tube until the first lip seal contacts a first tube flange of a first diameter tube, sliding a seal spacer along the second diameter tube until the seal spacer contacts the first lip seal, and sliding a second lip seal along the second diameter tube until the second lip seal contacts the seal spacer.

A secondary nozzle for a combustor includes a feed nozzle having center channel surrounded by a fuel channel and a pilot channel. The secondary nozzle also includes a housing that surrounds at least a portion of the feed nozzle and includes a fuel inlet channel in a first plane and pilot inlet feed channel in a second plane different than the first plane, the fuel inlet channel and the pilot inlet feed channel interconnected to one another within the housing.

Methods and apparatus are provided for role-based shared access control to a protected system using reusable user identifiers while maintaining individual accountability. Role-based access control is provided for a protected system by receiving a request from an end user to access a given protected system; determining a role of the end user for the access to the given protected system; receiving a privileged reusable user identifier and password for the given protected system and role; and providing the privileged reusable user identifier and password to the given protected system on behalf of the end user. Role-based access control is also provided for a protected system by receiving a request to verify an end user requesting access to a given protected system; determining a role of the end user for the access to the given protected system; and providing a privileged reusable user identifier and password for the given protected system and role. A status of the privileged reusable user identifier and password can optionally be maintained. One or more events associated with the privileged reusable user identifier and password can be logged and investigated.

In one embodiment, a packet switching device assigns a same particular packet switching label to each particular route of a plurality of particular routes having the same one or more best paths, wherein the plurality of particular routes includes routes from at least two different forwarding groups. A forwarding group is defined as a specific route, one or more routes associated with a same customer edge router, or one or more routes associated with a single virtual routing and forwarding domain (VRF). The packet switching device advertises to other packet switching device(s) to add this same particular label to packets having one of the plurality of particular routes, which they do. The packet switching device then packet switches packets based on the particular label received in a label field in a header of these packets.

A fuel nozzle includes a fuel plenum, an outer body surrounding the fuel plenum, and bore holes that extend longitudinally through the outer body. The fuel nozzle also includes means for fixedly attaching the fuel plenum to the outer body and passages that provide fluid communication between the fuel plenum and the bore holes. A method for manufacturing a fuel nozzle includes drilling bore holes longitudinally through an outer body and drilling passages in the outer body to the bore holes. The method further includes inserting a fuel plenum into the outer body, wherein the passages provide a fluid communication between the bore holes and the fuel plenum, and attaching the fuel plenum to the outer body.
