Combustor and method for distributing fuel in the combustor

摘要

A combustor includes a plurality of tubes arranged in a tube bundle and supported by at least one plate that extends radially within the combustor, wherein each tube includes an upstream end axially separated from a downstream end and provides fluid communication through the tube bundle. A flow conditioner extends upstream from the upstream end of one or more of the plurality of tubes, and a radial passage extends through the flow conditioner. A method for distributing fuel in a combustor including flowing a working fluid through a flow conditioner that extends from a tube that is configured in a tube bundle comprising a plurality of tubes and that is supported by at least one plate. The flow conditioner includes at least one radial passage to impart radial swirl to the working fluid. Flowing a fuel through an annular insert that is at least partially surrounded by the flow conditioner.

主权项

1. A combuster, comprising:
a. a plurality of tubes arranged in a tube bundle and supported by at least one plate extending radially within the combustor, wherein each tube includes an upstream end axially separated from a downstream end and a fuel port defined by the tube between the upstream end and the downstream end, wherein the fuel port provides for fluid communication into the tube, wherein each tube extends parallel to an adjacent tube of the plurality of tubes; b. a first flow conditioner that extends upstream from the upstream end of a first tube of the plurality of tubes, wherein the first flow conditioner defines a plurality of radial passages annularly arranged thereabout, wherein the first flow conditioner provides for a first flow rate of a compressed working fluid through the first tube; c. a second flow conditioner that extends upstream from the upstream end of a second tube of the plurality of tubes, wherein the second flow conditioner defines a plurality of radial passages annularly arranged thereabout, wherein the second flow conditioner provides for a second flow rate of a compressed working fluid through the second tube; d. a first liquid fuel atomizer disposed upstream from an inlet of the first flow conditioner: e. a second liquid fuel atomizer disposed upstream from an inlet of the second flow conditioner; and f. a fuel plenum that circumferentially surrounds the tubes, wherein each fuel port is in fluid communication with the fuel plenum.
