Radially Stacked Fuel Injection Module for a Segmented Annular Combustion System
First Claim
1. A fuel injection module, comprising:
- a bundled tube fuel nozzle portion including a plurality of tubes that extends through a bundled tube fuel plenum defined within a housing body of the fuel injection module; and
a plurality of fuel injection lances extending from the housing body, wherein a first subset of fuel injection lances is in fluid communication with a first injector fuel plenum defined within the housing body, and a second subset of fuel injection lances is in fluid communication with a second injector fuel plenum defined within the housing body.

Abstract
The present disclosure is directed to a radially stacked fuel injection module for a segmented annular combustion system. The fuel injection module includes a bundled tube fuel nozzle portion and a plurality of fuel injection lances. In one instance, a first set of fuel injection lances and a second set of fuel injection lances share a housing with the bundled tube fuel nozzle. The first and second sets of fuel injection lances are radially stacked, each set of lances being in communication with a respective injector fuel plenum. The fuel injection lances deliver fuel to a respective premixing channel formed between the side walls of an integrated combustor nozzle, an aft end of which defines a turbine nozzle. In another instance, the bundled tube fuel nozzle may be provided as a radially inner fuel nozzle and a radially outer fuel nozzle, each with a respective bundled tube fuel plenum.

12. An annular combustion system segment, comprising:
-
a first integrated combustor nozzle including an inner liner segment, an outer liner segment, a pressure side wall, a suction side wall, a plurality of premixing channels defined between the pressure side wall and the suction side wall, and a downstream end portion defining a first turbine nozzle, wherein the plurality of premixing channels comprises a radially inner subset of premixing channels and a radially outer subset of premixing channels; a first fuel injection module extending radially upwardly from the inner liner segment towards the outer liner segment, wherein the first fuel injection module includes a bundled tube fuel nozzle portion and a first plurality of fuel injection lances, wherein each fuel injection lance of the first plurality of fuel injection lances is in fluid communication with a respective premixing channel of the radially inner subset of premixing channels; and a second fuel injection module extending radially upwardly from the first fuel injection module toward the outer liner segment, wherein the second fuel injection module includes a bundled tube fuel nozzle portion and a second plurality of fuel injection lances, wherein each fuel injection lance of the second plurality of fuel injection lances is in fluid communication with a respective premixing channel of the radially outer subset of premixing channels. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
