Combustor with secondary fuel nozzle in dilution fence

A gas turbine comprising:

• a compressor section;
• and
• a combustor receiving a flow of compressed air from the compressor section,
• the combustor including:
• a combustor liner having an outer liner and an inner liner defining a combustion chamber therebetween, at least one of the outer liner or the inner liner including a dilution fence arranged in a dilution zone of the combustion chamber, the dilution fence extending into the combustion chamber and having at least one secondary fuel nozzle opening therethrough and having at least one dilution opening therethrough;
• a dome assembly arranged at an upstream end of the combustion chamber and extending between the outer liner and the inner liner;
• at least one main mixer assembly arranged through the dome assembly, the at least one main mixer assembly including a fuel nozzle assembly coupled thereto, a first portion of the compressed air received by the combustor from the compressor section being provided to the at least one main mixer assembly;
• an outer casing surrounding the outer liner and an inner casing surrounding the inner liner, an outer flow passage being defined between the outer casing and the outer liner, and an inner flow passage being defined between the inner casing and the inner liner, a second portion of the compressed air received by the combustor being provided to the outer flow passage and being provided to the inner flow passage;
• and
• at least one secondary fuel nozzle arranged through the at least one secondary fuel nozzle opening of the dilution fence, the at least one secondary fuel nozzle providing a flow of fuel to the combustion chamber in the dilution zone, and a flow of dilution air being provided to the combustion chamber through at least one of the secondary fuel nozzle opening or the at least one dilution opening through the dilution fence,
• wherein the dilution fence comprises a dilution fence upstream portion extending into the combustion chamber at a downstream angle, and a dilution fence downstream portion extending into the combustion chamber at an upstream angle, the dilution fence upstream portion and the dilution fence downstream portion being joined together at an inner end of the dilution fence.
