    Abstract: A system includes a gas turbine transition piece. The gas turbine transition piece includes a duct body having a forward end portion and an aft end portion. The duct body defines an enclosure for routing a flow of combustion products from a combustor to a turbine first stage nozzle, and the forward end portion includes a straight portion extending in a downstream direction of the flow. The gas turbine transition piece also includes a first set of dilution holes formed in the forward end portion and arranged in a first pattern configured to reduce emissions. In certain embodiments, the gas turbine transition piece includes a second set of dilution holes formed in the aft end portion and arranged in a second pattern configured to alter the thermal gradient of the combustion gases.

    Abstract: A system and method for generating steam during gas turbine low-load operating conditions is disclosed herein. The system includes a gas turbine having a compressor, a combustor, a turbine and at least one bleed air extraction port in fluid communication with the compressor, a compressor discharge casing or the combustor. The system further includes a premix duct burner downstream from the turbine and upstream from a heat recovery steam generator of the gas turbine. During operation, the premix duct burner increases temperature of combustion gases flowing from the turbine and into the heat recovery steam generator and compressed air flows out of the bleed air extraction port so as to reduce pressure within the compressor, the compressor discharge casing or the combustor during low-load gas turbine operating conditions.
