  • Patent number: 9890713
    Abstract: A silencer apparatus for a gas turbine inlet system ducting is disclosed. The inlet ducting contains a main silencer and a pre-silencer, and Inlet Bleed Heat (“IBH”) located between the silencers. The pre-silencer decreases the noise level from the turbine compressor and makes the air flow/temperature profiles more uniform. The main silencer reduces noise from the IBH and the remaining noise from the compressor to an appropriate level. The main silencer is comprised of a first plurality of sound-absorbing splitters disposed along the gas flow direction in the gas turbine inlet ducting. The pre-silencer is comprised of a second plurality of sound-absorbing splitters disposed along the gas flow direction in the gas turbine inlet ducting, but staggered with respect to the first plurality of splitters to thereby block a direct line of travel for noise acoustical waves from the compressor travelling opposite the gas flow direction in the inlet ducting.

  • Patent number: 9890710
    Abstract: A power plant includes a gas turbine having a combustor downstream from a compressor, a turbine disposed downstream from the combustor and an exhaust duct downstream from an outlet of the turbine. The combustor includes an extraction port that is in fluid communication with a hot gas path of the combustor. The extraction port defines a flow path for a stream of combustion gas to flow out of the hot gas path. The exhaust duct receives exhaust gas from the turbine outlet. A coolant injection system injects a coolant into the stream of combustion gas upstream from the exhaust duct such that the stream of combustion gas blends with the exhaust gas from the turbine within the exhaust duct and forms an exhaust gas mixture within the exhaust duct. A heat exchanger is disposed downstream from the exhaust duct and receives the exhaust gas mixture from the exhaust duct.
