20120111021 | Integrated Turbomachine Oxygen Plant - An integrated turbomachine oxygen plant includes a turbomachine and an air separation unit. One or more compressor pathways flow compressed air from a compressor through one or more of a combustor and a turbine expander to cool the combustor and/or the turbine expander. An air separation unit is operably connected to the one or more compressor pathways and is configured to separate the compressed air into oxygen and oxygen-depleted air. A method of air separation in an integrated turbomachine oxygen plant includes compressing a flow of air in a compressor of a turbomachine. The compressed flow of air is flowed through one or more of a combustor and a turbine expander of the turbomachine to cool the combustor and/or the turbine expander. The compressed flow of air is directed to an air separation unit and is separated into oxygen and oxygen-depleted air. | 05-10-2012 |
20130047629 | INTEGRATED TURBOMACHINE PLANT - An integrated turbomachine plant is provided and includes a combustor a turbomachine operably connected to the combustor and including a compressor and a turbine expander, a pathway to flow compressed air from the compressor through the turbine expander to heat the compressed air, an additional pathway by which high temperature fluids output from the turbomachine are employed to heat the compressed air and an air separation unit operably connected to the pathway and configured to separate the heated compressed air into oxygen and oxygen-depleted air. | 02-28-2013 |
20130061600 | METHOD OF CONTROLLING TEMPERATURE OF GAS TURBINE COMPONENTS USING A COMPRESSED MOISURIZED COOLANT - A method and apparatus for controlling a temperature a component of a gas turbine is disclosed. A compressed gas for use as a coolant is provided. The coolant is moisturized at a moisturizeing unit. A circulating unit circulates the moisturized coolant to the component of the gas turbine to control the temperature of the component. The coolant can be air, nitrogen, and a mixture of air and nitrogen in various embodiments. The component of the turbine can be a blade of a turbine section of the gas turbine, a turbine nozzle and a combustor, for example. A combustor can combust a mixture of fuel and the moisturized compressed coolant gas to reduce a NOx emission of the gas turbine. | 03-14-2013 |
