Abstract: A system and a method of generating energy in a power plant using a turbine are provided. The system includes an air separation unit providing an oxygen output; a plasma generator that is capable of generating plasma; and a combustor configured to receive oxygen and to combust a fuel stream in the presence of the plasma, so as to maintain a stable flame, generating an exhaust gas. The system can further include a water condensation system, fluidly-coupled to the combustor, that is capable of producing a high-content carbon dioxide stream that is substantially free of oxygen. The method of generating energy in a power plant includes the steps of operating an air separation unit to separate oxygen from air, combusting a fuel stream in a combustor in the presence of oxygen, and generating an exhaust gas from the combustion. The exhaust gas can be used in a turbine to generate electricity. A plasma is generated inside the combustor, and a stable flame is maintained in the combustor.

The exit section includes a plurality of jets formed in a predefined pattern on an exit surface. A ratio of a core area of the plurality of jets to an exit surface area is greater than 0.25.

Abstract: A combustion nozzle includes at least one passage having a mixing section and an exit section. The mixing section includes an air inlet, and a fuel inlet. The mixing section has a first length and a first diameter. The exit section has a second length different from the first length, and a second diameter different from the first diameter.

Abstract: System and methods for hydrogen assisted oxy-fuel combustion are provided. The system includes a combustor, an air separation unit, a fuel stream source, and a condenser. The combustor includes an oxygen input port, a fuel stream input port, a carbon dioxide input port, and an exhaust output port. The air separation unit is in fluid communication with the combustor via the oxygen input port of the combustor. The fuel stream source is in fluid communication with the combustor via the fuel stream input port and includes a fuel source and a hydrogen source. The condenser is disposed to receive an exhaust from the combustor via the exhaust output port and to return an output stream to the combustor via the carbon dioxide input port. The method includes combusting a fuel stream in a combustor in the presence of an oxidizer to generate an exhaust gas.
