摘要:
By blending a quantity of synthetic cyclo-paraffinic kerosene fuel blending component comprising at least 99.5 mass% of carbon and hydrogen content and at least 50 mass% of cyclo-paraffin into kerosene base fuel, kerosene based-propulsion fuels can be upgraded to higher quality kerosene based-propulsion fuels such as jet fuel or rocket fuel to meet certain specification and/or increase volumetric energy content of the propulsion fuel.

A method and s\ stem for sυpplying fuel are provided. The fuel supply system includes a supply of a flow of fuel wherein the fuel includes an amount of moisture in a first predetermined range, a supply of a flow of gas wherein the gas includes an amount of moisture in a second predetermined range and wherein the second predetermined range is less than the first predetermined range. The fuel supply system further includes a vessel configured to receive the flow of fuel and the flow of gas, mix the flow of fuel and the flow of gas, and separate the flow of fuel from the flow of gas wherein moisture is transferred from the flow of fuel to the flow of gas.
摘要:
A gas stream with a reduced oxygen concentration relative to ambient air is used to vaporize a liquid fuel or liquified hydrocarbon gas, or is mixed with a vaporized gas, and the reduced oxygen vaporized fuel gas is fed to a combustion device such as a premixed or diffusion combustor. Preferably, the oxygen content of the gas stream is less than the limited oxygen index. By mixing the fuel with a gas stream that has an appropriately reduced oxygen content, auto-ignition prior to the flame front can be avoided. In some embodiements, the reduced oxygen stream is generated from an air separator or taken from the exhaust of the combustion device.

摘要:
A method of co-firing fuel within a gas turbine engine (5). The method may include injecting a first fuel (80) into a combustion system (20) of a gas turbine engine. The first fuel may include a high energy liquid fuel. The method may also include injecting a second fuel (90) into the combustion system. The second fuel may include a gaseous low Wobbe fuel. Only the first fuel may be injected during a first mode of operation. The first fuel and the second fuel may be injected simultaneously and discretely during a second mode of operation.
摘要:
Systems, methods, and apparatus are provided for generating power in low emission turbine systems and separating the exhaust into rich CO2 and lean CO2 streams. In one or more embodiments, the exhaust is separated at an elevated pressure, such as between a high-pressure expansion stage and a low-pressure expansion stage.
