摘要： A fuel nozzle system for enabling a gas turbine to start and operate on low-Btu fuel includes a primary tip having primary fuel orifices and a primary fuel passage in fluid communication with the primary fuel orifices, and a fuel circuit capable of controlling flow rates of a first and second low-Btu fuel gases flowing into the fuel nozzle. The system is capable of operating at an ignition status, in which at least the first low-Btu fuel gas is fed to the primary fuel orifices and ignited to start the gas turbine, and a baseload status, in which at least the second low-Btu fuel gas is fired at baseload. The low-Btu fuel gas ignited at the ignition status has a content of the first low-Btu fuel gas higher than that of the low-Btu fuel gas fired at the baseload status. Methods for using the system are also provided.

摘要： A fuel supply system is provided having a first fuel gas compressor configured to be driven by a motor and a second fuel gas compressor configured to be driven by a shaft of a gas turbine system. The first fuel gas compressor and the second fuel gas compressor are configured to supply a pressurized fuel flow to a combustor of the gas turbine system, and the first fuel gas compressor and the second fuel gas compressor are coupled to one another in series.

摘要： A power generation system including a gasifier for receiving and converting coal-water slurry to a fuel stream, and a quench device for cooling the fuel stream to generate a cooled down fuel stream. The quench device includes a water quench ring, which is able to spray water to cool the fuel stream passing therethrough. The system further includes a separating device, which includes a separator and a high temperature filter for removing rough and fine particles from the cooled down fuel stream respectively, an expander for receiving and utilizing energy in the fuel stream with solids removed to generate power, during which temperature and pressure of the fuel stream drop and an expanded fuel stream is generated, an acid gas removal unit for removing acid gases from the expanded fuel stream, and a gas turbine combine cycle for generating power from the fuel stream with acid gases removed.
