  • HEAD END TURNING SCOOP FOR A GAS TURBINE

    In a combustor (10) for a gas turbine, a head end turning scoop (12) is provided associated with at least one premix nozzle (22,24), each scoop (12) being U-shaped and having a first leg (58), a second leg (60), and a curved base portion (62), each scoop (12) disposed in a flow volume (44), wherein the first leg (58) is disposed adjacent to the cap outer body (68) and the second leg (60) is disposed adjacent to an upstream entry plane (66) of the premixer nozzle entrance (49) with which the scoop (12) is associated. Compressed air is guided from the liner channel (36), around the scoop (12), and into the upstream entry plane (66) of the premixer nozzle entrance (49). Flow of compressed air into the premixer nozzle entrance (49) is substantially even per premixer blade passage (54) to provide a controlled, air-fuel mixture to the nozzle tip (50).

  • MEASUREMENT SYSTEM BASED ON DEEP-MUSCLE SEMG ELECTRICAL SIGNAL

    A measurement system based on a deep-muscle sEMG electrical signal, comprising: a measurement electrode (101); an EMG signal acquisition device (102); and a data processing device (103). The measurement electrode (101) is a monopolar needle electrode or a wire electrode; the measurement electrode (101) is connected to the EMG signal acquisition device (102); the EMG signal acquisition device (102) is connected to the data processing device (103); the data processing device (103) is used for obtaining, according to an EMG signal acquired by the EMG signal acquisition device (102), an indicator parameter corresponding to sEMG. The measurement system based on a deep-muscle sEMG electrical signal uses the monopolar needle electrode or the wire electrode to replace an existing surface electrode, and can be used to detect electrical activity in single target muscles and deep muscles, and compensate for the shortcoming in which a surface electrode can only be used to record the sum of electrical activities in sub-electrode top layer muscle groups, and has better clinical application value.

  • METHOD OF OPTIMIZING PREMIX FUEL NOZZLES FOR A GAS TURBINE

    A method of optimizing a premix fuel nozzle (12) for a gas turbine is provided. When the gas turbine is in operation, the nozzle (12) comprises an axial flow field of air and fuel mixture flowing through a burner tube (25) and around a nozzle tip (24), and at least two recirculation zones with at least two different radial extents as part of a toroidal vortex generated on the nozzle tip (24) to provide strong flame stability and flame propagation.

  • PREMIX FUEL NOZZLE FOR A GAS TURBINE AND COMBUSTOR

    A nozzle tip (24) for a premix fuel nozzle (12, 22) is provided. The nozzle tip (24) includes an outer body (26) having an outer body external face (36) facing the downstream end of a burner tube (25). The outer body external face (36) has a smaller cross-sectional area than the cross-sectional area of the burner tube (25), and at least one segment (40) radiates radially outwardly toward the internal wall (27) of the burner tube (25) from the outer body (26), wherein each segment (40) has a proximal end (44) disposed adjacently to the outer body external face (36) and a distal end (46) disposed in a direction toward the burner tube (25). Each segment (40) has a segment downstream face (48) angled relatively to the longitudinal axis (B) of the burner tube (25) towards the downstream end of the burner tube (25). When the gas turbine is in operation, an axial flow field of an air and fuel mixture flows through the burner tube (25) and around the nozzle tip (24), and two or more recirculation zones of different radial extent are generated on the nozzle tip (24) by the segments (40) to provide strong flame holding and flame propagation.
