    • PROBLEM TO BE SOLVED: To provide a gas turbine combustor capable of stably burning low calory gas containing a large quantity of COsuch as blast furnace gas.SOLUTION: A burner structure in which gas fuel injection holes and air injection holes are alternately arranged in an inner peripheral swirler of a double-swirling burner constituted of the inner peripheral swirler and an outer peripheral swirler and gas injection holes are arranged in the outside outer peripheral swirler, is adopted as a basic configuration. Fuel injection holes for enhancing flame stability are provided at the radial direction inside of the inner peripheral swirler. Low calory gas can be stably burned by a mutual action of inner peripheral flame by the inner peripheral swirler and outer peripheral flame by the outer peripheral swirler. Especially, in the inner peripheral swirler, the gas injection holes and the air injection holes alternately arranged contribute to raising of a temperature of the inner peripheral flame for covering flame stability, and thus to enhancing of combustion stability. Further, by providing the fuel injection holes for enhancing flame stability, a flame temperature in a circulating gas region (flame stabilizing point) formed centrally in a radial direction of the burner, can be raised, and a gas turbine combustor capable of stably burning the low calory gas can be provided.
    • 要解决的问题:提供一种能够稳定地燃烧含有大量CO 2的低热量气体的燃气轮机燃烧器,例如高炉煤气。解决方案:一种燃烧器结构,其中气体燃料喷射孔和空气喷射孔交替地布置在内部 作为基本结构,采用由外周旋流器和外周旋流器构成的双回转燃烧器的周边旋流器和气体喷射孔配置在外侧外周旋流器中。 在内周旋流器的径向内设置用于提高火焰稳定性的燃料喷射孔。 低温卡路里气体可以通过内周旋流器的内周火焰和外周旋流器的外周火焰相互作用而稳定地燃烧。 特别地,在内周旋转器中,气体注入孔和空气注入孔交替布置有助于提高内周火焰的温度以覆盖火焰稳定性,从而提高燃烧稳定性。 此外,通过设置用于提高火焰稳定性的燃料喷射孔,可以提高在燃烧器的径向中央形成的循环气体区域(火焰稳定点)中的火焰温度,并且能够稳定地燃烧燃烧器 可以提供低热量气体。

    • PROBLEM TO BE SOLVED: To provide a combustion burner for a gas turbine capable of uniformizing fuel injected from injection holes and, thus, reducing NOx of a gas turbine combustor. SOLUTION: The combustion burner for the gas turbine includes: a plurality of turning blades 20 injecting fuel from the fuel injection holes 23, 24 to air or air fuel mixture made to flow from the upstream side and applying turing force to produce turing mixed air current; and a nozzle 21 in which the turning blades 20 are radially arranged on the outer peripheral face and a first fuel flow passage 26 guiding fuel to the fuel injection holes 23, 24 is provided inside. Cavities 25 communicated with the fuel injection holes 23, 24 are provided within the turning blades 20. At least two second fuel passages 27 are provided between the cavities 25 and the first fuel flow passage 26 along the axial direction. COPYRIGHT: (C)2011,JPO&INPIT
