    • A method of starting a gas turbine plant, which plant has at least one combustor including a primary combustion chamber into which primary fuel nozzles open and a secondary combustion chamber into which secondary fuel nozzles open, a compressor for supplying the combustor with compressed combustion air, and a gas turbine driven by the combustion gas generated in the combustor and adapted to drive a load such as an electric power generator. When the gas turbine is being accelerated to a rated speed or while the load is still below a normal load range, a fuel is supplied only to the primary fuel nozzle, whereas, in other loaded operation range, the fuel is supplied to both the primary and secondary fuel nozzles. Before the fuel supply to the secondary fuel nozzles is commenced, a part of the compressed air is bled through at least one air bleed pipe leading from the compressor and having an air bleed valve. The air bleed valve is controlled in such a manner that the opening degree thereof is maximized when the fuel supply to the secondary fuel nozzles is commenced and is progressively decreased in accordance with the increase of the load such as to become substantially zero when the load has been increased to the normal load range.
    • 一种启动燃气轮机设备的方法,该设备具有至少一个燃烧器,该燃烧器包括初级燃料喷嘴打开的初级燃烧室和次级燃料喷嘴打开的二级燃烧室,用于向燃烧室供应压缩的燃烧空气的压缩机, 以及由在燃烧器中产生的燃烧气体驱动并适于驱动诸如发电机的负载的燃气轮机。 当燃气轮机正在加速到额定转速或负载仍然低于正常负载范围时,仅向主燃料喷嘴供应燃料,而在其他装载操作范围内,将燃料供应给主燃料 和二次燃料喷嘴。 在开始向二次燃料喷嘴供应燃料之前,一部分压缩空气通过至少一个从压缩机引出的排气管排出并具有排气阀。 控制排气阀,使得当向二次燃料喷嘴供应的燃料开始时,其开度最大化,并且随着负载的增加逐渐减小,当负载已经变为基本为零时 增加到正常负载范围。

    • A combined gas turbine plant comprises an air compressor, a combustor including a combustion chamber, a gas turbine, a steam turbine, and an exhaust heat recovery device having a denitration device and arranged at a location through which an exhaust gas passage for leading exhaust gas from the gas turbine to the atmosphere extends. An air extraction pipe equipped with a valve is provided for extracting a part of the air from the air compressor to prevent surging of the air compressor during starting of the plant, and another air extraction pipe equipped with a valve is provided for extracting a part of the air from an air passage extending from the compressor to the combustion chamber to improve stability of a flame and combustibility in the combustion chamber during the plant starting. The extraction pipes extend to and hence lead the extracted air into a portion of the exhaust gas passage located downstream of the denitration device.

    • A gas turbine combustor has an inner cylinder provided with a multiplicity of louvers for introducing cooling air and a plurality of air ports for introducing combustion air. The portions of the inner cylinder wall at both ends of each louver, where the concentration of stress due to thermal stress is heaviest, is reinforced by build-up welding thereby to prevent cracking at these portions of the cylinder wall. The build-up welding effectively stops the propagation of crack happened to be caused in the inner cylinder wall for any reason. The portions of the inner cylinder wall around the air ports also may be reinforced by build-up welding over the entire peripheries of these air ports. The build-up weld on the periphery of each air port prevents any crack from being propagated to the brim of each air port.
    • 燃气轮机燃烧器具有设置有用于引入冷却空气的多个百叶窗的内筒和用于引入燃烧空气的多个空气口。 由于热应力引起的应力集中在最重的每个百叶窗两端的内筒壁的部分通过堆积焊接加强,从而防止在气缸壁的这些部分处的开裂。 由于任何原因,积层焊接有效地阻止了内筒壁发生裂纹的传播。 围绕空气端口的内筒壁的部分也可以通过在这些空气端口的整个周边上的堆积焊接来加强。 每个空气端口周围的堆积焊缝防止任何裂纹传播到每个空气端口的边缘。

    • A gas turbine combustor has a plurality of burner units each having an inner tube defining a combustion chamber therein and an outer tube surrounding the inner tube coaxially therewith. A fuel is injected into the head portion of the inner tube and is burnt in the combustion chamber to produce hot combustion gases which are guided through a tail tube to stationary blades of a gas turbine. Combustion air is supplied through an annular passage between the inner and outer tubes from the area around the tail tube to the head portion of the inner tube. A flow-uniformalizing tube is disposed between the inner and outer tubes to cooperate with the inner tube to define therebetween an air passage. The flow-uniformalizing tube imparts a greater flow resistance to air flow from the back side of the tail tube than to the air flow from the side thereof diametrically remote from the back side, so that the flow velocity of the air flowing through the air passage is substantially uniformalized in the circumferential direction of the inner tube.
    • 燃气轮机燃烧器具有多个燃烧器单元,每个燃烧器单元具有在其中限定燃烧室的内管和与其同轴地围绕内管的外管。 燃料被喷射到内管的头部并在燃烧室中燃烧以产生热燃烧气体,其被引导通过尾管到燃气轮机的静止叶片。 燃烧空气通过内管和外管之间的环形通道从尾管周围的区域供应到内管的头部。 流动均匀化管设置在内管和外管之间以与内管配合以在其间限定空气通道。 流动均匀化管对来自尾管的后侧的气流赋予更大的流动阻力,而不是从其从背侧远离的一侧的空气流,使得流过空气通道的空气的流速 在内管的圆周方向上基本均匀化。
