    • 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 gas turbine combustor for reducing a production of NOx. The combustor includes a head combustion chamber and a rear combustion chamber which is larger in diameter than the head combustion chamber. The head combustion chamber is provided with an axially extending hollow frustoconical tubular member to form an annular combustion space therein, air holes for axially jetting air into the annular combustion chamber, air holes formed on a peripheral wall for injecting air and a plurality of fuel nozzles projected into the annular combustion space for injecting fuel into vortex formed by the air jet and the injected air flow whereby the flame is stabilized and lean combustion can be effected. The rear combustion chamber has a fuel and air supply means on the upstream side which includes air inlets formed by whirling vanes and fuel nozzles disposed in the air inlets so that fuel and air are mixed well. The fuel and air mixture is jetted substantially axially while whirling it so that formation of hot spots is avoided and the NOx formation is extremely limited.

Primary air supply openings are formed in the tube portion defining the first combustion space, secondary air supply openings in the tube portion defining the second combustion space, and diluting air supply openings in the tube portion defining the main combustion space. To achieve effective cooling of the combustion gas within the combustion chamber, particularly in the second combustion space, and especially in the central portion thereof, and at the same time to maintain a stable combustion, the tube is formed so, and the cross-sectional areas of the primary, secondary and diluting air supply openings are dimensioned so, that 25 to 32% of the total amount of air supplied to the combustion chamber are used as primary air in the first combustion space, 38 to 50% as secondary air in the second combustion space, and less than 30% as diluting air in the main combustion space.
