    • 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 method and system for effecting control governing of a steam turbine wherein the steam chamber of a first stage nozzle is divided into a plurality of steam compartments, control valves each connected to one of the steam compartments are individually operated for controlling the flow rate of steam introduced into the turbine, and the governing of the nozzle is effected by adjusting the flow rate of steam in accordance with a load. At low load, the degree of opening of the control valves is kept constant and the turbine is driven by steam of a reduced pressure by reducing the pressure of the steam at the inlet of the turbine so as to maintain, in a low load region, the volume flow rate of steam for a high load region. To cope with a change in the value of the load, the degree of opening corresponding to a predetermined change in the value of the load is set beforehand for each control valve. When the change in the value of the load is smaller than the predetermined change in the value of the load, the degree of opening of the control valve involved is adjusted. Conversely, when the change in the value of the load is greater than the predetermined change in the value of the load, the pressure of the steam at the inlet of the turbine is controlled.
    • 一种用于实现蒸汽轮机的控制控制的方法和系统,其中第一级喷嘴的蒸汽室被分成多个蒸汽隔间,各自连接到一个蒸汽隔间的控制阀被单独操作以控制蒸汽的流量 引入涡轮机,并且通过根据负载调节蒸汽的流量来实现喷嘴的调节。 在低负载下,控制阀的开度保持恒定,并且通过减小涡轮入口处的蒸汽的压力使涡轮由减压蒸汽驱动,以便在低负荷区域中保持, 高负荷区域的蒸汽体积流量。 为了应对负载值的变化,对于每个控制阀,预先设定对应于负载值的预定变化的开度。 当负载值的变化小于负载值的预定变化时,调节所涉及的控制阀的开度。 相反,当负载值的变化大于负载值的预定变化时,控制涡轮入口处的蒸汽的压力。
