摘要： Steam introduced into a turbine casing from a steam inlet is longitudinally divided and each divided steam portion flows in respective first stages which are disposed on the shaft adjacent to each other. The shaft and a plurality of disks which are manufactured independently are made integral by a thermal shrink. In order to reduce the thermal distortion effects on the shaft caused by keys interconnecting the disks and shaft, first key grooves formed on an outer surface of the shaft and an inner surface of the disks of one first stage and a first key closely disposed in the first key grooves are arranged in symmetry with respect to the center of the shaft, to second key grooves formed on an inner surface of the disk of the other first stage with a second key closely disposed in the second grooves. Other preferred embodiments include dummy grooves and keys to balance the thermal distortion effects of the keys interconnecting the disks and shaft.

摘要： 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.
摘要翻译： 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。

摘要： A gas turbine combustor having a head combustion chamber and a rear combustion chamber, with a plurality of air supply ports arranged in a circumferential wall of the rear combustion chamber, and a fuel nozzle. An outer cylinder forms a cylindrical air flow passage between the inner cylinder and the outer cylinder. A cylindrical control member is provided which is adapted to be movable in an axial direction for regulating an opening of the air supply ports. The control member is supported by a supporting means which is adapted to maintain a gap between the control member and the wall of the rear combustion chamber. The supporting member includes a flexible member for absorbing a deformation of the control member during the axial movement of the control member so that it is possible to prevent, if not avoid, mechanical wear on the control member and to reduce the No.sub.x concentration as well as obtain a highly reliable operation of the gas turbine combustor.

摘要： A turbine blade of a low blade profile loss with a crossing point of an inlet angle .alpha..sub.1 an outlet angle .alpha..sub.2 being located in a position in which a distance between a crossing point of the outlet end of the blade is greater than one-half of the blade width L.sub.ax, with the inlet angle .alpha..sub.1 being in the range of 35.degree.-40.degree. and the outlet angle .alpha..sub.2 being in the range of 25.degree.-28.degree.. A ratio of a narrowest width S.sub.2 of the flow channel at the blade outlet end to a narrowest width S.sub.1 of a flow channel defined between a backside of the blade in an area of the crossing point and a front side of adjacent blade lies in the range of 0.81-0.96. A ratio of a distance L.sub.ax to a blade width L.sub.ax is in the range of 0.5-0.54, with a ratio of a distance L.sub.m from an outlet end of the blade to the blade width L.sub.ax being in a range of 0.75-0.89. A ratio of a distance from the maximum projecting point to a line connecting to the outlet end of adjacent blades is in a range of 0.6-0.66. By virtue of the blade profile, the flow velocity differential between the fluid flowing along the front side of the blade and the fluid flowing along the backside of the blade can thereby be reduced.
