摘要： A variable clearance packing ring includes a plurality of circumferentially extending segments disposed in a generally dovetail-shaped slot in the stationary component of a machine having a rotor rotatable about an axis, the packing ring including an arcuate seal face in opposition to the rotor and axially extending flanges within the dovetail slot. Pins project axially from opposite sides of the stationary component for location between the flanges and sealing faces of the segments. A centering ring is mounted on the pins for each segment and has a coefficient of thermal expansion greater than the coefficient of thermal expansion of the segment. The centering rings engage the flanges of the segments at a first location, maintaining the segment seal face in a first clearance position relative to the rotor and engage the flanges at a second location in response to relative thermal expansion of the segment and the centering rings, enabling the segment to be displaced radially inwardly under the bias of a spring to locate the seal face in a second clearance position about the rotor radially inwardly of the first clearance position.

摘要： A brush seal is comprised of arcuate seal segments having ends cut in a radial direction with bristles "canted" at an approximate 45.degree. angle relative to radii of the segments, leaving triangular regions adjacent one end of each segment void of bristles at the junction of the segments. The brush seals are retrofit into conventional labyrinth seals with the backing plate for the bristles comprising a labyrinth tooth profile extending fully 360.degree. about the seal, including those areas where bristles are not present or only in the areas where bristles are not present. A support is provided at the juncture of the segments and to which support proximal ends of additional bristles are secured to project at an approximate 45.degree. angle relative to the segments at their juncture. Those additional bristles fill in the triangular region void of bristles when the support is secured to the end of the segment having the void whereby a full 360.degree. array of sealing bristles are provided.
摘要翻译：电刷密封件包括弧形密封段，其具有在径向方向上切割的端部，其中刷毛“倾斜”相对于段的半径为大约45°角，留下三角形区域邻近每个段的一端，细分。刷子密封件被改造成传统的迷宫式密封件，其中用于刷毛的背板包括围绕密封件完全360度延伸的迷宫齿廓，包括不存在刷毛的区域，或仅在不存在刷毛的区域中。在节段的接合部处设置有支撑件，并且附加刷毛的近端的支撑件被固定成在其接合处相对于片段以大约45度的角度突出。当支撑件固定到具有空隙的段的端部时，这些额外的刷毛填充没有刷毛的三角形区域，从而提供完整的360°密封刷毛阵列。

摘要： A fuel nozzle centering assembly and method employ bodies of a substantially wearable and sacrificial material mounted to an outer periphery of a tip of a burner fuel nozzle for a gas turbine combustor. The tip of the fuel nozzle extends through an opening of an annular collar attached to a liner of a main combustion chamber of the gas turbine combustor and an outer periphery of the tip is disposed radially inwardly from the annular collar such that the bodies of sacrificial material are disposed between the outer periphery of the fuel nozzle tip and the annular collar of the liner and space the fuel nozzle tip from the liner collar. The bodies of material prevent the fuel nozzle tip from contacting the liner collar during assembling of the fuel nozzle into the liner. The bodies wear away substantially upon initial operation of the combustor such that the bodies will reduce contact with the liner collar during further operation of the combustor and the fuel nozzle tip will remain spaced from and out of contact with the liner collar during operation of the combustor.
摘要翻译：燃料喷嘴中心组件和方法采用安装在用于燃气轮机燃烧器的燃烧器燃料喷嘴的末端的外周的基本上可穿戴和牺牲材料的主体。燃料喷嘴的尖端延伸穿过连接到燃气轮机燃烧器的主燃烧室的衬套的环形轴环的开口，并且尖端的外周从环形轴环径向向内设置，使得牺牲材料体设置在燃料喷嘴头的外周边和衬套的环形套环之间，并且使燃料喷嘴尖端与衬套相交。在将燃料喷嘴组装到衬套中期间，材料体防止燃料喷嘴尖端接触衬套。在燃烧器的初始操作时，物体基本上磨损，使得在燃烧器的进一步操作期间，主体将减少与衬套的接触，并且在燃烧器的操作期间燃料喷嘴头将保持与衬套的间隔开和脱离接触。

摘要： The air inlet to the compressor of a gas turbine is supplied with liquid nitrogen for cooling the ambient inlet air. The heated nitrogen converts to gaseous nitrogen and is supplied to either the combustor to lower the flame temperature and hence reduce NO.sub.x formations within the combustor or the turbine section to increase mass flow and hence increase power output, or both. Liquid nitrogen is also supplied in heat exchange relation with the cooling system of a generator driven by the turbine section. The operating temperature of the generator is thus lowered, thereby increasing its capacity and power. The nitrogen from the heat exchanger of the generator cooling system converts to gaseous nitrogen and is supplied to the combustor for lowered NO.sub.x emissions or to the turbine for improved mass flow, or both.
