摘要： A high pressure first stage turbine and seal assembly are described. In one embodiment, a high pressure turbine section is provided. The turbine section includes at least one stage, at least one rotor and a bucket assembly. The bucket assembly includes a bucket and an attachment fixture. The stage has a high root reaction during operation. An intermediate space is between the bucket assembly and a stationary component of the turbine section.

摘要： A unique finger dovetail pin configuration is provided to attach the buckets of a control stage of a turbine to the rotor wheel. More particularly, as an embodiment of the invention, a bore is provided through the center of the pin to form a hollow pin. The primary benefit of providing a hollow pin configuration is that a passage is defined for the axial flow of steam through the dovetail attachment. For a control stage bucket, this axial flow is desirable to minimize the leakage of steam from the space between the first stage nozzle and bucket, and to provide a source of cooling flow to the forward side of the turbine wheel. Another benefit of the hollow pin is to facilitate removal of the pins when servicing of the high pressure rotor is required.
摘要翻译： 提供独特的手指燕尾针构造以将涡轮机的控制级的桶附接到转子轮。 更具体地，作为本发明的实施例，通过销的中心提供孔以形成中空销。 提供空心销构造的主要益处是为通过燕尾榫附件的蒸汽的轴向流动定义通道。 对于控制级斗，这种轴向流是期望的，以最小化来自第一级喷嘴和铲斗之间的空间的蒸汽的泄漏，并且向涡轮机叶轮的前侧提供冷却流源。 空心销的另一个好处是当需要维修高压转子时便于拆卸销。

摘要： Solid particle erosion in a steam turbine is minimized by diverting through holes in appendages of outer rings of the diaphragms, a portion of the steam from the steam flow path thereby bypassing downstream rotating components. The hole through the first stage appendage lies in communication with a passage through a downstream outer ring of a following stage such that the diverted solid particle containing steam may be extracted from the steam flow path and passed to the feed water heater of the turbine. The hole in the second stage appendage diverts steam from between the first and second stages and about the second stage. Solid particle erosion in various regions, i.e., the trailing edge of the stator vanes, along the surfaces of the buckets and in the regions of the cover and its connection with the buckets as well as the sealing devices are thereby minimized.
