Abstract:
PROBLEM TO BE SOLVED: To modify turbine blades 10 of a gas turbine to surely join both shell elements. SOLUTION: In the turbine blades 10 of the gas turbine provided with an attachment part/blade base part 14, and having a blade profile part 16 with a blade profile part tip 36 including both side shell elements 28, 30 positioned with opposing each other adjoin the attachment part/blade base part 14, and having the shell elements 28, 30 mutually joined as a blade back side wall 18 or a blade face side wall 20 respectively, the both shell elements 28, 30 are protected from being mutually peeled off by meshing engagement in a region of the blade profile tip 36.

Abstract:
PROBLEM TO BE SOLVED: To very easily adapt a stationary vane 14 to an individual service condition at particularly inexpensive apparatus cost and spare part replenishing cost, in the stationary vane 14 in a gas turbine 1 having a vane body 28 of a single body structure composed of a vane leg 18, a shroud 26 and a vane-shaped part 24 extending between its both. SOLUTION: This gas turbine is provided by joining a flow guide body 30 having a front guide vane 32 places at the front end in the vane-shaped part 24 in the flowing direction of a working medium M of the gas turbine 1 to the vane body 28. At least two stationary vanes 14 of a stationary vane cascade have the flow guide body 30 having different front guide vanes 32. This flow guide body 30 is made of a heat resistant material larger than the vane body 28. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To cool a blade pedestal of a turbine blade and/or obtain, at an inexpensive manufacturing cost, a cooling function of the blade pedestal in a turbine blade (10) in a turbine in a thermal electric power station which is equipped with a blade pedestal (16) for partially bounding a working medium flow channel in the turbine and in which the blade pedestal (16) includes at least one coolant passage (20) that extends inside the blade pedestal and is used for guiding the coolant. SOLUTION: At least one coolant passage (20) communicates with an outside of the blade pedestal (16) in at least two connection openings (22). The turbine blade (10) includes at least one accessory (24, 26) equipped with a coupling passage (28) attachable to the blade pedestal (16). Further, the coupling passage (28) is designed to be connected with the connection openings (22) so as to be guidable for a flow. COPYRIGHT: (C)2008,JPO&INPIT
Abstract:
Plastics do not have the mechanical or erosive properties required for specific areas of application. The inventive plastic comprising powder particles (7) improves the properties of said plastic in relation to mechanical characteristics and erosive properties for components, coatings and sealing systems.
Abstract:
The guide vane (14) has a vane base (28) designed as a single piece and including a vane root (18), a cover plate (26) and a vane blade (24) extending between the vane root and the cover plate. A flow guide body (30) located on the vane base is attached to a pre-guiding blade (32) which is connected upstream of the vane blade with respect to a flow direction of a working fluid of a gas turbine. The flow guide body is made of a material temperature-firm compared to the vane base.

Procedimiento para detectar suciedad en componentes de turbina de una turbina (3), caracterizado porque se calcula al menos un parámetro de vibración actual de al menos un componente de turbina.
Abstract:
The blade has a platform (16) for defining a flow channel in a turbine, where the platform has a coolant channel (20), which extends in the platform and guides the coolant. The coolant channel leads to two connection openings of the platform. An auxiliary component (24,26) is fastened at the platform, and has a connecting channel (28), which connects the openings with each other in a fluid-conductive manner. The platform extends transverse to a longitudinal extension of the blade along a main defining surface (30), and has front surfaces, which are arranged transverse to the extension.
Abstract:
The blade segment (2) has a set of profiled blades (6) arranged on a platform (8). A set of securing units (14) securing the guide blade segment to an associated guide blade support are arranged on a side of the platform, which is oriented away from the blades. A section of one of the securing units is a separately produced component, which is rigidly connected to the platform or to an additional section of the securing unit. An independent claim is also included for a method for manufacturing of a guide blade segment.
