摘要： A turbine (100) of a turbine installation, especially a steam turbine of a steam turbine installation, includes at least one radial or diagonal turbine stage (120) with radial or diagonal inflow and axial outflow, and also at least one axial turbine stage (121-125) with axial inflow and axial outflow. The at least one radial or diagonal turbine stage (120) forms the first stage of the turbine (100) and the at least one axial turbine stage (121-125) is arranged downstream of the radial or diagonal turbine stage (121) as an additional stage of the turbine. The at least one radial or diagonal turbine stage (120) has a higher temperature resistance than the at least one axial turbine stage (121-125). The turbine (100) makes it possible to significantly increase the process temperature of the steam turbine installation, wherein measures for increasing the temperature resistance need only to be adopted for components of the radial or diagonal turbine stage (120).

摘要： A turbomachine has, on its inner casing (5) and on its shaft, recesses into which shrouds of rotor blades and/or of guide vanes (2a) protrude. The recesses are configured with wave-shaped contouring arrangements (10), which extend over their periphery. The contouring (10) extends over axially extending regions of the recess and consists of periodic elevations and depressions (14, 15) in the radial direction. They can also be effected on the radially extending regions of the recess and on the shrouds. The undulation-shaped contouring arrangements are used to counteract existing pressure fields and to reduce performance losses due to mixing processes between the leakage flow and the main flow.

摘要： To reduce the number of stages of a turbine and, associated therewith, the overall length and the costs, blading having high stage-specific enthalpy transfer is to be used. In this case, the disadvantages of conventional highly loaded blading, such as increased secondary flow losses due to blades of large chord length and comparatively small height and the design of the turbine in the complicated chamber type of construction, are to be avoided. Resulting from these requirements is a highly loaded slim blade type of construction having considerable deflection. A turbine having blading according to the invention is characterized by a loading parameter RBL, which in the HRBL blading according to the invention, in contrast to conventional types of construction, is greater than 1.

摘要： A blade (31) of a turbomachine, especially of a steam turbine, is characterized in that the chord length (sm) in the middle region of the blade airfoil (34) is shorter than the chord lengths (s0, s1) in the tip-side region (35) or root-side region (33) of the blade airfoil. As a result of this, a distribution of the Zweifel parameter over the longitudinal extent of the blade airfoil is achieved which minimizes the losses of a blade cascade of the proposed blades.

摘要： A steam turbine (10), especially in the form of a double-flow low-pressure steam turbine, includes a rotor (11) which is rotatably mounted around an axis (21) and which is concentrically enclosed with a spacing by an inner casing (13), forming annular steam passages (28, 29), and which has a multiplicity of rotor blades (12) which project into the steam passages (28, 29), wherein the inner casing (13) supports a multiplicity of stator blades (12) which project into the steam passages (28, 29) and which, for feeding steam to the steam passages (28, 29), has an inlet duct (15) which is directed around the axis (21) and tapers in the flow cross section. With such a steam turbine, the production is simplified by the inner casing (13) being formed as a welded construction, in which blade carriers (14), which delimit the steam passages (28, 29) and are produced as cast parts, are welded to additional forged or rolled steel elements (20) for fastening the stator blades (12′).
