摘要： A turbine diaphragm assembly is described having an annulus of static blades, each static blade including at least an aerofoil and an outer platform; and an outer diaphragm ring or segments of a ring for holding the annulus of static blades; with confronting edges of the outer platforms and the ring are held by an interference fit when pushed in axial direction into contact with the interference fit designed to withstand the forces on the diaphragm during operation of the assembled turbine.

摘要： A diaphragm for an axial flow turbomachine, in which outer shrouds of adjacent fixed blades in a row of blades contact each other circumferentially to form a circumferentially continuous load path. Inner shrouds of the blades only contact each other on contact faces oriented to transmit loads in the radial and/or axial directions of the turbomachine.

摘要： A method for measuring deformation of a shaft by a device includes illuminating a pattern applied on the shaft before the deformation is applied; and detecting a first reference position by detecting the radiation reflected by the pattern, after the deformation is applied illuminating the pattern and detecting a second reference position by detecting the radiation reflected by the pattern. Based on the distance between the first and the second reference positions, the shaft circumferential deformation and/or torque is determined.

摘要： A turbine blade has a shroud, a blade portion and a T-section root portion configured to lock into a T-section channel in a turbine rotor adjacent like blades in a ring. The blade portion is pre-twisted so that mutual alignment of the edges of the root and the shroud portion along the axis of the turbine in the final assembled condition provides a torsional bias which maintains the shroud in frictional contact with its neighbours to resist relative radial movement. The root portions have generally flat-sided surfaces occupying opposed substantially parallel radial planes of the T-section, but have circumferential abutments in the form of lands projecting from each side of the root portion at the same radius. When the circumferential abutments are radially aligned in the final assembled position, angular separation between adjacent blades is greater, by an amount related to the combined thickness of the abutments, than when the abutments are radially staggered.

摘要： One turbine, e.g. a high pressure (HP) turbine, has a conventional diaphragm and disc structure with impulse turbine stages. A preceding or following turbine, e.g. an intermediate (IP) turbine, on a common axis and on the same steam path, has a rotor drum which carries an annular row of moving blades having root portions held within a slot in the periphery of the drum. A turbine casing surrounds the drum and carries a static blade assembly with an annular row of static blades which, together with the annular row of moving blades, constitutes a modified turbine stage. The static blade assembly has a radially inner static ring with a radially inner side confronting the periphery of the drum. A seal acts between the inner static ring and the rotor. The static blade assembly has an outer static ring which has a substantially greater thermal inertia and stiffness then the inner static ring and which is capable of sufficient sliding relative to the casing in a radial sense to accommodate relative thermal expansion and contraction of the outer static ring and the turbine casing.

摘要： A steam turbine is provided that is configured for post-modification for operation in a carbon capture mode. The turbine includes a turbine rotor, a turbine casing and a plurality of turbine stages. In an initial configuration of the turbine, the turbine rotor and turbine casing are each longer, by respective lengths, than is necessary to accommodate the plurality of turbine stages. The lengths are sufficient to accommodate at least one further turbine stage at an exit of the turbine during the post-modification, such that after modification, the turbine operates with an increased expansion ratio and an increased volumetric flow rate at the exit.
