    摘要: A method of modifying a steam turbine to change from a first maximum thermal power of the steam generator to a second maximum thermal power of the steam generator. The method can include replacing, in the high-pressure module, at least one set of fixed blades sized for the first maximum thermal power by at least one set of fixed blades sized for the second maximum thermal power. The at least one set of moving blades are sized to operate at the first and second maximum thermal powers. The rotor and the at least one set of moving blades of the high-pressure module remain unchanged on changing from the first maximum thermal power to the second maximum thermal power.

    摘要: Systems and methods of detecting and correcting the undesirable operation of a turbine by monitoring one or more sensor devices, where each sensor device monitors one or more operating parameter values associated with various turbine components. If any of the sensor devices detects that a particular operating parameter associated with one or more turbine components is operating in a range of unacceptable risk, then corrective action is taken which may include opening and or closing one or more of the steam values associated with an inlet pipe until that particular operating parameter of the turbine is no longer operating in a range of unacceptable risk.

    摘要: In a gas turbine, the compressor load is reduced and the turbine load is increased for controlled bearing load reduction by forming a low-pressure chamber (8) that is shielded from the compressor air at the compressor (1) and a high-pressure chamber (9) that is supplied with compressor air at the turbine along the high-pressure shaft (2). The pressures can be controlled within specific limits. Controlled bearing load reduction allows high speeds and a long service life of the bearings.

    摘要: Disclosed is a high-pressure centrifugal blower, which comprises an impeller with a back plate and pressure leveling blades secured to the back side of that back plate. The blades extend from the periphery of the impeller over some distance radially inwards. In order to regulate the pressure control clearance between the blades and the back wall of the blower case, control members have been installed between the blades and the back wall of the case.
