A steam-turbine unit has a steam turbine and an option for cooling the steam turbine by forced cooling, wherein cooling air is drawn through the steam turbine via a suction device and a drainage line of the live-steam valve is used as the access option.

Method for cooling down a steam turbine

A method is provided for carrying out a sound test for detecting and/or analyzing material faults and/or mounting faults of at least one component, in which the component is excited, by striking, to experience vibrations which generate soundwaves, after which the generated soundwaves are detected and conclusions are drawn about material faults and/or mounting faults on the basis of the detected soundwaves, wherein the striking of the component and the detection of the vibrations are carried out using an endoscope device. In addition, embodiments of the present invention relates to an endoscope device which is configured to carry out the method.

A module for a thermal power plant for condensing expelled vapors and cooling turbine effluent from the drained turbine includes a first unit designed to condense expelled vapors as well as a second unit designed to cool the turbine effluent, condensate from the first unit being transferable to the second unit.

Module for condensing expelled vapors and for cooling turbine effluent

A method for controlling a cooling process of turbine components of a steam turbine shaft, wherein an air flow mixed with a water mist is used to cool the turbine components during a mist cooling phase (P) is provided. The mist cooling phase (P) is preceded by an air cooling phase (P), during which an air flow is used to cool the turbine components. A constant temporal temperature gradient is specified for the cooling process, wherein the air flow density is adjusted by the valve position of a controllable regulating valve and a switch is made from the air cooling phase (P) to the mist cooling phase (P) if the maximum air flow density is reached and in particular if the regulating valve is fully open.

A method for regulating a steam bypass valve is provided. The bypass valve is arranged in a steam line and the steam line includes a device for spraying water. The equation, is used to determine when to close the steam bypass valve. The steam bypass value is closed when tis smaller than a value &#x394;t. An actual volume of water {dot over (m)}, a desired volume of water {dot over (m)}and a maximum water-volume deficiency FBmax are used in the equation.
