Description

technical field

[0001] The invention relates to a plant, in particular a power plant, comprising a steam turbine and a bypass station for guiding a working medium for the steam turbine bypassing the steam turbine as required. Furthermore, the invention relates to a method for damping acoustic vibrations in a corresponding installation. Background technique

[0002] In power plants it is often necessary to take measures for reducing the sound emissions of the power plant in order not to exceed permissible limit values ​​for the sound emissions.

[0003] If, for example, steam turbines are used in the respective power plant, a bypass station is usually also provided in order to conduct the working medium for the steam turbine bypassing the steam turbine as required. A bypass station of this type usually includes a line by means of which the working medium is directed into the condenser without passing through the steam turbine. In this case, the working medium under pressure...

Embodiment Construction

[0022] In the embodiment described hereinafter, the facility 2 is part of a power plant for the production of electrical energy and comprises therefor a steam generator 4, a condenser 6, a steam turbine 8, a bypass station 10 and a piping system substantially constructed of pipes 12. The piping system connects the individual components mentioned above to one another and serves to conduct the working medium, here water and steam.

[0023] as in figure 1 As shown in , two possible paths through the piping system 12 are provided for water or steam, wherein in load operation the water steam is guided through the steam turbine 8 and in no-load operation the water steam is guided through Bypass station 10.

[0024] A very purposeful design variant of the bypass station 10 is in the figure 2 are shown according to the type of block diagram. The bypass station 10 is formed by a line 14 which is connected to the pipeline system 12 via a controllable bypass valve 16 . By correspond...
