A dissimilar metal connection arrangement comprising a dissimilar metal connection between a first member made of a first metal and having a first end, and a second member made of a second metal different from said first metal with regard to its metallurgical behavior, and having a second end, wherein the first end of the first member is fixedly connected to the second end of the second member. An increased lifetime of the connection is achieved by arranging a heating means at said dissimilar metal connection for controlled heating of said dissimilar metal connection.

Dissimilar metal connection and method for operating such a dissimilar metal connection

A steam condenser ( ) which, relative to a steam turbine ( ), is arranged at equal ground level and into which turbine steam flows in the horizontal direction through the condenser neck ( ) has two or more modules ( ) in which the steam condenses on cooling tubes ( ). The modules ( ) are, in accordance with the invention, separated by a defined intermediate space ( ). The central, mutually facing module walls ( ) are supported and connected to one another by connecting parts ( ). This arrangement contributes to a defined stress distribution in the central module walls ( ). In a particular embodiment, bypass conduits ( ), which lead the steam from the boiler directly into the steam condenser ( ) while bypassing the turbine ( ), are arranged in the intermediate space ( ). For this purpose, the bypass conduits ( ) lead to a steam introduction appliance ( ), which is arranged at the condenser neck ( ) at the level of the intermediate space ( ). Because of this positioning, the flow of the turbine steam ( ) into the steam condenser ( ) is not hindered.
