Abstract: A steam power plant including a number of partial turbines is provided. Each partial turbine is permeated by steam, an overflow line disposed between a first partial turbine and a second partial turbine and an intermediate superheater in the overflow line. A bleeder line for extracting steam is thereby fluidically connected to the first partial turbine after the expansion stage, prior to the intermediate superheater. An expansion device is further provided, into which the bleeder line opens, and a consumer is connected via a process steam line of the expansion device.

Abstract: A solar-thermal power plant is provided. The solar-thermal power plant includes a working fluid circuit, a solar steam generator based on direct evaporation and a steam turbine for relieving the working fluid on a relief path while the working fluid supplies technical work. The solar-thermal power plant also includes at least one intermediate superheater, which can be heated using the working fluid. The working fluid may be removed from the circuit upstream of the intermediate superheater and superheated using the working fluid thereof, which can be fed downstream of the heating removal using the relief path. A method for operating a solar-thermal power plant is also provided.

Abstract: The invention relates to an inventive steam power plant comprising at least one steam turbine and a steam generator. According to the invention, a firing device is located downstream of the steam generator and upstream of the steam turbine and/or downstream of a first turbine phase and upstream of a second turbine phase of the stream turbine in the direction of the stream flow and the steam flow can be heated in a combustion chamber of the firing device by being mixed with a heating gas that can be generated in the combustion chamber.

Abstract: An inventive steam power plant comprises at least one steam turbine and a steam generator, whereby a combustion chamber, in the direction of the flow of steam, is mounted after a first turbine stage and before a second turbine stage of the steam turbine, and the flow of steam inside a combustion chamber can be heated by mixing it with a hot gas that can be produced inside said combustion chamber.

Abstract: The invention relates to a method for operating a steam power installation, whereby steam produced in a boiler is condensed in a condenser after passing through at least one turbine, and the condensate obtained is preheated and redirected back to the boiler as boiler feed-water. In order to preheat the condensate, said condensate is split into a first partial current and a second partial current. Only the first partial current is preheated and the second partial current is then mixed with the preheated first partial current. The power of the turbine can thus be increased as required, up to the boiler reserve of the steam power installation.
