    摘要： The invention relates to a steam power plant (1) in which a working fluid (2) circulates in a circuit, wherein a regenerative intermediate superheater (30) is provided which preferably intermediately superheats the entire flow of the working fluid (2) before it enters into a low-pressure turbine (11) and which is heated by means of steam extractions from the relief path (8) situated upstream. The steam flows which heat the intermediate superheater (30) are preferably utilized for feed fluid pre-heating (4). The intermediate superheater (30) is embodied as multi-stage regenerative intermediate superheater (30). This leads to increased efficiencies and reduced erosion on the low-pressure blades.

    摘要： Power generation plant and method of generating electric energy from recovered heat during an industrial process that uses steam as a means of transferring energy. The method comprises generating a first saturated steam in a first heat exchanger heated by a first source of recovered heat, feeding the first saturated steam into a first steam turbine generator where the first steam turbine generator outputs exhaust steam, removing moisture from the exhaust steam with a moisture separator, superheating the moisture reduced exhaust steam from a main heat exchanger with a heat source, and feeding the superheated exhaust steam into a second steam turbine generator. The power generation plant comprises a first source of saturated steam, a first steam turbine generator, a moisture separator, a second source of saturated steam, a heat exchanger and a second steam turbine generator.

    摘要： A combine cycle power plant is presented. The combine cycle power plant includes a gas turbine, a heat recovery steam generator, a main steam turbine and a supercritical steam turbine. The supercritical steam turbine may be operated as a separate steam turbine that may be not a single steam turboset with the main steam turbine. The supercritical steam turbine receives supercritical steam generated in the heat recovery steam generator to produce power output. Exiting steam from the supercritical steam turbine may be routed to the main steam turbine. The supercritical steam turbine may be operated at a rotational speed that is higher than a grid frequency. The rotational speed of the supercritical steam turbine may be reduced to the grid frequency via a gearbox.

    摘要： A process for energy storage comprises carrying out a cyclic thermodynamic transformation (CTT) wherein, in a charge phase, a condensation of a working fluid (WF) is executed by means of heat absorption by a heat carrier (TV) in order to store the working fluid (WF) in the liquid or supercritical phase; wherein, in a discharge phase, an evaporation of the working fluid (WF) is executed starting from the liquid or supercritical phase and by transfer of heat from the heat carrier (TV); wherein provision is made for actively adjusting at least one parameter of the working fluid (WF) related to the condensation and/or to the evaporation, in order to control at least one temperature of the heat carrier (TV) and uncouple it from the ambient temperature (Tamb) without the aid of systems outside the cyclic thermodynamic transformation (CTT).
