Thermal power process

A thermal power process comprising:

• firstly effecting a first thermodynamic change of state of a process fluid from a first thermodynamic state to a second thermodynamic state, including compressing the process fluid;
• secondly effecting a second thermodynamic change of state of the process fluid from the second thermodynamic state to a third thermodynamic state including supplying heat to the compressed process fluid, with the heat being supplied indirectly by a heat exchange process;
• thirdly effecting a third thermodynamic chance of state of the process fluid from the third thermodynamic state to a fourth thermodynamic state, including expanding the process fluid;
• fourthly effecting a fourth thermodynamic change of state of the process fluid from the fourth thermodynamic state to the first thermodynamic state, including dissipating heat from the expanded process fluid in at least one heat sink;
• completely returning the process fluid to the compression process such that the process fluid is guided in a completely closed cycle;
• introducing an amount of steam into the process fluid;
• expanding said amount of steam together with the compressed process fluid;
• substantially condensing said steam in a first heat sink of said at least one heat sink;
• separating said condensed steam as condensate from the process fluid;
• evaporating said condensate;
• introducing the steam resulting from said evaporating into the process fluid;
• wherein said evaporating of the condensate occurs with heat dissipated from said first heat sink, wherein an amount of steam is generated with live steam pressure, and wherein said amount of steam is added to the completely compressed process fluid prior to said expanding;
• adding at least a fraction of the steam to the process fluid prior to providing heat;
• and
• providing heat to said steam fraction together with the process fluid.

A device useful for carrying out a thermal power process, the device comprising:

• at least one compression means for effecting a thermodynamic change of state from a first thermodynamic state to a second thermodynamic state;
• means for providing heat including a heat exchanger, though which heat exchanger the process fluid can flow on a secondary side, said means for providing heat arranged downstream from the at least one compression means;
• at least one expansion means arranged downstream from the means for providing heat;
• at least a first heat sink arranged downstream from the at least one expansion means;
• means for guiding process fluid from the at least first heat sink to the at least one compression means;
• a steam generator;
• means for introducing steam from the steam generator into the process fluid arranged downstream from the compression means and upstream from at least one of said at least one expansion means;
• means for separating resulting condensate from the process fluid;
• means for flowing the condensate to the steam generator;
• wherein the heat sink is substantially identical to the steam generator;
• wherein the steam generator is configured and arranged for receiving the process fluid on a primary side and flowing the process fluid therethrough;
• and
• means for introducing liquid drops into the process fluid that flows though the compression means.
