Definitions
- Thermal power plant in particular solar thermal power plants
- the invention relates to a thermal power plant, in particular a solar thermal power plant, comprising a gas turbine device in which circulates a circulating through thermal energy heated medium for generating electrical energy through a turbine and subsequently into a cooled by a cooling condenser for liquefying the medium becomes.
- Power plants where heat energy is converted into electrical energy, are widely known. It is customary to evaporate a medium by the heat energy, after which the vaporized medium operates a turbine, whereby electrical energy is generated. Subsequently, the steam is re-liquefied in a condenser cooled by a cooler and returned to the evaporator. It is customary to cool the condenser in particular by a water cooling, so provide a water-filled cooling tower or to remove the water from a natural source in the area.
- Evaporator heats the medium.
- various embodiments are known, for example, in a field erected mirror reflect sunlight to a collection tower, which can then be heated locally to very high temperatures.
- Other possibilities are parabolic mirrors or, in particular, so-called parabolic troughs, which focus and collect sunlight at a point or along a route.
- parabolic troughs it has also been to use cheaper, flat mirrors, which are arranged in different orientations below the elongated heat collecting device.
- the invention is therefore the object of a power plant to design so that no natural water resources are needed or no loss of water occurs.
- the cooling device is designed as a solar-powered cooling device with a closed coolant circuit.
- the power plant is particularly advantageous solar thermal power plant, which is already used in regions where there is a long sunshine duration.
- thermoacoustic chiller or a Stirling chiller, in particular a plurality of Stirling chillers, or an absorption chiller, in particular a diffusion absorption chiller, wherein the absorption chiller is preferred according to the invention.
- thermoacoustic chiller The principle of the thermoacoustic chiller is a relatively new development in which the acoustic energy of a standing sound wave in a suitable resonator is used for heat transport.
- heat or cold is transported via the periodic pressure fluctuations experienced by a gas packet in a standing longitudinal sound wave.
- the sound wave can be generated electromechanically via a loudspeaker, for example, and pump heat against a temperature gradient along a storable medium, the so-called stack. Along the stack, a temperature gradient builds up. Incidental heat or cold can be emitted on both sides of the stack with heat exchangers. be coupled.
- Such a thermoacoustic chiller is particularly advantageous since its only moving part is the sound wave generator.
- Stirling chiller Another variant of a suitable chiller is the Stirling chiller.
- Such machines are well known and based on the Stirling process. However, in order to obtain the required cooling capacity, it may be necessary to use several Stirling refrigerators as a cooling device.
- an absorption chiller is preferably used.
- the compression takes place by means of a temperature-influenced solution of the refrigerant in a solvent.
- a temperature-influenced solution of the refrigerant in a solvent This is also referred to as a "thermal compressor.”
- An absorption chiller also has a solvent circuit. The two components, solvents and refrigerants, are often referred to collectively as work equipment, provided that the refrigerant is completely soluble in the solvent.
- the working fluids are first separated from each other in a so-called expeller by heating the solution in which the vapor of the refrigerant is freed from the coevaporated solvent residues by means of a liquid separator.
- the refrigerant is liquefied in order to be vaporized in the evaporator while absorbing the ambient heat n, whereby the efficiency arises.
- the refrigerant vapor is then directed into the absorber, where again a solution is formed.
- the solvent is introduced after the separation of the refrigerant after it has been relaxed by a valve to the absorber pressure and cooled.
- the solvent cycle is what ultimately serves as a "thermal denser "as it takes over the corresponding tasks of the compressor of the compression refrigeration machine.
- a variant of the absorption chiller is the so-called diffusion absorption chiller, in which the pressure change is realized as a partial pressure change, so that with the solvent pump and the last mechanically moving component is eliminated.
- a third component is required for the working fluid, namely an inert gas. Diffusion absorption refrigerators thus only require the supply of solar heat.
- the operation of the cooling device can be provided directly by the heat of the sun or by means of a heat of the sun transmitting thermal oil. These are the two basically known methods that are also used in solar thermal power plants.
- the heat of the sun can be used immediately or only be brought to the place of use by a thermal oil.
- the single figure shows a schematic diagram of a solar thermal power plant according to the present invention.
- the figure shows an embodiment of a solar thermal power plant 1 according to the present invention. It comprises first, the power plant operation serving solar panels 2, which are formed in the present case as parabolic troughs. By means of the solar heat thus centered in a central region above the parabolic troughs, a medium circulating in a circuit 3 is heated and vaporized directly, with the resulting steam being converted into electrical energy in a turbine 4. In a condenser 5, the medium is liquefied again, wherein the condenser is cooled by a solar-powered cooling device 6. The liquefied medium is then evaporated again, so that the circuit 3 is closed. It should be noted that this is of course only a schematic of the most important components; The principle of a thermal power plant is well known and need not be explained in detail here.
- the cooling device 6 comprises a closed coolant circuit 7, in which water circulates as coolant.
- chiller 8 which is designed here as an absorption chiller, more precisely as a diffusion absorption chiller.
- the heat required for this purpose is again solar heat, which is collected via solar panels 9.
- chiller 8 The function of the chiller 8 is well known and need not be discussed in detail here.
- the chiller 8 may also be a Stirling chiller or a thermo-acoustic chiller.
- the heat of the solar collectors 9 can be used directly as a heat source for the refrigeration machine 8. be used or transferred via a thermal oil there.
