Definitions

  • the present invention relates to solar thermal power plants having a receiver surface heated by reflected radiation from the sun, wherein said receiver surface comprises a plurality of identical volumetric receiver bodies each having an inlet and an outlet, through which an energy-carrying fluid medium such as air, is passed and heated to such temperatures that it is capable to generate power or process steam. More particular the invention relates to a hybrid volumetric receiver unit (VRU) for use in such solar power plants.
  • VRU volumetric receiver unit
  • the basic ceramic VRU has been tested in the confidential project HitRec and further in the SolAir project sponsored by the European Commission and proven durable in the period from late 1990ties.
  • Solar power plants are currently used for the conversion of short wave electromagnetic radiation from the sun into electricity.
  • Several technologies may be used in this conversion process.
  • One of these technologies comprises constantly adjustable mirrors, which reflect radiation from the sun and by continuous adjustments concentrate the radiation onto a receiver or absorber surface, which is thus heated.
  • Flowing a liquid or gaseous heat-collecting medium, such as water, molten salt, sodium, a gas or air, against or through the receiver surface cools it and heats the heat-collecting medium.
  • the heat-collecting medium may be passed through a heat exchange converter to generate steam, which is passed through a steam engine or turbine connected with an electric generator to produce electricity.
  • the heat-collecting medium which is cooled by this process, may be re-circulated in order to maximise the energy efficiency of the system.
  • the receiver surface which is heated by the reflected sun radiation, must be cooled all the time in order to avoid melting or evaporation of the construction material(s). Besides, very high temperature stable materials are needed for the construction of the receiver surface and its support.
  • Porous solids like extruded monoliths with parallel channels and thin walls made from various oxide and non-oxide ceramics, ceramic foams and metal structures have the objective to act as open volumetric receivers in concentrated solar radiation power plants.
  • ambient air flows through the volumetric receivers, which is heated by the concentrated solar radiation.
  • a heat exchanger then transfers the energy in a conventional steam turbine process.
  • high absorptivity in the visible and near infrared range has to be combined with a high porosity to create large surfaces for convective heat transfer from the solid absorber to the fluid, which may be air.
  • Especially high performance absorbers tend to be sensitive to inhomogeneous flux distributions, which may cause local overheating of the material. In various tests with specific kinds of materials flow instabilities occurred, which partly lead to hot spots and a damaging of the receiver.
  • the wind at relatively high speed around the solar thermal power plant top has such an influence that smaller channels of the honeycomb are better than larger cells which increase the short wave to long wave conversion efficiency.
  • the wind changes the air speed down through the individual channels of the volumetric receiver unit by changing the pressure drop over that specific channel.
  • Lower air speed in the specific channel means lower energy passing out through the supporting funnel cup outlet.
  • the higher front face temperature reflects more energy to the environment.
  • the present invention overcomes the above drawbacks and achieves both high efficiencies and a safe operation with an optimised combination of geometrical as well as thermal conductivity and heat transfer parameters. Summary of the invention
  • the object of the present invention is to provide a high thermal efficiency integrated volumetric receiver unit (VRU), module or assembly, preferably manufactured from SiC based materials, comprising a ceramic volumetric receiver body and a support member for use in a solar thermal power plant at temperatures of about 1000 - 1200 °C.
  • VRU high thermal efficiency integrated volumetric receiver unit
  • the integrated volumetric receiver unit is manufactured from metal or a combination of metal and ceramics.
  • volumetric receiver body or absorber monolith has an efficiency improving porous material mounted in front of the porous receiver body or monolith which acts as a support member therefore so as to constitute an even more efficient volumetric receiver unit (VRU).
  • VRU volumetric receiver unit
  • the present invention is depending on a basic VRU as a support for a layer of more porous material mounted in front of the VRU.
  • the front of the volumetric receiver unit faces towards the reflective mirrors concentrating the solar flux thereon and its performance is further optimised for higher short wave conversion efficiency, when supplied with a flow stabilising and/or insulating layer of highly porous material such as fibres formed into a fabric, felt or mat with a thickness of less than 10 mm consisting of fibres being 5 to 250 ⁇ m thick.
  • a slice of a higher cell density monolith or a super high pore density foam or combinations thereof can be used.
  • a front material comprising a high specific surface, excellent absorption capacity and high porosity (e.g. Ceramat from Schott Glaswerke) to achieve volumetric absorption of the concentrated solar radiation has been combined with a material of excellent thermal conductivity properties and a quadratic pressure loss characteristic (e.g. SiC or SiSiC honeycomb multi-cell supports such as supplied by HelioTech in Denmark) of 85 mm in diameter as shown in Fig 1.
  • the SiC fibre mesh (Schott Ceramat) was originally developed for pre-mixed natural gas surface burners. It consists of silicon carbide fibres of 25 ⁇ m diameter CVD glued together to form a layer of 3,5 mm thickness. The fibres are oriented in directions perpendicular to the direction of the airflow, beneficial for radial heat transport and good heat transfer properties.
  • An inclined or rounded design of the VRU upper edges and/or corners allows a higher return air/re-circulation air ratio thus further increasing the thermal efficiency of the VRU, the re-circulation air being of a higher temperature than ambient air.
  • an insulation layer which at the same time is permeable to air and has a high thermal conductivity, increases the total energy efficiency of the system.

Abstract

L'invention concerne une unité ou un ensemble de réception volumétrique hybride destiné(e) à être utilisé(e) dans des centrales solaires chauffées par des rayons concentrés provenant du soleil, ladite unité ou ledit ensemble comprenant : un corps de récepteur volumétrique présentant une entrée et une sortie entre lesquelles est disposée une partie intérieure perméable à un fluide, par laquelle passe un fluide porteur d'énergie tel que de l'air ; ainsi qu'une matière mince très poreuse fixée au côté entrée du corps de récepteur volumétrique, qui est exposé directement aux rayons du soleil. Si l'on compare avec un ensemble récepteur volumétrique classique (c'est-à-dire ne possédant pas ledit matériau poreux), un système de centrale thermique pourvu de l'ensemble selon l'invention peut atteindre des températures de sortie d'air plus élevées, comprises dans la plage 600-850° C, et un rendement thermique supérieur à 95 %. Cela se traduit directement dans la réalité par le fait que l'on peut utiliser un champ d'héliostats plus petit, ce qui influe de façon très positive sur les coûts d'investissement qui sont ainsi réduits.
