Hydrodynamics of Dense Fluidized Beds for Application in Concentrated Solar Energy Conversion

摘要: In the frame of call for projects European Commission which aims to find alternative HTF in order extend working temperature and decrease environmental impact standard Heat Transfer Fluid (HTF) used concentrating solar power(CSP) plants, we proposed use Dense Particle Suspensions -DPS- fluidized with air (approximately 50% solid) tubes as new HTF. DPS will enable operating over 1 000°C corresponds sintering temperatures solid against 560°C most efficient molten salts, thus increasing plant efficiency decreasing cost per kWh produced, have no lower limitation are riskless. A cold mockup receiver using has been built preliminary study concept. The operation shown possibility ensure a regular adaptable upward flow range 10 65 kg/h tube. This paper compares experimental results running predictions multi-fluid approach 3D numerical code.
