Modeling and simulation of the pioneer 1MW solar thermal central receiver system in China

Off-design performance of concentrated solar heat and coal double-source boiler power generation with thermocline energy storage

“…However, it can be also found that when Re number is further decreasedto 0.1, the thickness of 24 thermocline increases much more as well. The reason is that despite the conductivity of molten salt keeping nearly constant, the convective heat transfer has been weakened too much because of the slowed speed, shown in Fig.…”

“…For the solar power tower plant, the north heliostat field is made of thousands of heliostats while the corresponding receiver isin the shape of cavity [24]. The optical efficiency of the heliostat field,f op , is divided into five parts: the cosine efficiency,f cos , the blocking and shading efficiency,f sb , the atmosphere attenuation efficiency,f att , the interception efficiency f itp , and the heliostat reflectivity f ref , which can be calculated by the specific algorithm [17],…”

Mathematical Modeling of a developed Central Receiver Based on Evacuated Solar Tubes

“…Another research in modeling and simulation of 1 MW DAHAN solar thermal power tower plant is done for the thermal plant integrated system by Ershu Xu et al [12]. And Zhihao Yao et al [13] present a modeling and simulation of the plant central receiver system. The heliostat field layout design HFLD software is used to calculate the performance of the plant, and TRNSYS plant model is developed for the plant simulation…”

Numerical simulation of solar radiation transmission process for the solar tower power plant: From the heliostat field to the pressurized volumetric receiver

“…However, few studies about the solar radiation transmission process from the heliostat field to the high working temperature pressurized volumetric receiver have been reported in literature [19][20]. So in this work, to reveal the complex photon-thermal conversion mechanism and to obtain the collection characteristic, M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT 3 tower plant are chosen as the physical model [8,[21][22], the in-house MCRT code is applied to simulate the radiation propagation process, and the non-uniform grid system is used for the statistic distribution of absorbing energy. The optical efficiency of the heliostat field and local heat flux distribution within the SiC absorber are calculated based on the above model and then the influences of time and date, receiver mounting height and heliostats tracking error on the radiation transmission and absorption process are investigated.…”
