Technical feasibility analysis of a linear particle solar receiver

Solid particle solar receivers in the next‐generation concentrated solar power plant

“…G omez-Hern andez et al 39,40 introduced the linear fluidized bed SPSR placed on the ground, the SPSR is composed of multiple fluidized bed units with the HTF moving horizontally, as presented in Figure 5C. The linear solar irradiance flux is ensured by Fresnel heliostats and a secondary concentrator, two highly transmissive glass covers are placed over the fluidized beds, and the heat loss can be reduced due to the vacuum condition between the glass covers.…”

“…29 The SPSR technologies have been further developed and new designs have emerged. [30][31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] Moreover, the previous review papers mainly focused on the structural designs and thermal performance of the various SPSRs, other related aspects such as solid particle selections, receiver system structure optimization, particle flow characteristics, and heat transfer characteristics are not discussed in-depth. As a result, this article provides a more comprehensive review of various SPSR technologies and highlights the technical drawbacks, the large-scale development prospects, and the potential optimization strategies of the various SPSR designs through the comparative analysis of multiple parameters.…”

“…However, due to the demand for higher solar‐to‐electricity efficiency and lower LCOE of CSP plants, a number of countries have carried out demonstration projects on solid particulate‐based CSP plants in recent years 29 . The SPSR technologies have been further developed and new designs have emerged 30–49 . Moreover, the previous review papers mainly focused on the structural designs and thermal performance of the various SPSRs, other related aspects such as solid particle selections, receiver system structure optimization, particle flow characteristics, and heat transfer characteristics are not discussed in‐depth.…”

Fluidized Beds for Concentrated Solar Thermal Technologies—A Review

“…The stepwise co-current horizontal movement of gas and solids enables the absorption of the solar radiation along the linear receiver. The receiver thermal performance coupled with the beam-down linear Fresnel reflector has been characterized by Gómez-Hernández et al (2020).…”
