Review of study on solid particle solar receivers

Parametric study on the performance of a solid particle solar receiver

“…Diverse chemical reaction cycles for hydrogen production are compared in scientific researches to obtain the environmentally friendly, large-scale, low cost and high efficiency process of hydrogen production (Abanades et al, 2006;Nielsen, 2005;Koroneos et al, 2004;Tan et al, 2009;Tan and Chen, 2010). The solar-driven thermo-chemical water-splitting (TCWS) cycles may be an ideal choice for hydrogen production, which requires a high temperature input to split water into hydrogen and oxygen.…”

“…The solar-driven thermo-chemical water-splitting (TCWS) cycles may be an ideal choice for hydrogen production, which requires a high temperature input to split water into hydrogen and oxygen. For example, the sulfur-iodine (S-I) cycle of hydrogen production process requires a reaction temperature of 850°C (Tan et al, 2009;Tan and Chen, 2010;Raissi, 2005, 2007). Solar central receiver systems are commonly used to concentrate the solar energy, which uses a heliostat field with large scale to reflect and focus the sunlight on a receiver located at the top of a solar tower.…”

“…Most solar receivers have an open aperture in the front to allow the concentrated sunlight to enter the cavity. However, a large amount of heat might be lost from the aperture by both convection and radiation (Tan et al, 2009;Tan and Chen, 2010). Taussig investigated the influences of a protective air-jet on solid particle solar receivers (SPRs) which reduces the convection heat loss by isolating the interiors of SPRs (Taussig, 1984).…”

“…The aerodynamic and thermal interaction between gas flow and solid particles in a three-dimensional design was investigated by Chen et al, based on the conceptual design provided by SNL (Chen et al, 2007). Tan et al conducted the investigation of wind effect on the performance of the SPRs and the protection of an aero-window formed by an air-jet (Tan et al, 2009;Tan and Chen, 2010). The development of the SPR technology has been reviewed by Tan and Chen (2010).…”

A numerical investigation of gas-particle suspensions as heat transfer media for high-temperature concentrated solar power

“…The use of particles as an intermediate HTM was experimentally studied in a fluidized bed [14] and in a freely falling, directly irradiated curtain [15]. Due to their stability at temperatures up to 1000°C, particles made of alumina, silica, silicon carbide (SiC), or zircon, are especially attractive [16]. Because typical specific heat capacities of these materials are comparable to those of molten nitrate salts, particles are suitable as thermal storage media [17].…”
