Abstract:Solar Tower thermal (ST), Parabolic Trough thermal (PT), Linear Fresnel thermal (LF) and Solar PV are discussed in the context of suitability for hybridization with biomass in Europe.Technical, economical and climate data have been compared to identify the key drivers of technology selection in setting up large scale solar-biomass hybrid power plants. The sole solar-biomass hybrid power plant is currently in operation in Spain uses PT technology due to its performance characteristics, comparatively easy installation process compared to ST and relatively higher heat and optical gain than LF. The climate condition in the EU shows that the region within average yearly direct normal irradiance (DNI) 1400 -1800 kWh/m 2 can be useful for CSP hybridization as the distribution periods of high intensity of DNI of solar energy justify integrating biomass. Of the three concentrated solar power (CSP) technologies, ST provides the best overall efficiency for combined heat and power (CHP) generation.

“…Linear Fresnel collectors are one of two viable line-focus CSP technologies, along with the parabolic trough [19,53]. Linear Fresnel collectors utilize an array of low-profile, flat or nearly flat primary reflectors and a fixed receiver assembly that includes one or more linear receiver tubes and an optional secondary reflector.…”

“…Linear Fresnel reflector system provides low-cost alternative due to simple structure and receiver, compared to PTC system (Xie et al 2012). However, LFR field produces much lower energy per unit area of solar collector field compared to the PTC field, and there is a need to improve the annual optical efficiency of LFR field (Zhu et al 2014). The optical performance of the LFR field is affected by the latitude of the place, day and time, length and width of reflector, spacing between adjacent rows, the number of reflector rows in each loop, height of the receiver above the ground level, type of receiver, cleanliness factor, etc.…”

Concentrated solar power (CSP) plant is an emerging technology among different renewable energy sources. Parabolic trough collector (PTC)-based CSP plant, using synthetic or organic oil as a heat-transfer fluid, is the most advanced technology. About 87 % of the operational capacities of CSP plants worldwide are based on PTC technology. Direct steam-generating linear Fresnel reflector (LFR) systems have been developed as a cost-effective alternative to PTC systems. Line-focusing concentrating solar collectors (PTC and LFR), with single-axis tracking, are simple in design and easy to operate. Prior to the detailed design of a CSP plant, it is necessary to finalize type of the solar field, type of the power-generating cycle, overall plant configuration, sizing of the solar field and the power block, etc. The optimal design of a CSP plant minimizes the levelized cost of energy for a given site. In this paper, a detailed review of important design parameters which affect the design of line-focusing concentrating solar collector-based power plants is presented. This includes parameters for solar collector field design, receiver, heat-transfer fluid, thermal energy storage, powergenerating cycle, sizing and configuration of the plant, etc. This review may provide a reference for designing CSP plants. Future research directions are also identified.

“…Furthermore, the linearity of the linear Fresnel internal mirror was modified and the optical efficiency of the linear Fresnel field was also enhanced. There are different LFC receiver technologies: cavity receivers with an array of parallel tubes [8] [9], utilized by ArevaSolar and among others, are included by Novatec Solar and Solarmundo [10], as well as single tube receiver with other geometries secondary reflector [11], Qiu et al [12] [13] performed the study of the coupling heat transfer process of radiation-conduction-convection in LFR heat absorbers under non-uniform energy flux distribution boundary conditions, analyzed the photo-thermal conversion performance of the LFR system, in addition to obtaining the non-uniform temperature distribution of the surface of the absorber tube. then analyzed the changes of the optical efficiency of the system subjected to varied angles of incidence.…”

In this paper, on the base of principle of linear Fresnel reflective collector, a three-dimensional framework of linear Fresnel reflector field (LFR), compound parabolic collector (CPC) and the absorber tube with selective absorption coating and glass tube were established, together with calculating optical efficiency of the vacuum tube collector at different incident angles of the linear Fresnel system in the cold region. As revealed by the findings, the angle of light was in the range of 0˚ -60˚, and the optical efficiency amounted to be the lowest at the incident angle of 15˚. When the incident angle was 75˚, the optical efficiency displayed an obvious reduction, and as the incident angle was 0˚, the distribution of the energy flow in the tube was more standardized. Because of the incidence of the end loss, some tube length is unable to flow in the direction. For the purpose of performing the experiment the thermal performance of linear Fresnel system in the cold region, introduction of the thermal transfer factor was made, together with the analysis of the measured data under the condition of no loss of the receiver. The maximum theoretical efficiency of the system amounted to 68%, and the optical loss was approximately the total solar radiation at 32%.
