Prototype of lineal solar collector Fresnel

Abstract

The development of a prototype linear solar collector Type Fresnel, has a purpose the use of direct solar heat radiation for water heating and/or steam production, as an alternative to supply conventional water heating systems or steam generators, which consume energy from fossil fuels.
 For the development of the system, used the solar radiation of the UTS, located in Bucaramanga, Colombia, is identify the mathematical models to perform the sizing, then materials based on technical specifications and availability in Colombia, in order to perform the assembly and field tests, measuring the ambient and in the collector temperature to determine the efficiency of the model.
 It should be noted that, the model presented does not have a control system for flow, temperature, pressure and level, it has no solar tracking of any kind; Its movement was done manually with each reflex. Finally, the model does not have a hydraulic system forced, and has a preheater at the entry of the concentration point.

Modeling of a solar thermal system as a power supply alternative for a resistor water distillation system using TRNSYS

“…Thus, as non-conventional renewable energies [7] [8] will play an important role for humanity [9], being an alternative solution to supply in the future, percentages of energy demand worldwide. Eventually, various developments in the use of solar radiation through small-scale [10] or large-scale thermo-solar plants; integrated with photovoltaic [11] [12] or solar concentration [13] [14], systems, 1299 (2024) 012011 IOP Publishing doi:10.1088/1757-899X/1299/1/012011 2 they have been implemented worldwide as a source of electrical and thermal energy production [15] [16].…”

Performance evaluation of a parabolic cylinder collector applying the Monte Carlo ray tracing method

“…For the production of thermal energy, solar thermal systems stand out from photovoltaic systems due to their capacity to reach operating temperatures above 1000°C [4]. Solar thermal systems can be technologically classified into three systems [5]; (i) low-temperature (1D) systems that reach up to 100 °C, (ii) medium-temperature (2D) systems that reach temperatures up to 300 °C [6], and (iii) high temperature (3D) systems with temperatures around 1000 °C. In the last decade, 2D and 3D systems have been referred to as Concentrating Solar Power (CSP) systems and have gained significant relevance due to their high participation in centralized systems around the world [7].…”

“…2D CSPs operate on the principle of linear solar concentration and are divided into two technologies [8]; (i) parabolic trough collectors (PTC) and (ii) linear Fresnel collectors (LFC) [9], [10]. On the other hand, 3D CSPs operate on the point concentration principle and are divided into two technologies [11]; (i) dish-striling and (ii) concentrating tower.…”
