“…Figure 4 illustrates various elements of a typical thermal power plant, whose function is to convert heat into electricity. These components start with the source of the heat (thermal energy), which can be from burning a fossil fuel, from a nuclear reactor, or from concentrating the solar radiation [17]. The exact source is not specified in this work, and is left to the operator or owner to select.…”

An analysis for a conceptual design of a thermal power plant (with a power capacity of 1 GW) is provided. This power plant can help in meeting the expected increase in the electric demand for Oman's dominant power system (2.4 GW between 2018 and 2025). A necessary fluid mass flow rate of 834.1 kg/s was predicted. The overall energy conversion efficiency (output useful electricity divided by input heat) was estimated to be 34.7%. The needed thermal energy is not restricted to a specific source, and solar heating is an option for supplying the needed heat. The power plant design is based on using a steam-turbine section, which may be composed of a single large steam turbine having a mechanical power output of 1115 MW; or composed of a group of smaller steam turbines. The analysis is based on applying energy balance equations under certain assumptions (such as neglecting changes in potential energy). The thermal analysis was aided by web-based tool for calculating needed properties of the working medium, which is water, at different stages in the power plant.

Concentration of solar energy may be obtained by reflection, refraction, or a combination of the two. The collectors of a reflection system are designed to concentrate the sun’s rays onto a photovoltaic cell or steam tube. Refractive lenses concentrate light by having it travel through the lens. The sun’s rays are partially reflected and then refracted via a hybrid technique. Hybrid focus techniques have the potential to maximize power output. Fresnel lenses are an efficient tool for concentrating solar energy, which may then be used in a variety of applications. Development of both imaging and non-imaging devices is occurring at this time. Larger acceptance angles, better concentration ratios with less volume and shorter focal length, greater optical efficiency, etc., are only some of the advantages of non-imaging systems over imaging ones. This study encompasses numerical, experimental, and numerical and experimental studies on the use of Fresnel lenses in various solar energy systems to present a comprehensive picture of current scientific achievements in this field. The framework, design criteria, progress, and difficulties are all dissected in detail. Accordingly, some recommendations for further studies are suggested.

Introducción. La energía solar térmica (EST) encargada del aprovechamiento de la radiación solar para transformarla en calor es una de las formas más alentadora de generación. Objetivo. Efectuar una investigación mediante la revisión sistemática de la literatura (RSL) para responder la interrogante que nos dice ¿Cuáles son los métodos más precisos para la elaboración de un sistema de calentamiento eficiente utilizando energía solar? Metodología. Se trabajó en base a las tres fases de la RSL, que son la planificación, la conducción y la revisión. La base de datos estuvo delimitada a un periodo de 6 años, a partir del 01 de enero de 2016 al 8 de agosto de 2022. Resultados. Los resultados determinaron que las mejores formas de calentamiento es el uso de EST concentrada. Los Colectores Solares Fresnel (CSF) tipo lente generan una eficiencia variable de aproximadamente un 70%. Conclusiones. Se concluyó que los métodos más eficientes para calentamiento de agua o generación de vapor son los colectores solares tipo lente con temperaturas superiores a los 100°C y los colectores de tubos al vacío con temperaturas aproximadas de 120°C, sin embargo, se conoce que las lentes Fresnel varían dependiendo de la cantidad de radiación en el ambiente, por esto, puede llegar a tener temperaturas de hasta 600°C dependiendo de las condiciones climáticas del lugar.
