Non-edible oils are progressively being utilized for production of bio-diesel around the world which embraces the future assurance towards renewable energy. After the extraction of oil, 50–60% of the material, termed as de-oiled seed cake, goes waste due to the presence of toxins. The present...

The optical design of a concentration system for a solar furnace is studied, proposing several possible solutions. The foreseen use of this solar furnace is to test components and methodologies for solar applications. The analysis assesses and compares the optical performances of several...

A novel cost-effective solar furnace system is proposed to be consisted of a Non-Imaging Focusing Heliostat (NIFH) and a much smaller parabolic concentrator. In order to simplify the design and hence leading to the cost reduction, a fixed geometry of the NIFH heliostat is adopted in the novel...

In the year 1994 the DLR in Cologne inaugurated a 20 kW solar furnace for technological and scientific experiments. One of the main applications of the solar furnace is the research on photochemical reactions using concentrated sunlight. For this purpose exact knowledge of the spectral...

We evaluated optical performance of a solar furnace in the KIER (Korea Institute of Energy Research) by measuring the highly concentrated solar flux with the flux mapping method. We presented and analyzed optical performance in terms of concentrated solar flux distribution and power...

This paper presents a prediction procedure of the solar irradiance distribution on a plane parallel to the focal one of the Plataforma Solar de Almería’s Solar Furnace, within defined limits, as well as its application to test a sample of a volumetric solar receiver exposed to concentrated...

Solar volumetric-receivers have been successfully used in both electricity production and thermochemical applications. This paper studies the applicability of this technology to the production of process heat for high-temperature uses (573–1073 K).

Global change research communities are paying increasing attention to answering critical questions related to land-use change, questions which are at the root of many pressing socio-economic and environmental issues. In this regard, a huge number of models have been developed to support future...
