Abstract
Recent worldwide concerns on CO2 emission and anticipation of fossil fuel decreasing usage have increased the number of research on renewable energy. In Brazil, several agendas were implemented in last years on attempts of diversifying the well-established hydraulic power plants for electricity production and minimizing environmental harmful effects. In this context, the solar energy is highlighted as a promising source since concentrated solar power (CSP) plants already represent a fair amount of total energy produced in developed countries such as USA. and Spain. Therefore, the aim of this work is to analyze the cavity of a CSP system and develop a basic thermal model. Therefore, heat losses in the cavity occurring by re-radiation and convection at the window have been studied, as well as heat losses in the cavity-receiver body. The model was successfully implemented and can be used for various applications.
