Power generation using renewable technologies has become a primordial option to satisfy the energy demand all over the world, being solar concentrating technologies widely applied for this purpose. A combination of Parabolic Trough Collector with Direct Steam Generation has been considered an excellent option for power generation, due to the economic cost and complexity in the plant are reduced. The thermal evaluation of the solar power plant as well as the PTC in the DSG process is very important in viability and economic analysis. In this sense, as the main objective of this work, a numerical tool for evaluating DSG with PTC technology has been developed. The software SOLEEC is a versatile, reliable, accurate and friendly to the user for thermally evaluating a DSG with PTC technology. The user has the possibility to compare the thermal behavior of different geometrical dimensions for a PTC; and even consider different materials; in order to satisfy the demand of superheated steam by a DSG process. The software has an error less than 5% when compared with literature results and in this paper is used to evaluate a power plant in Mexico obtaining that the change to DSG proposing different PTC could reduce the solar field about 35%.

“…La correlación de Chan (Enciso, 2012) considera un flujo bifásico, tiene dos componentes principales la formación de burbujas y el fenómeno de convección. Para obtener el coeficiente de transferencia de calor, que corresponde al patrón de flujo burbujeante, se determina usando la correlación de Baehr-Stephan (2006).…”

The use of solar plants as auxiliary systems in conventional power combined cycles has contributed to the evaporation process, reducing the use of fossil fuels for steam generation. The present work is focused on the analysis and design of sizing the optimum solar field for being implemented in the fourth unit of the combined cycle power plant “Valle de México” in Mexico. The software SOLEEC is used to determine the collector geometrical features based on the absorber tube external diameter; in this study, three cases have been analyzed, 2, 3, and 4 in. absorber tube diameters. The best collector's geometry depends on the steam temperature, the working pressure, and the mass flow necessary to supply the overheated steam; also, the total aperture area of the field, the total reflective surface area, and the thermal efficiency for every case have been obtained; the absorber tube is divided into three sections: preheating, evaporation, and overheating and the collector is considered in Once Trough mode. Once the geometrical and thermal characteristics are obtained for the three designing configurations, an analysis is carried out to determine the advantages of the best configuration that would be selected for this specific application. According to the results, the best geometry is the one with 2 in. in the absorber diameter, producing a fraction of 50.3 kg/s of steam.
