Conceptual design of a solar receiver to generate water vapor in dish parabolic concentrators

Abstract

Massive energy generation requires the management of large amounts of water vapor, because heat has to be introduced that allows the temperature to be raised above 1000 °C to generate superheated steam capable of moving generators to produce electricity; for example, The technology of Disk Parabolic Concentrators. In this sense, is not yet mature enough, but it is promising, because studies have shown that the parabolic disk collector system is more efficient, stable, predictable and reliable than other systems, because it concentrates solar energy in a receiver that it assimilates and then offers the possibility of storing it for then continue to use it in about 7 hours, which cannot be said about other systems not foreseen for energy storage or with highly polluting energy deposits such as photovoltaic energy. In this work, the solar receiver is proposed together with its storage system, because all the concentrated energy is managed there and where the efficiency of the entire system is determined, it is a critical process. The objective of this work has been to develop conceptually an optimal proposal taking into account materials, conditions and configurations that have been studied and in which it has finally been concluded that they are advantageous. All this, has been done through the VDI 2221 design methodology that has helped to order the process and get the appropriate data. The design of a more optimal conceptual system has been obtained according to the most recent information, achieving the best efficiency, the most optimal configuration and not losing sight of the duration of the system, avoiding thermal and hand stress to avoid materials with a high carbon footprint, as much as possible.
