Project description The main idea of InSun was to demonstrate the reliability and quality of large scale solar thermal systems for different types of industrial process heat applications on medium and high temperature levels. A broad application of this quite young technology has the potential to significantly reduce the CO2 emissions and the dependency on oil and gas imports in the industrial sector. InSun also demonstrates the variety of solar system options (non-concentrating – flat plate collectors and tracked concentrating collectors) for solar process heat applications in different industrial processes including different climatic regions from moderate to hot and dry European and extra European countries. To support the marketing for solar process heat applications detailed simulation studies which analysed the different collector technologies applied to various industrial processes in several countries and climatic conditions have been carried out to highlight the most appropriate applications (energetic + economically) for the different collector technologies. Three types of collector systems are demonstrated and compared: tracked concentrating Fresnel collectors for an Italian brick drying factory at 200°C, improved flat plate collectors for an Austrian meat factory for hot water preparation and steam pre-heating up to 95°C and parabolic trough collectors (originally planned for a milk powder production in Spain). However, due to several reasons the Spanish partner left the project, and therefore this system could not be installed although the planning and fabrication of the collectors were completed. As an alternative a small scale parabolic trough collector field is installed to operate as temperature booster of the already installed flat plate collector field at the Austrian meet factory to increase the heat amount transferred to the steam boiler. Each of these applications offers a high replication potential.
