2. InSun
Industrial Process Heat by Solar Collectors
Research Project funded from the European Union's Seventh Framework Programme FP7
Target: Investigation of 4 different cases in general
• process water preheating (flat plate and vacuum tube collectors)
• Steam generation through concentrating collectors (direct and indirect)
This case: Feed water preheating
throughout flat plate collectors

• Wide variation of different
locations and system sizes
12 locations
collector size 200 – 2.200 m²
storage size 2 – 200 m³
Daily load 200 kWh – 100 MWh
2.800 different results!
Results will be available for free to the public via easy to use Web-Tool
