Feed water preheating through flat plate collectors: parametric studies - Marcus Brunnenstuhl

  1. 1. InSun Industrial Process Heat by Solar Collectors Research Project funded from the European Union's Seventh Framework Programme FP7 ENER/FP7/296009/InSun Industrial workshop on solar process heat, Sardegna 2015 Marcus Brennenstuhl M.Sc. Zafh.net
  2. 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 ENER/FP7/296009/InSun Industrial workshop on solar process heat, Sardegna 2015 Marcus Brennenstuhl M.Sc. Zafh.net • 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 2
