Solar steam generation with vacuum can be applied for numerous evaporation processes e.g. in food and beverage industry, since typical process temperatures are in the range of 40 - 80 °C. Therefore, an evacuated storage with a conventional heat exchanger is required. The condensate from evaporation process is preheated by solar energy and fed into the evacuated storage. The evaporated condensate is fed back into the evaporation process. | Solar steam generation with vacuum can be applied for numerous evaporation processes e.g. in food and beverage industry, since typical process temperatures are in the range of 40 - 80 °C.

+ | For solar steam supply with reduced pressure of 1.5 - 3 bar (according to 110 - 135 °C) a kettle reboiler is required that is supplied with solar heat. Feed water or condensate is fed into the reboiler, evaporated and used to heat the process. Therefore, the conventional steam demand for injection heating is reduced. Based on the required installations this integration concept is similar to SL_S_PI on supply level. The only difference is the reduced temperature level compared to conventional steam systems in Industry. Therefore, this integration concept can also be applied under moderate climatic conditions. |
