Direct Steam Generation (DSG) - Technology Overview [PDF]
Journal of Solar Energy Engineering, 2012 For the future market potential of parabolic trough power plants with direct steam generation (DSG), it is beneficial to integrate a thermal storage system. Heat storage media based on phase change materials offer heat transfer at constant temperatures needed for the evaporation process. Different options for a plant layout are presented and discussed.

Direct Steam Generation in Parabolic Trough Collectors
Energy Procedia, 2014 Existing commercial parabolic trough power plants use thermal oil as a heat transfer fluid, with working temperatures in the region of 400ºC. In order to achieve more efficient generating systems, a second generation of parabolic troughs that operate at temperatures higher than 400ºC is being developed.

Model Predictive Control For Direct Steam Generation in Paraboloidal Dishes
IFAC-PapersOnLine, 2018 Abstract The control of solar thermal systems is challenging due to the non-linear dynamic behaviour of the heat transfer process occurring at the receivers, such as direct steam generation. Model predictive controllers can outperform classical control approaches by incorporating nonlinear model behaviour and constraints.

Buffer storage for direct steam generation [PDF]
Solar Energy, 2006 Fast reaction times and high discharge rates make steam accumulators a promising option for compensation of fast transients in insolation for solarthermal systems using steam as working medium. Using the volume of components like separator drums or heat exchangers for storage of pressurized hot water is a cost-effective approach to integrate buffer ...
