...Sanan T. Mohammad; Hussain H. Al-Kayiem; Ayad K. Khlief; Mohammed A. Aurybi This study presents a conceptual design for a concentrated solar power plant by using direct steam generation and a stand-alone power system based on a concentration of solar parabolic troughs. The system is located...

...Marwan Mokhtar; Christian Zahler; Robert Stieglitz Solar direct steam generation (DSG) systems are well suited for process steam applications and are able to provide steam at the pressure required by common industrial processes. Nevertheless, reliable control has always been a challenge for solar...

...Marwan Mokhtar; Christian Zahler; Robert Stieglitz Direct steam generation (DSG) is a technology used to produce steam from a solar concentrated thermal plant directly in the solar field without the use of an intermediate steam generator. This technology is attractive due to economic considerations...

...Doerte Laing; Thomas Bauer; Dorothea Lehmann; Carsten Bahl For future parabolic trough plants direct steam generation in the absorber pipes is a promising option for reducing the costs of solar thermal power generation. These new solar thermal power plants require innovative storage concepts, where...

... for the DISS direct steam generation facility at the Plataforma Solar de Almeria (Spain). In order to deal with the problems of large dimensionality and high correlation among the data the methods of latent variables, principal component analysis and partial least squares, were applied. Results showed...

...Tobias Hirsch; Markus Eck The dynamic behavior of a parabolic trough collector field with direct steam generation under varying solar conditions is analyzed using a transient simulation model. It is found that the peak water flow rates observed during transients may reach several times the steady...

...Markus Eck; Holger Schmidt; Martin Eickhoff; Tobias Hirsch Direct steam generation (DSG) represents a promising option to improve today’s parabolic trough technology for solar thermal power generation. The European DISS and INDITEP projects have proven the feasibility of the DSG process under real...
