Abstract: A solar receiver includes at least two receiver panels having a common outer front surface for receiving incident solar radiation from a field of mirrors. The receiver panels include an array of side by side arranged heat exchange tubes which have a substantially straight main portion which extend in an upwards longitudinal direction and an inwards extending portion for a connection to an input or output header for respectively distributing or collecting fluid to or from the heat exchange tubes. The receiver panels are spaced apart in the upwards direction at a distance of Z cm. The header for the solar receiver is spaced behind the front surface at a distance of A cm, wherein the quotient of Z and A, Z/A, at the most equals the quotient of a vertical V and a horizontal H distance, V/H, from the header to a most far positioned mirror.

Abstract: A steam water separator includes:—a vessel having a vessel wall delimiting an interior of the vessel, where the vessel is configured to contain steam in a steam zone and water in a water zone in the interior of the vessel,—at least one inlet for introducing steam and/or water in the vessel,—at least one steam outlet for taking steam out of the vessel,—at least one water outlet for taking water out of the vessel, and a wetting device configured to wet in the steam zone an inner surface of the vessel wall.

Abstract: A steam generation system comprises a main steam generator and a back-up steam generator (20) which are both in fluid communication with a super heater (3) for superheating the generated steam. The superheater comprises a main heat source (6) for heating up a flow of heating gas. A back-up evaporator (2) is provided as a back-up steam generator for evaporating supplied water into steam. The back-up evaporator is connected in parallel to the main steam generator. An auxiliary heat source is provided for heating up the back-up evaporator. By controlling the auxiliary heat source (9), it is possible to supply more or less heat energy to the back-up evaporator to compensate for fluctuations in steam production of the main steam generator. The back-up evaporator is positioned away from the flow of heating gasses departing from the main heat source.

Abstract: An evaporator system for an industrial boiler is provided and includes a heat-transfer system for generating a water-steam mixture. At least one horizontal vessel is provided for the primary separation of water and steam. At least one vertical vessel is provided and contains a water level great enough to create the necessary pressure to force the separated water to flow back from the vertical vessel to the evaporator system. The horizontal vessel and the vertical vessel are connected to one another by a piping through which the separated wet steam is transported from the horizontal vessel to the vertical vessel. The horizontal vessel has a connection to a piping for receiving water. The vertical vessel has a connection to piping for extracting dried steam from the vertical vessel.
