Abstract: A heat exchanger includes an inlet for receiving bulk solids, a plurality of heat transfer plate assemblies, a plurality of spacers disposed between adjacent heat transfer plate assemblies, and supports for supporting the heat transfer plate assemblies. The heat transfer plate assemblies include a first plate having a first pair of holes extending therethrough, the first plate having channels extending along a surface thereof, for the flow of fluid through the channels, and a second plate bonded to the first plate to enclose the channels, the second plate including a second pair of holes generally aligned with the first pair of holes to form through holes to facilitate flow of the fluid through the through holes and the channels.

Abstract: Described herein are technologies pertaining to computing the solar irradiance distribution on a surface of a receiver in a concentrating solar power system or glint/glare emitted from a reflective entity. At least one camera captures images of the Sun and the entity of interest, wherein the images have pluralities of pixels having respective pluralities of intensity values. Based upon the intensity values of the pixels in the respective images, the solar irradiance distribution on the surface of the entity or glint/glare corresponding to the entity is computed.

Abstract: Various technologies pertaining to aligning and focusing mirrored facets of a heliostat are described herein. Updating alignment and/or focus of mirrored facets is undertaken through generation of a theoretical image, wherein the theoretical image is indicative of a reflection of the target via the mirrored facets when the mirrored facets are properly aligned. This theoretical image includes reference points that are overlaid on an image of the target as reflected by the mirrored facets of the heliostat. A technician adjusts alignment/focus of a mirrored facet by causing reflected reference markings to become aligned with the reference points in the theoretical image.
