Abstract:
A solar light collecting mirror includes a reflective section which is elastically deformable, and a frame which is elastically deformable and configured to support the reflective section. A central portion of the reflective section is positionally fixed in X and Y directions of the reflective section. A relative position in a Z direction between the central portion of the reflective section and a peripheral portion of the reflective section is changeable. The peripheral portion of the reflective section is not positionally fixed in the X and Y directions. The frame includes warp members which radially extend from a position corresponding to the central portion of the reflective section. And the reflective section is configured to deform elastically together with the frame so as to change the relative position in the Z direction between the central portion and the peripheral portion, whereby a concave mirror structure is obtained.
Abstract:
A solar light collecting mirror is configured such that a protruding section of a substrate, using as a reference position the position of an inscribed circle in a reflective section, impels the rear surface of the reflective section further on the outside in the radial direction than the reference position. As a result, the surface of the reflective section further on the outside in the radial direction than the reference position bends towards the surface side in the Z direction.
Abstract:
Provided are a solar light collecting mirror which can achieve high light collection efficiency even in a solar thermal power generation system such as a tower solar thermal power generation system in which the distance from a reflecting mirror to a heat collector is a long distance between several tens of meters and several hundreds of meters, can be manufactured easily and inexpensively, and can easily achieve concave mirrors with various curvatures, and a solar thermal power generation system using the same. A solar light collecting mirror (SL) of a heliostat (15) close to a light collecting mirror (11) serves as a concave mirror with a relatively small curvature by setting the relative rotation amount between a nut (NT) and a bolt (BT) large, and a solar light collecting mirror (SL) of a heliostat (15) distant from the light collecting mirror (11) serves as a concave mirror with a relatively large curvature by setting the relative rotation amount between the nut (NT) and the bolt (BT) small, thereby achieving a solar thermal power generation system having high light collection efficiency in total.
Abstract:
An absorber that uses a gasified gas containing CO2 and H2S formed by gasifying coal, for example, as an introduced gas, and that makes the CO2 and H2S absorbed from the introduced gas by bringing the introduced gas into contact with an absorbent for absorbing C02 and H2S; an absorbent regenerator-that extracts absorbent that has absorbed CO2 and H2S from the bottom of the absorber and introduces the absorbent from the top of the absorber, and that regenerates the absorbent by releasing the CO2 and H2S; a second supply line that returns the regenerated absorbent from the regenerator to the absorber; and a third supply line that extracts the absorbent (semi-rich solution) that has absorbed a part of the CO2 and H2S from the vicinity of the middle of the absorber, and that introduces the semi-rich solution in the vicinity of the middle of the regenerator.

Abstract:
An optical element for reflecting solar light has excellent weather resistance, and furthermore, a high reflectance in a wide band. When solar light enters an optical element (OE), light (L1) in a short wavelength band among the solar light is reflected by a dielectric multilayer film (DF). Other light (L2) in longer wavelength bands are passed through the dielectric multilayer film (DF), then a base material (SS), and reflected by a metal deposition film (MV) to pass through the base material (SS) and the dielectric multilayer film (DF). Thus, high reflectance in a wide band is ensured.
