Problems solved by technology

It is known from the public information that the trough solar thermal power generation technology used is the traditional technology 30 years ago. This technology has not made a major breakthrough so far. Its structure is complex, there are many hardware equipment, and the initial investment remains high. With technological improvement, it is difficult to realize government plans and business expectations in the face of China's less abundant CSP resources

Abstract

According to a multi-mode groove-type solar thermal power generator provided by the invention, through selection of fuel gas complementary thermal storage and two-tank or single-tank thermal storage new technologies, organic combination with different types of power units such as a Rankine steam power unit, a supercritical Bretton power unit and an air Bretton power unit, and complementation of solar energy and other renewable energy, heat transfer and storage media, a solid filling heat storage technology and an appropriate thermal power technology which adapt to the domestic natural geographical environment are selected as far as possible; and a brand new technical route is provided for simplifying the structure, reducing the cost, increasing the power generating hours, enlarging the userange and reducing the hardware investment. The multi-mode groove-type solar thermal power generator belongs to the technical field of solar thermal power generation.

Description

Technical field [0001] The multi-mode trough solar thermal power generation device of the present invention selects the new technology of gas complementary heat storage, two-tank or single-tank heat storage, and organically combines with different types of power units such as Rankine steam, supercritical Brayton, air Brayton, etc., while taking into account Solar energy and other renewable energies complement each other. As far as possible, select heat transfer and heat storage media, solid-filled heat storage technology, and appropriate thermal power generation technology that are compatible with the domestic natural geographic environment. This will simplify the structure, reduce costs, extend power generation hours, and expand The scope of application and the reduction of hardware investment put forward a brand-new technical route. The device belongs to the technical field of solar thermal power generation. Background technique [0002] On September 1, 2016, the Chinese gover...
