Problems solved by technology

However, introducing additional optics would in practice involve additional energy losses due to thermal / optical effects such as absorption, repulsion, re-radiation, convection and spillover at the surface of the secondary concentrator
The presence of secondary concentrators adds to the complexity of the design of solar tower installations

Embodiment Construction

[0051] As described in the previous section, the central tower solar concentrating technology mainly consists of a solar field consisting of a structure with a plurality of individual mirror elements or heliostats (11), which are usually constructed For a large spherical cap or paraboloid, the fixed receiving element is located at the focal point of the spherical cap or paraboloid. figure 1 A schematic diagram of a tower solar concentrator system is described in . The solar radiation from the sun (10) strikes the reflective surface of the heliostat (11) through the specific configuration of the tower solar concentrating system (the reflective surface of the heliostat (11) usually consists of one or more facets) , tracking the movement of the sun (10) and concentrating and focusing the sun's rays on a tower (12), the tower (12) including a solar receiver (13) at the top of the tower (12). The receiver (13) thus absorbs the radiation from the heliostat (11) and transfers the ra...

Abstract

The invention relates to an asymmetric solar receiver (13) suitable for its installation in heliostat (11) tower solar power plants, wherein said receiver (13) is adapted to cover at least an angular region of 180 degrees around a tower (12), and wherein the effective surface density of the receiver (13) for receiving radiation varies depending on its orientation over the covered angular region thereof. The effective surface of said receiver (13) is preferably made of one or more panels and, more preferably, the receiver (13) comprises at least two panels, wherein at least one of the panels comprises a smaller height than the other panels. The invention also relates to a solar tower (12) comprising said receiver (13), a solar field comprising said tower (12), a solar power plant comprising said solar field, and a process for installing a solar field.

Description

technical field [0001] The present invention relates to the technical field of thermal concentrating solar power (Concentrating Solar Power, CSP) technology, concentrating solar power plant (solar power plant) technology, and particularly relates to solar power tower concentrating technology. Background technique [0002] Concentrated solar power (CSP) technology is an important alternative for clean and renewable power generation. CSPs use the heat of the sun - an unrestricted and daily available energy source, which allows reducing greenhouse gas emissions by approximately 1kg for every kilowatt of electricity produced. Ease of management, dispatch capability and capacity to adapt to electricity market demands make CSP the most interesting of renewable technologies and competitive with fossil fuel power plants. Currently, there are four main CSP technologies, namely Parabolic Trough Technology (PTC), Linear Fresnel Collector (LFC), Stirling / Dish Systems (SDC) And solar t...
