Solar thermal power generation equipment

Abstract

The invention relates to a solar-thermal power plant (1) having direct vaporization of a thermal carrier having parabolic channel collectors (4a, 4b), each consisting of a plurality of parabolic channel segments (5), wherein thermal energy of the sunlight can be supplied to the thermal carrier via the parabolic channel collectors (4a, 4b), and having at least one vapor turbine (20) which can be driven by the vaporized thermal carrier, wherein the parabolic channel collectors (4a, 4b) are arranged in a plurality of loops (6a, 6b), wherein the loops (6a, 6b) are connected parallel so that a first number of parabolic channel collectors (4a) form a vaporizer (2) and a second number of parabolic channel collectors (4b) form a superheater (3).

Description

technical field [0001] The invention relates to a solar thermal power generation device which uses a heat carrier to directly evaporate. Background technique [0002] Solar thermal power plants exist in a variety of ways. In addition to solar tower power plants and Fresnel collector plants, there are also parabolic trough power plants, which reflect sunlight via parabolic trough-shaped reflectors to tubular absorbers through which the heat-carrying medium passes . Several such parabolic trough shaped reflectors, also called parabolic trough segments, combine to form a parabolic trough collector. [0003] Parabolic trough power plants are commonly used to generate steam to operate steam turbines using conventional water steam circuits. Usually, in this respect, two different structural designs are used. In a common type of system, the oil is heated through a parabolic trough collector, where the oil transfers thermal energy to the water vapor circuit via a heat exchanger....
