Compound parabolic solar concentration type molten salt steam generator

Abstract

The invention relates to a compound parabolic solar concentration type molten salt steam generator which comprises a solar reflecting device and a steam generator body, wherein in the steam generator body, a lower boiler barrel is arranged under an upper boiler barrel, and molten salt tanks are symmetrically arranged on the two sides; a compound parabolic reflector which can concentrate sunlight reflected by the solar reflecting device to the corresponding molten salt tank is arranged on the upper surface of the molten salt tank on each side; a steam outlet and a water filling pipeline connector are connected to the upper surface of the upper boiler barrel, and an ascension pipe and a hot pipe are connected to each side; each ascension pipe penetrates the molten salt tank on the same side to be communicated with the lower boiler barrel from top to bottom, and each hot pipe extends into the molten salt tank on the same side; the bottom of the upper boiler barrel is connected with a down pipe which is communicated with the lower boiler barrel; a molten salt outlet and a molten salt inlet in the two ends of each molten salt tank are communicated with each other through a molten salt pipeline, and a molten salt pump is mounted on the molten salt pipeline. The steam generator can be placed on the ground and is compact in structure, low in cost and quick in start.
