Abstract

The invention relates to a stationary reflecting surface concentrating solar boiler which comprises a stationary reflecting curved surface (10) and a movable solar heat collector (30), wherein the stationary reflecting curved surface (10) can form a light spot (20) which can move along with the radiation angle of sunrays; the movable solar heat collector (30) is arranged in the light spot (20) and can move along with the light spot (20). The reflecting curved surface (10) is the curved surface formed by leading part of elliptic line of an oval to rotate around a short shaft. The movable solar heat collector (30) consists of at least one solar vacuum heat collecting pipe (31) and a light spot tracking motion mechanism (32). The stationary reflecting surface concentrating solar boiler does not need to track the sunrays through the motion of the reflecting surface and can realize the concentration of the sunrays by tracking the light spot formed by being reflected via the stationary special reflecting surface and concentrating the sunrays, thereby having high light-heat conversion efficiency, easy installation, use and maintenance, low manufacturing cost and a wide range of uses.

Description

【Technical field】 [0001] The invention relates to a solar energy device, in particular to a static reflecting surface concentrating solar energy boiler. 【Background technique】 [0002] As everyone knows, solar energy is inexhaustible, but people have not yet been able to use it on a large scale. With the reduction of fossil energy such as coal, oil, and natural gas and the continuous rise in price, it has become more and more important for humans to directly obtain energy from solar energy. At present, various solar energy utilization devices have been used, such as photoelectric conversion and photothermal conversion devices. Larger solar concentrators include trough and tower systems. Whether it is a trough system or a tower system, it is necessary to track the sun's rays by rotating the reflective surface, which makes it expensive, inconvenient to install and maintain, and high in operating costs, so it is not suitable for installation on the roof of a building. 【Cont...
