Abstract
Description
technical field
[0001] The invention relates to a solar energy utilization system, in particular to a cascade utilization system of dish-type solar photothermal energy. Background technique
[0002] Concentrating solar thermal utilization technology is one of the effective means of solar energy utilization. Generally, there are four types of solar concentrating technologies: trough type, tower type, dish type, and Fresnel type. Among them, dish solar technology has a higher concentration factor and can reach a higher temperature level. Moreover, dish solar technology has the advantage of flexible layout and can adapt to a variety of complex terrain conditions. It can not only operate independently as a small power source in remote areas, but also combine a larger number of dish devices to form a large-scale solar power station.
[0003] The traditional dish solar system uses a Stirling machine as the power generation equipment, and its cost remains high for a long time, an...
