Description

technical field [0001] The invention relates to a solar energy concentrating transmission device and a solar boiler photothermal power generation system thereof. Background technique [0002] The sun is 1.5*10 from the ground 8 km, irradiated to the upper boundary of the earth's atmosphere, the solar energy is about 1367w / m 2 , when passing through the atmosphere and absorbing part of the energy by air molecules, the attenuation is 1000w / m 2 . Solar power generation is a renewable clean energy that converts solar energy into electrical energy. Solar power generation is more and more popular among people and plays a wide role in people's life and work. [0003] There are two types of solar power generation: one is solar photovoltaic power generation, and the other is solar thermal power generation. At present, solar thermal power generation mainly reflects light to the solar thermal power generation receiving device by a flat or curved mirror field, and converts it into e...

Problems solved by technology

At present, solar thermal power generation mainly reflects light to the solar thermal power generation receiving device by a flat or curved mirror field, and converts it into electrical energy; because the traditional mirror field has a certain angle with the sun's rays, the effective lighting area is small; and mirror reflection The light is scattered, the light intensity is low, the transmission process loss is more, and the transmission distance is short
