Guan Xuan! The first voyage energy-saving Dunhuang 100MW tower molten salt solar thermal power station successfully connected to the grid!




In the early morning of December 28, 2018, the first voyage of energy-saving Dunhuang 100MW molten salt tower solar thermal power station was successfully connected to the grid. This is the first voyage of energy-saving independent design, investment and construction. After the first phase of the photothermal power station, the technical practice after two years is another new landmark in Dunhuang, Gansu, and the first batch of 100-megawatt photothermal demonstration power stations in China. It is also a 100MW molten salt tower photothermal power station with the largest condensing scale, the highest heat absorption tower, the shortest construction period, and 24-hour continuous power generation, peugeot has become one of the few countries in the world that has mastered the technology of 100MW molten salt tower solar thermal power station.

The first voyage of energy-saving Dunhuang 100 MW molten salt tower solar thermal power station was selected as the first batch of "national solar thermal power generation demonstration projects" in 2016, and was vividly praised as "super mirror power station". The mirror field consists of more than 12000 heliostats around a 260-meter-high heat absorption tower. Each heliostat has a lighting area of 115.5 square meters and 35 sub-mirrors of 3.3 square meters, with a total lighting area of 1.4 million square meters. In the field covering an area of 7.8 square kilometers, 12000 multi-faceted heliostats surround the 260-meter-high heat absorption tower in concentric circles, like silver "sunflowers" blooming on the Gobi ". The project is equipped with an 11-hour molten salt heat storage system, which can achieve 24-hour continuous power generation, and the annual power generation can reach 0.39 billion kilowatt-hours.

In the course of the construction of the project, Shouhang was able to overcome all difficulties in energy conservation and finally handed over a satisfactory answer to the photothermal power generation industry today. Through years of self-owned technology accumulation and practical exploration on the first voyage energy-saving Dunhuang 10MW tower solar thermal power station, various technical problems have been solved, and the overall technology of the power station has been greatly improved on the basis of the 10MW power station.

The completion of this project is not only the first commercial demonstration of energy-saving photothermal power generation, but also a successful demonstration of photothermal power generation at the national level. Its successful grid connection represents the success of China's independent large-scale photothermal power generation technology, and will also Strengthen my country's influence in the international photothermal power generation market.
