Description
Technical field
The present invention relates to a kind of solar energy heat collector, the asymmetric groove type solar collection of a kind of combination glass sunlight house
Thermal, belongs to technical field of solar utilization technique.
Background technology
The commercial development of solar energy and utilization are an important development trend of field of renewable energy, International Energy Agency
(IEA) it is expected that more than the 20% of world power supply will be accounted for the year two thousand forty solar electrical energy generation.Concentration type solar generation technology
A kind of important way as Solar use, it has also become one of important directions of international heliotechnics development.China " can be again
Raw energy development Eleventh Five-Year Plan " in the most clearly propose, on Ordos, inner Mongolia highland along the Yellow River smooth desert, Gansu
The smooth desert in Hexi Corridor, Hami area, Lhasa or Beijing periphery select suitable area, carry out solar energy thermal-power-generating
Pilot work.
By the difference of heat collector type, concentration type solar electricity generation system can be divided into trough system, tower system and dish
Formula system three major types.Put into practice by the research and development of more than 30 years, reach common understanding in the world: solar energy thermal-power-generating station, wherein
Groove type solar thermo-power station is the most most economical solar electrical energy generation mode, and only trough type solar power generation achieves business
Industryization is run, and is the most ripe solar energy thermal-power-generating technology.Solar parabolic through power generation system is by paraboloid trough type optically focused
