SolarPower Technology

The solar power technology utilizes the reflectivemirror to reflect and concentrate the solar radiation to the parabolic troughtube and heat the heat transfer fluid (HTF) of the tube. Then, the heatexchange system will produce high-temperature and high-pressure superheatedsteam, which drives a steam turbine to generate power.

1.Concentrating Collector System
The system is composed of a large number of solar collector array (SCA) inseries and parallel. For the concentrating collector, it includes the collectortube, reflector plate, support frame, drive system and tracker system. Severalcollector arrays in series combine the collector loop, and many collector loopsare then connected in parallel to the high and low temperature main pipe, thusconstituting a large-scale solar concentrating collector field. The lowtemperature working fluid, such as conduction oil and molten salt, is heated toa high temperature one through this system, so as to convert solar radiationinto heat.

2. Heat Exchange System
This systemconsists of the heat exchanger, including the preheater, steam generator and superheater. The high-temperature working medium inconcentrating collector system orderly passes through the preheater, steam generator and superheater, thus becoming into the low-temperatureworking fluid, and generating superheated steam for the generation of the steamgenerating system.

3. Thermal Storage System
The system ismainly made up of the cold tank, hot tank, heat storage working fluid, thermalinsulation material and the heat exchanger. The working fluid in the cold tankflows to the hot tank using a pump. It is heated into the high-temperatureworking fluid through the heat exchanger and then stored in the hot tank. Aspart of the solar power can be stored, the stability of electricity generationis fully ensured. In addition, this also allows the power generation system toachieve 24 hours of continuous operation, so as to greatly improve the workingefficiency.

4. Steam Generation System
This system iscomposed of the steam turbine, generator and other related equipment to achievethe transformation from thermal energy to mechanical energy and electricalenergy.
