Low-Steam-Generation-System

A Medors reflector is a parabolic dish that uses single axis tracking to follow the sun's daily course. These reflectors have a flexible reflective surface that is able to change its curvature to adjust to seasonal variations in the incident angle of sunlight. Medors reflectors have the advantage of having a fixed focal point which improves the ease of cooking and are able to reach temperatures of 300-600°C. This system uses parabolic concentrators of large surface areas that focus solar energy to receivers that convert water in the pipes to steam. The design procedure is simple, flexible and does not need any special setup, thus offering the end user the prospect of application in domestic as well as industrial configurations.  

Medors Solar maintains that parabolic trough technology can generate electricity at much more competitive prices due to the new fluids that can work at higher temperatures and the reduced costs of certain key components.

High temperatures

 

As one of the principal goals of R&D is to reduce the cost of parabolic trough energy generation, a focus has been the development of advanced heat transfer fluids that operate at a higher temperature than the present fluids, greatly increasing the efficiency of the cycle. This development is linked to the development of some key technology components, such as collectors.

 

Currently, Medors Solar is developing a test loop which will evaluate the use of certain molten salts as the heat transfer fluid. This allows it to operate at 500 º C. This project is being funded by the DOE.

 

Medors Solar is doing critical work with the development of advanced fluids that work at higher process temperatures, improving the cycle efficiency without penalizing other important parameters that could penalize the cost or the plants’ own energy consumption. To support this, collaborative partnership agreements have been created with major research centers in this field worldwide.

 

- Direct steam generation

 

Direct steam generation technology in parabolic trough plants eliminates the need for an intermediate heat transfer fluid in the solar field. The water flows through the tubes and absorbs the reflected energy, then goes through a state change from liquid to saturated steam and then to superheated steam.

 

The main advantage of this technology compared to the existing commercial plants that use thermal oil as the heat transfer fluid is that it eliminates the maximum temperature limitations, thus increasing system efficiency.

 

Medors Solar has the largest parabolic trough direct-steam generation pilot plant. The primary output of Steam at temperatures up to 140°C and pressures up to 10 bar. The captured heat energy is converted to steam which can be used for
