LINEAR FOCUSING FACILITIES

THE FRESDEMO LOOP

The FRESDEMO loop is a “Linear Fresnel  concentrator” technology pilot demonstration plant. This 100m-long, 21-m-wide module has a primary mirror surface of 1,433 m2, distributed among 1,200 facets mounted in 25 parallel rows spanning the length of the loop. This collector loop is designed for direct steam generation at a maximum pressure of 100 bar and maximum temperature of 450º.

This pilot facility is presently connected to the piping system of the PSA DISS plant from where it is supplied with solar steam at different pressures and temperatures for testing in the three working modes: preheating, evaporation and superheating.
