Solar Collectors - Fresnel Collector LF-11

The Fresnel Collector is a linear concentrating, solar thermal collector optimized for industrial applications. It can provide heat at up to 400°C and operate with pressures of up to 120 bars. Besides being operated with water, thermal oil or high-temperature glycol, it can also generate steam directly. Due to its modular design, the system can be scaled up from a 500  kW to 30 MW.

How Does A Fresnel Collector Work?

How Does A Fresnel Collector Work

Direct solar radiation is reflected on several rows of single-axis tracking mirrors on to a stationary receiver. This consists of a highly efficient vacuum tube with selective coating. The heat is collected in this absorber tube and fed to the application by means of a heat transfer medium. A part of the sun light reflected by the primary mirrors hits one of the secondary mirrors positioned above the absorber and is reflected from there on to the absorber.
