Compact linear Fresnel reflector

(重定向自Fresnel reflector)
Fig.2: Incident solar rays are concentrated on insulated steam tubes to heat working thermal fluid
Fig.3: CLFR solar systems alternate the inclination of their mirrors to focus solar energy on multiple absorbers, improving system efficiency and reducing overall cost.

A compact linear Fresnel reflector (CLFR) – also referred to as a concentrating linear Fresnel reflector – is a specific type of linear Fresnel reflector (LFR) technology. Linear Fresnel reflectors use long, thin segments of mirrors to focus sunlight onto a fixed absorber located at a common focal point of the reflectors. These mirrors are capable of concentrating the sun’s energy to approximately 30 times its normal intensity. This concentrated energy is transferred through the absorber into some thermal fluid (this is typically oil capable of maintaining liquid state at very high temperatures). The fluid then goes through a heat exchanger to power a steam generator. As opposed to traditional LFR’s, the CLFR utilizes multiple absorbers within the vicinity of the mirrors.
