What is a parabolic trough collector?

Parabolic trough collectors (PTCs) have a common concentration ratio above 10 and lesser than 100, which is considered as “medium concentration” . To realize energy conversion, concentrating technologies require external components, which are generally related to fluid transport or solar tracking, and so they are considered active.

Which axis should a parabolic trough collector be oriented?

The tracking axis is typically oriented north–south for commercial application, as this results in the best output over the year in the typical latitudes of PTC application. Typical dimensions of a PTC are given in Table 1 and illustrated in Fig. 1. Main components of a parabolic trough collector module are the curved mirror and the absorber tube.

Do solar Termal power plants have large-aperture parabolic-trough collectors and SCO2?

How does a trough reflector work?

The cylindrical trough shape of the reflecting surface with parabolic section of the mirror shape has the ability to concentrate the incident sunlight onto an absorber tube in the focal line of the collectors. Typical width of such PTC is 0.5–10 m, and the typical concentration factor is in the range of 50–100.

What is the concentration factor of a trough collector?

The concentration factor is the ratio between the collection area and the receiver area, so it is a dimensionless geometric factor having a value greater than 1 for concentrating technologies. Parabolic trough collectors (PTCs) have a common concentration ratio above 10 and lesser than 100, which is considered as “medium concentration” .
