Trough Solar Assisted System

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.

What is a parabolic trough (PT)?

In CSP technologies, a parabolic trough (PT) is able to be regarded as a perfected technology under CSP plants, which has also demonstrated its economic viability 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17. For instance, the PTPPs are capable of reaching temperatures approaching 395 °C 18.

How efficient is a solar-assisted gas turbine?

Ferraro et al. proposed a thermal model to analyze the thermal behavior of a solar-assisted gas turbine with two modes of operation: with constant inlet temperature/variable air flow rate and constant air flow rate/variable inlet temperature, all of them with and without reheating achieved an annual average efficiency of 17.8%.

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” .
