A linear concentrating device called a parabolic trough collector (PTC) consists of long mirrors with a parabolic form and a receiver tube positioned along the parabola’s focal axis. DNI is focused onto the receiver tube, where the HTF absorbs solar radiation
.A parabolic trough is a form of solar thermal collector that has a polished metal mirror lining and is straight in one dimension and curved as a parabola in the other two. Sunlight that reaches the mirror perpendicular to its symmetry plane is focused along the focal line, where heated objects are placed.
Food is placed at the focal line of a trough in a solar cooker, for instance, and cooked when the trough is directed so that the Sun is in its symmetry plane. A fluid-filled tube extends the length of the trough at its focal line for additional uses. The fluid is heated to a high degree by the energy of the sunlight as it is focussed on the tube.
The heated liquid can be routed to a heat engine, which can then utilise the heat energy to power machinery or create electricity. The most popular and widely recognised variety of parabolic trough is this solar energy collector.
The Global parabolic trough collector market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The technology of parabolic trough collectors has advanced, and in the past years, a lot has been learned. For collectors, there are still no industry norms, though. Standards are essential for designing collectors that can withstand wind loads.
Since not all collectors are created using the same methods, they each have unique design requirements and wind survival capacities. Several plants have also been constructed in areas where it appears that the actual wind conditions may have been worse than those anticipated during design.
There have been a number of major wind-related collector failures, and these have involved some of the more seasoned collector vendors’ designs. For determining the design wind conditions at a location, the industry needs better design standards and methods.
Even while collector optical certification has made tremendous strides recently, most plants still don’t seem to have a firm grasp on the actual optical performance of their solar fields. The new tools that are starting to become accessible in this field could be advantageous for new initiatives.
