Figure 1 shows a process flow diagram that is plants in operation today.
The solar system is comprised of the solar reflectors, solar receiver, and heat exchangers needed to transfer the collected solar energy to the working fluid of the power block.
In the trough system, sunlight is concentrated by about 70–100 times on the absorber tubes, achieving operating temperatures of 350 to 550°C. A heat transfer fluid (HTF) pumped through the absorber
Although many solar technologies have been dem-onstrated, parabolic trough solar thermal electric power plant technology represents one of the major renewable energy success stories of the last two
Imagine giant metallic "sunflowers" tracking daylight across the sky – that''s essentially what solar trough systems do. These parabolic-shaped mirrors focus sunlight onto receiver tubes containing thermal
Imagine using sunlight to power entire cities – not with solar panels, but with mirrors that create enough heat to generate steam for electricity. That''s exactly what trough solar thermal power generation
Parabolic trough is the linear-focus collector, which consists of a cylindrically curved parabolic mirror, which reflects the sunlight onto a tubular receiver positioned in the focus line of the parabola.
Parabolic trough power plants consist of large fields of mirrored parabolic trough collectors, a heat transfer fluid/steam generation system, a power system such as a Rankine steam turbine/generator,
On sunny days, oil in the receiver tubes collects the concentrated solar energy as heat, and on cloudy days it is heated with natural gas. The hot oil is then pumped to an electric power generation system
