    Parabolic Trough Collector - an overview ScienceDirect

    A parabolic trough collector (PTC) is a linear concentrating system made of long, parabolic-shaped mirrors and a receiver tube placed along the focal axis of the parabola. DNI is concentrated onto the receiver tube (as illustrated in Fig. 16.8), where solar energy is absorbed by the HTF.A glass envelope is often placed around the HCE to limit convection losses and 50332AL Parabolic Mirror - Newport The 50332AL Off-Axis Replicated Parabolic Mirror is 1.50 inches in diameter, with an effective focal length of 8.00 inches, and coated with Protected Aluminum. These standard off-axis parabolic mirrors are circular segments from one side of a full paraboloid. The focal point is displaced from the mechanical axis, giving full access to theParabolic trough - Wikipedia A parabolic trough is a type of solar thermal collector that is straight in one dimension and curved as a parabola in the other two, lined with a polished metal mirror.The sunlight which enters the mirror parallel to its plane of symmetry is focused along the focal line, where objects are positioned that are intended to be heated.In a solar cooker, for example, food is placed at Solar Spark Lighter and Survival Tool : Health It is a stainless steel parabolic mirror, like the one used to light the Olympic torch.
