Concentrator solar parabolic trough collector for solar thermal
PT-3O:
The predominant CSP systems currently in operation are linear concentrators using parabolic trough collectors. Receiver tube is positioned along the focal line of each parabola-shaped reflector. Tube is fixed to mirror structure and the heated fluid-either a heat-transfer fluid or water/steam-flows through and out of the field of solar mirrors to where it is used to create steam (or, for the case of a water/steam receiver, it is sent directly to the turbine).
Currently, the largest individual trough systems generate 80 megawatts of electricity. However, individual systems being developed will generate 250 megawatts. In addition, individual systems can be collocated in power parks. This capacity would be constrained only by transmission capacity and availability of contiguous land area.
Trough designs can incorporate thermal storage. In such systems, the collector field is oversized to heat a storage system during the day that can be used in the evening or during cloudy weather to generate additional steam to produce electricity. Parabolic trough plants can also be designed as hybrids, meaning that they use fossil fuel to supplement the solar output during periods of low solar radiation. In such a design, a natural-gas-fired heater or gas-steam boiler/reheater is used. In the future, troughs may be integrated with existing or new combined-cycle natural-gas- and coal-fired plants.
Main Equipment:
Parabolic trough solar collector is mainly composed of concentrated part, transmission system, heating unit and control system, adopts columnar parabolic design, tracking the sun through parabolic trough concentrate collector, make direct sunlight gathered in receiver tube surface, to heat the heat-transfer fluid, and then in thermodynamic cycle system. In the thermodynamic system, Parabolic trough concentrating collectors are connected by way of series and parallel, and through the modular layout form collection hot field.
Adopts north-south horizontal axis design, effectively improve the collector heat gains. Ultralimit mechanical structure design, collector can achieve wind speed ≤ 7m/s, tracking precision is 0.1°; Gust wind speed in any state ≤ 20m/s, collector is not damaged. Stop protecting state, down wind speed ≤ 32m/s, collector is not damaged
