Concentrating solar power CSP systems


Concentrating solar energy (CSP) technologies utilize mirrors to concentrate (focus) the sunlight's light power and transform it into temperature to generate vapor to operate a vehicle a turbine that yields electric power.

CSP technology utilizes concentrated sunshine. CSP flowers create electric power using mirrors to concentrate (focus) the sunlight's power and convert it into high-temperature heat. That heat will be channeled through a conventional generator. The flowers include two parts: one that gathers solar energy and converts it to warm, and another that converts the warmth power to electricity. A quick video clip showing just how concentrating solar powered energy works (using a parabolic trough system as an example) can be acquired from the division of Energy Solar Energy Technologies Web site.

Inside the usa, CSP plants have now been operating reliably for longer than 15 years. All CSP technical techniques require huge places for solar power radiation collection when regularly create electricity at commercial scale.

CSP technology utilizes three alternative technical techniques: trough methods, energy tower methods, and dish/engine systems.

Trough Techniques

  • Trough systems utilize big, U-shaped (parabolic) reflectors (focusing mirrors) that have oil-filled pipelines working along their particular center, or focus, as shown in Figure 1. The mirrored reflectors are tilted toward sunlight, while focusing sunshine on the pipelines to heat the oil inside to as much as 750°F. The hot oil will be accustomed boil liquid, making steam to perform traditional steam turbines and generators.

Power Tower Techniques

  • Power tower systems also called central receivers, use numerous large, level heliostats (mirrors) to track the sunlight while focusing its rays onto a receiver. As shown in Figure 3, the receiver sits above a tall tower by which concentrated sunlight heats a fluid, such molten sodium, because hot as 1, 050°F. The hot substance can be used instantly to create steam for electricity generation or kept for later use. Molten salt keeps heat efficiently, so it could be saved for several days before becoming became electrical energy. That means electrical energy are produced during times of top need on cloudy days and sometimes even a long time after sunset.

Dish Motor Systems

  • Dish/engine systems utilize mirrored meals (about 10 times larger than a garden satellite meal) to concentrate and concentrate sunshine onto a receiver. As shown in Figure 5, the receiver is installed at focus of meal. To fully capture the most of solar technology, the dish set up tracks the sun's rays throughout the sky. The receiver is built-into a high-efficiency "external" combustion engine. The motor has slim pipes containing hydrogen or helium gas that operate over the outside the engine's four piston cylinders and open into the cylinders. As concentrated sunlight drops regarding the receiver, it heats the gas in tubes to extremely high temperatures, which causes hot gas to expand within the cylinders. The expanding fuel drives the pistons. The pistons turn a crankshaft, which pushes a power generator. The receiver, motor, and generator comprise just one, incorporated installation mounted in the focus regarding the mirrored meal.
