Solar Tower

Solar towers are huge constructions that are created by many segmented mirrors close to the ground and a great receiver placed centrally in a high position. The tower is used in power production applications and usually coupled to highly efficient power blocks. In 2010, Alexopoulos and Hoffschmidt (2010) performed a preliminary work about the possible operation of a solar

Concentrating Receiver Systems (Solar Power Tower)

Solar thermal tower power plants with nearly planar mirrors focus solar radiation and direct it onto a receiver, which is located at the top of a tower. Very high temperatures in the receiver, resulting from this concentrated solar radiation, enable generation of power plant process steam. The steam can be expanded in a steam turbine and

Can solar thermal power plants provide electricity to 100 million people?

By concentrating solar energy with reflective materials and converting it into electricity, modern solar thermal power plants, if adopted today as an indispensable part of energy generation, may be capable of sourcing electricity to more than 100 million people in the next 20 years [source: Brakmann].

Solar power tower

A solar power tower is a system that converts energy from the Sun - in the form of sunlight - into electricity that can be used by people by using a large scale solar setup. The setup includes an array of large, sun-tracking mirrors known as heliostats that focus sunlight on a receiver at the top of a tower. In this receiver, a fluid is heated and used to generate steam.

Solar updraft tower

Schematic presentation of a solar updraft tower. The solar updraft tower (SUT) is a design concept for a renewable-energy power plant for generating electricity from low temperature solar heat. Sunshine heats the air beneath a very wide greenhouse-like roofed collector structure surrounding the central base of a very tall chimney tower. The resulting convection causes a

Thermodynamic cycles for solar thermal power plants: A review

Solar thermal power plants for electricity production include, at least, two main systems: the solar field and the power block. Regarding this last one, the particular thermodynamic cycle layout and the working fluid employed, have a decisive influence in the plant performance. In turn, this selection depends on the solar technology employed.

Solar thermal power plants

In solar thermal tower power plants, hundreds or even thousands of large two-axis tracked mirrors are installed around a tower. These slightly curved mirrors are also called heliostats; a computer calculates the ideal position for each of these, and a motor drive moves them into the sun. The system must be very precise in order to ensure that

How do solar thermal power plants work?

Solar thermal power plants are electricity generation plants that utilize energy from the Sun to heat a fluid to a high temperature. This fluid then transfers its heat to water, which then becomes superheated steam. This steam is then used to turn turbines in a power plant, and this mechanical energy is converted into electricity by a generator.
