What is a solid particle solar receiver (SPSR)?

Solid particle solar receiver (SPSR) is the key equipment to absorb the concentrated solar flux, and its thermal performance is remarkably affected by receiver system designs, particle flow characteristics, and properties of solid particulate materials.

Can solid particles be used in solar receiver technology?

Initially, the application of solid particles in solar receiver technology is to obtain high temperature gas, instead of high temperature solid particles. In this concept, the solid particles are enclosed in a solar receiver and transfer the absorbed heat to the inlet gas stream.

How do solid particles absorb solar radiation?

The solid particles are suspended from a distributor located at the bottom of the receiver under the action of the drag force of the fluidized air. They absorb solar radiation indirectly through the heated walls of the receiver and exit from the top of the receiver . Fig. 12. Working principle of fluidization phenomena .

What is a central receiver concentrating solar power plant?

This overview will focus on the central receiver, or “power tower” concentrating solar power plant design, in which a field of mirrors - heliostats, track the sun throughout the day and year to reflect solar energy to a receiver that absorbs solar radiation as thermal energy.

What is a power tower concentrating solar power plant?

In summary, the power tower concentrating solar power plant, at the heart of which lies the heliostat, is a very promising area of renewable energy. Benefits include high optical concentration ratios and operating temperatures, corresponding to high efficiency, and an ability to easily incorporate thermal energy storage.

What is concentrated solar power (CSP)?

Concentrated solar power (CSP, also known as concentrating solar power, concentrated solar thermal) systems generate solar power by using mirrors or lenses to concentrate a large area of sunlight into a receiver.
