Design specification for tower solar thermal power station pdf

How many solar tower modules are there?

Each of the 14 solar tower modules consists of a receiver with a design point (DP) power of 50MWth , a tower, a heliostat field and a thermal storage. A scheme of a module is shown in Figure 1a. The total thermal system power is 700MWth at DP conditions. With the power cycle demand of 291MWth this represents a solar multiple of 2.4.

What is a solar thermal tower power plant?

Central receiver systems such as solar thermal tower plants can reach higher temperatures and therefore achieve higher efficiencies. In solar thermal tower power plants, hundreds or even thousands of large two-axis tracked mirrors are installed around a tower.

How does a solar tower power plant work?

In a solar tower power plant, biaxially tracking mirrors, referred to as heliostats, direct the solar radiation onto a central receiver mounted on a tower. A heat transfer medium, usually molten salt or alternatively water / steam or air, absorbs the energy there and transports it to the thermal storage system and to the power plant circuit.

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 are the location requirements for solar thermal power plants?

The location requirements for solar thermal power plants are comparatively low. Stony, rocky and gravel deserts with little vegetation are suitable, as are grasslands, scrublands and savannahs, for which there are practically no other economic uses, and which are available is almost unlimited quantities for this application in the Sun Belt.

What is the thermal power output of a solar tower?

Due to constraints of the test platform in the solar tower test facility, which is located about midway up the tower, a thermal power output of up to 500kWth is expected. Nearly 70h of solar testing were carried out, and receiver outlet temperatures up to 965°C (average) were achieved .
