Due to their ability to generate electricity according to demand, solar thermal power plants are becoming increasingly important for a future, climate-neutral energy system. However, further measures are required to accelerate the spread of the technology:
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.
Harnessing solar energy for electric power generation is one of the growing technologies which provide a sustainable solution to the severe environmental issues such as climate change, global warming, and pollution. This chapter deals with the solar thermal power generation based on the line and point focussing solar concentrators.
The operation of solar thermal power plants is based on obtaining heat from solar radiation and transferring it to a heat carrier medium, which is generally water. To raise the water temperature to the desired high levels, maximum solar radiation must be concentrated at one point.
In this paper solar tower structure is designed for a 50MW solar thermal power plant. A review of different types of towers used in solar thermal power plant is included at the start. Design process of tower structure is started by designing a tower structure based on the height requirement obtained from ray trace analysis.
To raise the water temperature to the desired high levels, maximum solar radiation must be concentrated at one point. In this way, temperatures of 300ºC to 1000ºC can be obtained, which will be used to generate steam. The higher the temperature, the greater the thermodynamic performance of the solar thermal power plant.
Since steam turbines can only be operated economically above a certain minimum size, today’s solar thermal power plants have rated outputs in the range of 50 to 200 megawatts. The main difference to a conventional steam power plant is the solar field, which supplies the heat for the steam generator.
Due to their ability to generate electricity according to demand, solar thermal power plants are becoming increasingly important for a future, climate-neutral energy system. However, further measures are required to accelerate the spread of the technology:
