Solar Steam Generators
In present time, the excessive use of electricity for the minutest of things, has led to a shortage all around the globe. Resources are getting exhausted swiftly and population is increasing on the double. This situation is heading towards a disastrous end and to avert that end solar steam generators have been invented. Solar steam generators, utilizes the solar energy to produce electricity rather than the conventional non-renewable resources. Traditionally, electricity is produced in power plants by the turning of heavy turbines, which are powered by steam produced by the burning of coal, gas or oil. Hence, these power plants emits out unsafe gases in the atmosphere that is causing the global warming.
Solar steam generators are extremely eco-friendly and helps in keeping the air clean and produce maximum electricity. These generators’ popularity is increasing by the day around the sphere, as they work on a renewable source of energy i.e., solar thermal energy. Another factor for increasing acceptability of solar steam generators is that solar energy is absolutely free whereas the price of coal and oil is escalating by the minute.
Solar steam generators consist of a boiler, heliostats, heat transfer fluid and steam turbine. Boiler is the place where the heat is collected from the sun. The spherical mirrors (heliostats) used in the solar steam generators can either be cylindrical parabola or the circular parabola. The former one focuses the sunlight to a line whereas the latter one focuses it to a point. Heliostats, the moveable parabolic mirrors, face automatically towards the sun to absorb the heat of the optimally. The heat transfer fluid can either be water or liquid sodium. When the fluid placed inside the boiler gets heated up by the sun’s heat, it is transferred to the heat exchanger where it gets transformed into steam. Water’s temperature can be raised up to 220 degrees C using the solar steam generators. After 100 degrees C, water converts into steam under very high pressure and this steam is then pushed on to the steam turbine. The pressure of the steam makes it to move in circular motions and thus creates electricity.
Solar steam generators utility is helping people to get access to electricity where there is extreme shortage of it. In distant future, when there’ll be no more fossil fuels to burn that can power the turbine, solar steam generators will be the only solution. Solar steam generators help in protecting the environment as well as the human species from harmful diseases, which are caused due to the deadly fumes and gases released by the conventional power plants. Using solar steam generators from today itself is a step taken towards a secure future. Safeguarding oneself from utter despair, when there’ll be no more resources to burn, is the only priority in everyone’s mind right now. Solar steam generators are being adopted by responsible countries across the globe, which understand the value of non-renewable resources and the harmful effects of their sheer wastage. Solar Panels India offers a list of manufacturers who manufacture steam generators.
