The most usual dilution is extreme (1:3), and cleaning is done using spray bottles, parts washers, pressure washers, and, depending on the size of the turbines, heavy duty spraying from helicopters. The goal is to remove all contamination—including salt and ice—from the blades before they reenter service. This prevents damage that can result in failure of the turbine.
Other options include washing them in-situ by water jets or abrasives, or removing them from service for dry cleaning.
Larger scale cleaning involves use of high-pressure washes and heaters to remove contamination from engine cabs, gearboxes, and other components inaccessible to users. Some facilities have special rooms where large components can be cleaned and restored back to service.
In conclusion, wind power plants must be maintained like any other machine to ensure their continued operation. Maintenance includes regular inspection of electrical and mechanical systems for problems that may lead to downtime. Small issues can become major problems if not corrected promptly; therefore, it is important to maintain wind energy facilities regularly so they can provide clean renewable energy as needed.
Wind Generators use the wind's force on rotating blades to drive a shaft, which in turn drives a generator to produce electricity. The most common type of wind generator is the horizontal-axis wind turbine (HAWT). This design uses two counter-rotating blades to transform wind energy into rotational motion that drives a central hub, which in turn drives an axle that can be used for grinding grain or pumping water. HAWTs were first developed in Denmark in the early 20th century and have been improved upon since then.
Solar power generators use the sun's energy to run turbines, which in turn generate electricity. Solar power generation technologies include solar cells, solar heaters, and solar power towers. Solar cells are capable of converting light energy directly into electrical energy without any other material or component involved. Solar heaters use the energy from sunlight to heat something, such as water or air, which in turn produces steam that turns a turbine to generate electricity. Solar power towers use hundreds of mirrors to concentrate sunlight onto a single point, allowing it to heat molten salt or oil, which in turn drives a turbine to generate electricity.
EXTRACTION OF OXYGEN FROM THE AIR USING A WIND TURBINE There are techniques to separate oxygen from air using fractional distillation, however there are no known successful operations employing wind turbines to extract oxygen from air. Fractional distillation is the separation of a mixture into its constituent elements. The process involves heating and separating the components by boiling point. The vapor produced then condenses back into liquid form for re-use in the process.
Oxygen can be extracted from air using various methods including chemical, physical, and biological. Chemical methods include silver oxide, sodium peroxide, calcium hydroxide, and potassium permanganate. Physical methods include ice crystals, adsorption on solid surfaces, and diffusion through porous materials. Biological methods include plants growing oxygen-producing chemicals in leaves and roots, and bacteria converting carbon dioxide into organic compounds that produce oxygen as a by-product.
Silver oxide is used to produce metallic silver from silver ions. The method is expensive because large amounts of heat are required to drive off the ammonia generated as a by-product. Calcium hydroxide has been used to remove oxygen from air, but it becomes saturated with oxygen very quickly. Potassium permanganate reacts with oxygen to produce water and manganese dioxide. This method is effective for laboratory experiments but not practical for industrial applications.
Plants take up carbon dioxide during the day and release oxygen at night. This is called photorespiration.
