Electricity generation methods include: thermal power generation, hydroelectric power generation, nuclear power generation, wind power generation, geothermal power generation, etc.
Power generation refers to the production process of using power generation devices to convert raw energy such as water energy, thermal energy from petrochemical fuels (coal, oil, natural gas), nuclear energy, etc. .in electrical energy.
Electricity generation is used to meet the needs of various departments of the national economy and people's lives.
Nowadays, fossil fuels are still used as the main form of electricity generation, but fossil fuel resources are not plentiful and are becoming increasingly depleted. Human beings have graduallystarted using solar energy, wind energy and geothermal energy. , ocean energy and other energy sources to generate electricity.
Which mythical beast from ancient China can both breathe fire and generate electricity
Solid and tall chimneys can be seen all around us. Generally, certain factories, boiler rooms or power plants are the most common. The power plant's "big chimney" is different from other chimneys and emits a large amount of white "smoke" into the air every day. Many people think that if so much smoke is emitted every day, it's no wonder. that air quality is poor. If you know what these “big guys” do, you will feel bad.
In fact These "big chimneys" of power plants are not chimneys that emit exhaust gases as we understand themns. Its name is cooling tower. The power plants we usually see today are essentially thermal power plants. When producing thermal power, the unit requires a large amount of cooling water for cooling to ensure smooth power generation. However, without these cooling towers, a large amount of water would be consumed every day for heat dissipation and cooling.
So why do cooling towers emit “smoke”? After cooling the device with cold water. Water vapor is produced when the water in the cooling tower heats up. Another function of the cooling tower is to recycle water without wasting water resources. This uses the difference in air density inside and outside the cooling tower to form a pressure difference.on, then ventilate it. Most of the water vapor and air cooled to form water droplets and fell into the tank. The water vapor which did not have time to cool escaped from the "big chimney",forming what we see. The “smoke” is actually just water vapor.
So why is it designed like that? Like a big speaker played backwards! In fact, previous power plants also had cooling towers. At the beginning of the design, all shapes were tried, including straight shapes and diamond-shaped ones. I finally settled on this big speaker look. That’s also a lot of factors to take into account. Since power plant cooling towers are usually built at a height of around 160 to 200 meters, this style is the most economical and has a stable structure.
InSummary, we can see that the big chimney of the power plant does not actually cause much pollution and also does not affect everyone's health.Kang. So you can rest assured that you don't have to worry too much, even if you live near a power plant, because that big chimney that everyone is worried about is actually one of the energy-producing devices. most efficient and energy-efficient energy produced by paying attention to environmental protection.
Fire-breathing and electric beast: Thunder Lord riding a unicorn.
Qilin, also known as "Qilin", the male is called Qilin and the female is called Lin, or "Lin" for short. Kirin is an animal recorded in ancient Chinese books. Along with the phoenix, the turtle and the dragon, it is called the “Four Spirits” and constitutes the mount of God. The ancients considered the unicorn a benevolent animaland auspicious. In fact, the giraffe was often considered the prototype of the unicorn and was often used to describe exceptional people.
Judging by its external shape, it combines a dragon's head, antlers, lion's eyes, tiger's back, bear's waist, snake's scales, horse's hooves and an oxtail, which is an auspicious treasure. According to the description in ancient books, its body is like a 麟, which can also be written as a deer, which refers to a deer in ancient books; its tail is like a cow; his hooves are like a horse; has a pair of horns. It was considered by the ancients as a sacred and benevolent beast. Qilin has longevity and can live for two thousand years. He can breathe fire and his voice is like thunder. “There are three hundred and sixty hairy worms, but the unicorn is the longest.”
