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.
Actually These "big smokestacks" of power plants are not smokestacks that emit exhaust gases as we understand them. 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 to cool in order toensure the smooth running of electricity production. 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 and then vents 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 and diamond shapes. 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.
In summary, we can see that the big chimney of the power plant does not actually cause much pollution nor does it affect everyone's health. So you can rest assured that you don't have to worry too much, even if you live nearbymite of a power plant, because this big chimney that everyone is worried about is actually one of the most efficient and energy-generating devices 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. Qilin 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 to be a benevolent and auspicious beast.
