Vol 2 Chapter 2073: Boiled water changed

Molten salt tower solar thermal power station, as the name suggests, is actually using molten salt for solar thermal power generation. Its main components are potassium nitrate and sodium nitrite. The form of these salts is very stable, and it can be used between 290 degrees and 565 degrees. Maintain a flowable molten state.
Relying on thousands or even tens of thousands of large mirrors (heliostats) around the heat collection tower, the sunlight is concentrated on the heat collection tower to generate high temperature, so that the molten salt delivered here is heated to 565 degrees, and then it is compressed by the pump. It is transported to a high temperature tank for storage.
When power generation is needed, the compression pump will send the molten salt material stored in the high temperature tank to the steam chamber, and then start to boil the water. The boiling point of water is only one hundred degrees, so it will generate heat after absorbing heat. Steam, the steam drives the steam turbine, and the steam turbine is directly connected to the generator to generate electricity.
When the temperature of the molten salt used for boiling water is about 290 degrees, the system will control the compressor to transport it to the low-temperature storage tank for storage, and then wait to be transported to the collector tower again to collect heat.
In fact, to put it bluntly, it is to use thermal energy to boil water, then drive the steam turbine to rotate, and drive the generator to generate electricity.
That's right, it boils water, even the most advanced nuclear power plants boil water in essence. Not to mention the thermal power station that currently supplies half of the country with electricity, which also boils water.
There is also a geothermal power station, which also boils water to generate electricity.
These four types of power stations all boil water, but the energy used is different. The thermal power station mainly uses coal, which is the main power generation of thermal power stations. In addition, there are few oil and natural gas, biogas and other biofuel power generation, but only a few. But no matter what, thermal power plants also bring serious pollution problems while providing electricity.
Although the emission technology of thermal power plants has been improving, the emission has continued, and even more serious air pollution problems have occurred.
The geothermal power station actually uses geothermal heat to generate electricity directly. To put it simply, a power station is built on some high-temperature hot springs, and the high-temperature hot water in the hot springs is directly pumped up to drive the steam turbine to rotate and drive the generator to generate electricity. This can be regarded as a kind of clean energy and does not require much consumption, but the conditions are relatively harsh, and it must have suitable geothermal resources, so it is very rare.
Nuclear power plants, as the name implies, use nuclear reactors to generate electricity. This is also a relatively clean energy source at present, and it is also the main energy source on the earth in the future. It should be said that this is the most efficient among the four types of water-fired power generation, and the power generation is also the largest, which is quite a lot.
However, the disadvantage is also fatal, that is, there is a certain risk. Once the problem occurs, it will bring serious environmental pollution. For example, a nuclear power plant in Japan was damaged due to earthquakes and tsunamis, which eventually polluted most of the world's oceans.
The last is the treatment of nuclear waste. At present, human technology has not been able to carry out harmless treatment, and it can only be carried out by deep burial. Drill a hole several hundred meters and several kilometers deep and bury it in the ground to reduce pollution to the ground.
Even this is a very responsible and safer way for many countries. There are also some rogue countries, in order to reduce the processing cost of these nuclear wastes, they actually sank directly to the bottom of the sea.
Who knows if these nuclear waste tanks will be damaged due to seawater corrosion, submarine volcanic eruptions, pressure, etc., which will cause these wastes to leak and pollute the ocean.
But people don't seem to care. After all, in the last century, they threw dozens of eggs and fried fish like this in the ocean. It is said that Godzilla in the comics and film and television dramas that are popular all over the world is derived from the radiation mutation produced by these eggs.
I don't know if the reality will appear, who knows.
The molten salt tower solar thermal power station is a new clean energy power generation method, which is usually compared with photovoltaic power stations. After all, the two are very similar, both use solar energy, and whether it is a photovoltaic panel or a fixed mirror, the shape is actually similar, and both are clean energy.
However, compared with photovoltaic power plants, which are more limited and depend entirely on the sky, the power generation is unstable and cannot be continuously output. Molten salt tower solar thermal power plants can store heat through molten salt substances. , so its power output is very stable, and it is not subject to day and night changes and weather changes. It is a very ideal, efficient, and low-cost clean energy.
In fact, Wu Hao and the others have built several new super energy storage power stations on the base to store the electricity generated by these photovoltaic power stations for reasonable deployment. However, this kind of super energy storage power station is expensive to build, and the operating cost is relatively high.
The molten salt tower CSP station is relatively low in overall construction cost and operation cost, so it is very suitable for large-scale application.
Of course, this molten salt tower solar thermal power station also has some shortcomings or disputes. That is, it creates light pollution. Thousands of meters or even tens of thousands of mirrors are concentrated on the heat collecting tower, which will produce a bright spot that is much brighter than the sun. This bright spot can be seen clearly for tens of hundreds of kilometers, and even a little dazzling. It is even said that it can be seen on the space station.
In addition, the entire molten salt tower CSP station covers a huge area. The temperature of the light concentrated by these mirrors is very high, which will directly burn or even scorch the birds passing by. Therefore, the surrounding area of ​​the molten salt tower CSP station will be There are many dead birds, so it has been criticized by many environmentalists.
However, this place belongs to the desert next door to protruding ~EbookFREE.me~ There are fewer birds, and the impact of nature is relatively small.
In addition, in order to prevent birds from approaching, a low-frequency generator will be installed in the molten salt tower solar thermal power station. This low-frequency sound cannot be heard by humans, but birds are very sensitive to it. With this low-frequency generator, birds don't come close.
This kind of low frequency generator can be regarded as a little gadget they made, and it has been installed on the airport. After all, the airport is also a place that is very afraid of birds, so in order to protect the safety of the aircraft, it is also to protect these birds, so the technicians also installed this low-frequency generator in the airport.
At present, this technology and related products have been tried out in dozens of civil and military airports in China and have achieved very good results. After passing the relevant license from the civil aviation management department, it will be extended to other airports for use.
In addition to airports, this low-frequency generator can also be used in some other fields, such as buildings, to avoid bird habitation, so as to maintain the plot of the building's façade. The façades of many buildings are due to the habitation of birds, resulting in a large number of bird identifications, contamination of surfaces, and sanitation and epidemic problems.
