Can nuclear power plants replace thermal power plants and effectively control smog?

Self-supplied coal-fired boilers and domestic coal (including heating) in various factories are the main source of coal pollution, and about 40% of coal is used in power plants, accounting for only 5% of coal pollution. Even if nuclear power completely replaces thermal power, it will have little effect on solving smog. For coal-fired pollution, centralized is better than distributed for supervision and governance; Even if these facilities are not on the plant, the necessary coal treatment in the power plant, such as grinding the coal mill into pulverized coal, and the continuously improved boiler is more fully burned, which is less polluting than the distributed self-matching coal-fired boiler.

Of course, I support nuclear power and hydropower. Even from an environmental point of view, from an economic point of view, hydropower and nuclear power are quite good. <>

Smog has already covered most of China, and ** has long planned to be ruthless against coal power. However, the purpose of ** is also very clear, not to kill the industry, but just to remediate pollution. Therefore, the coal power industry takes advantage of this potential benefit and engages in consensus with the best people:

Don't kill me, I'll get rid of pollutants to death. So they spent a lot of money to buy technology and engage in technology. Therefore, on the basis of the ultra-strict standards set by the state, each power generation group has formulated more stringent emission standards within itself, and put forward slogans such as "ultra-low emission" and "near-zero emission".

Therefore, those who are familiar with the industry can see that the degree of investment in emission reduction measures of thermal power is far from comparable to that of steel mills, private steel plants, chemical plants, and private chemical plants. On the one hand, it is due to the nature of state-owned enterprises, and on the other hand, it is due to the self-help of the industry. It is not these power generation companies that are forced to reduce emissions, but these companies make choices on their own initiative after considering various factors.

Because in fact, the power of nuclear radiation is very great, far greater than fire and electricity.

Because in fact, the pollution of nuclear power plants is very large, and it is a very high-risk thing after all.

Because nuclear power plants emit nuclear radiation, the pollution is very serious.

Many people have never been to a thermal power plant and are not aware of China's thermal power emission standards. When many people see white smoke coming out of the cold water towers and chimneys of thermal power plants, they shout that it is polluting.

If you've been to a thermal power plant, conducted field research, and studied the emission standards of thermal power plants at home and abroad, then you won't associate smog with thermal power plants.

This is because China's thermal power emission standards are the most stringent. The "white smoke" coming out of the chimney is mainly composed of water vapor and some carbon dioxide, and the pollutants are very few.

By 2020, the vast majority of China's thermal power plants will achieve ultra-low emissions, that is, 5mg of dust, 35mg of sulfur dioxide, and 50mg of nitrogen oxides. This is a quarter of the emission standards of developed countries in Europe and the United States. (The standard is for the United States, but for the European Union).

More than 40% of China's coal is used for power generation, with an average of 78% in Europe and the United States, and 93% or more in the United States. Thermal power emissions are clean and have little impact on the environment (now it is mainly the impact of carbon dioxide, and thermal power plants have already begun to pilot carbon dioxide capture). A large part of China's coal is used for other industrial and private coal burning, and the utilization rate is low, and there are no complete environmental protection facilities, which is one of the root causes of smog.

There is a good saying that if all of China's coal is burned to coal-fired power plants, there will be no smog. <>

Generations of electric power practitioners have worked hard for the cause of thermal power, and we ask everyone to face up to thermal power and the fruits of their labor. The state is also adjusting the industrial structure, encouraging renewable energy, reducing the production capacity of thermal power, "large on the pressure on the small", replacing small thermal power with high-parameter, high-efficiency, and large-capacity thermal power, reducing coal consumption for power supply, and reducing carbon emissions. But everything has a process and it takes time.

Nowadays, the emissions of thermal power plants are actually very low, and they are getting closer and more advanced, and the large thermal power plants I have been to are similar to parks, and the ponds are full of goldfish. In fact, those who engage in nuclear power should not be confused by this question, if ordinary people do not support thermal power, most of them do not support nuclear power either. The infighting in domestic nuclear power enterprises is very serious, and there will be no situation where nuclear power dominates and boycotts thermal power, or there will be no national nuclear technology.

In China, there are only a few plant sites, a few units, and several nuclear power enterprises are fighting for each other, but it is better to solve the problem of infighting first and then talk about the development of nuclear power. The development of nuclear power does not need to target thermal power, but to do a good job of popularizing and explaining science to the people. The impact of thermal power on the environment is so small, nuclear power people are reluctant to understand, so how to explain to the people who talk about nuclear discoloration that nuclear power plants also have a small impact on the environment?

If you don't want to replace it, you have to redesign thermal power generation, and you have to make thermal power generation emission-free

That's for sure, because there is no better alternative, both qualitatively and quantitatively!

Ordinary people will never support nuclear power. Supported. Only specialists.

They don't support nuclear power, they don't have anything to eat. This pair of contradictions. People.

and the contradiction of experts. If you don't believe me, just put the nuclear power plant. Security experts are near their homes, and you see that he agrees or disagrees.

Nuclear tests could have been carried out back then, but nuclear power plants couldn't?! Nuclear energy is definitely going to be discovered before there is no better energy substitute!!

Hello, the generation of haze is mainly due to the emission of air pollutants in the region, and the formation of pollutants after a long period of accumulation. The main sources of pollution include coal-fired thermal power projects, chemical and petrochemical projects, building materials projects, and motor vehicle exhaust emissions. Haze has a great impact on ambient air quality, and at the same time, it also endangers people's health and can easily lead to a variety of respiratory diseases.

The state realizes that the current haze pollution control work has reached the point of urgency, and the Ministry of Environmental Protection has formulated various prevention and control policies and measures, such as the introduction of a new "Environmental Protection Law" required to be implemented on January 1, 2015, and increased environmental impact assessment and environmental supervision; The "Measures for the Joint Prevention and Control of Air Pollution" was promulgated, which requires that "no new coal-fired power plants shall be built in the built-up areas, planning areas and suburbs of large and medium-sized cities" and "the installed capacity of new coal-fired power plants shall not be less than 300,000 kWh", and the newly revised "Air Pollution Prevention and Control Law" requires the Beijing-Tianjin-Hebei, Yangtze River Delta, Pearl River Delta and other regions to be implemented in advance and implemented nationwide by 2016; The provisions on nitrogen oxides as the total amount control index in the "Comprehensive Emission Standards for Air Pollutants" have been restored, and so on.

For the thermal power industry, it is both a challenge and an opportunity, and at a small level, if you want to reduce and control the emission of air pollutants from thermal power plants, you need to improve the production process, update the equipment, use cleaner energy, and improve the removal rate of pollutants by improving the desulfurization, destocking, and dust removal facilities. Investments in such equipment require a large amount of capital, and cost and efficiency considerations are also required while the current level of electricity prices remains unchanged. In addition, with the country's increasingly strict environmental protection policies, some thermal power plants with insufficient installed capacity will face transformation or be eliminated if they do not increase investment.

In addition to the predicament, it is also a great opportunity for the restructuring and layout of China's energy structure, coal is not inexhaustible, and it is necessary to develop bioenergy and wind energy under the condition that environmental conditions permit. Coal-fired power plants in many regions have increased wind power generation, reducing the use and dependence on coal, while the overall power generation and economic benefits have been much improved. The development of clean energy is an important condition for China's sustainable development in the future, and many policies in China are often actively or passively generated due to the occurrence of one or more social events, and environmental pollution incidents are one of the important inducements.
