China's coal-fired boiler industry chain has made indelible contributions to the realization of China's industrialization. China is the largest manufacturing country, and China’s second industry’s GDP is far higher than the second-ranking United States. It is a truly world’s largest industrial power. Most of the industrial thermal power depends on coal-fired boilers. China has a total of approximately 470,000 coal-fired boilers, with an average capacity of 3.8 tons. These 470,000 combustion boilers can be said to be the source of the power of Chinese industry. China has a rich and cheap coal reserve, which provides an inexhaustible source of fuel for coal-fired boilers. Without cheap industrial heating power, China's industrialization will not reach such a high level of development. Demonized coal-fired industrial chain. China's coal-fired industrial chain is an industry chain in which China rarely has no foreign investment. Coal mines are either state-owned enterprises or private owners. The majority of manufacturers of boilers are also state-owned enterprises and private enterprises. Foreign-funded enterprises pay attention to eating, and Chinese people often do not pay attention to this issue. Chinese enterprises also pay special attention to the fight for the right to speak, especially those industrialists who are sulking to do things. The treatment of coal miners, the black coals and the smoky chimneys have not given the people a better impression. Without foreign investment, of course, it is easy to be demonized! Do not you see, in the past few years, mainstream economists have demonized the Chinese high-speed rail business, scared to hear China's high-speed rail crisis. Fortunately, the achievements of China's high-speed rail are acceptable to most ordinary people and the plot did not succeed. Other industries have not been so lucky. If China's coal-fired industrial chain requires the rescue of foreign capital, it can avoid being demonized. Only by allowing foreign investors to purchase relevant coal mines and upstream and downstream industries at a low price can they be demonized. This may be a helpless but “win-win†option. In China, as long as foreign industries dominated by foreign capital do not have peace, the automobile industry is also dominated by foreign capital, and even if the emissions of automobiles are higher than coal-fired boilers, even if there are problems with foreign auto manufacturers, it is not large in China. problem. In areas where China's atmospheric environmental capacity has exceeded its limits, such as certain locations in Hebei, it is very correct to restrict and eliminate some coal-fired boilers. In the middle and western regions of the country, many counties have almost no decent industrial enterprises because of restrictions on transportation, talent, and information. The entire county's GDP is only about 1.2 billion yuan. A small number of industries in the central and western regions can only grow in prefecture-level cities or provincial capitals. Only in this way can soft and hard infrastructure such as talents and transportation be allowed to survive in Midwestern enterprises. If these enterprises, which are still relatively small, cannot burn coal-fired boilers and only burn biomass or natural gas, the best option for these companies is to close down. Because the cost of burning biomass is twice that of burning coal, the cost of burning natural gas is three to four times that of burning coal. It is now advocating that China's manufacturing costs have surpassed that of the United States. Flying to the boiler room is not a better match for this paradox? How could medium and small boilers in prefecture-level cities have one or two hundred thousand units? If it is before 2017 Have these boilers stopped all the time, does this not indirectly let China industrialize? Some people may say that the "plan" is to encourage the use of large boilers, banning small boilers, did not say to ban all boilers. This general direction may be correct. However, can each area guarantee that the local centralized industrial park can be completed and put into production before 2017? Not to mention the current economic downswing pressure is increasing, the company's survival is still difficult, and it is even more difficult to relocate. In addition, such large boilers with a capacity of more than 560 tons are surrounded by more than 10 kilometers or even longer steam pipes in industrial parks, and their thermal efficiency is not necessarily high. In particular, there are also many problems with centralized steam supply. In the off-season, if only one or two companies in an industrial park need steam, and dozens of them are not needed, such gas supply costs are also very high. During the peak season, the steam generated may not be enough. The "Program" almost cut off the idea that all young people want to start a business in the manufacturing industry. In general, the small private owner, entrusted with the reform and opening up of the Communist Party, spent twenty to thirty years of energy, engaged in a small factory, and finally closed down, there is no way to do things. To control air pollution, we can't blame the burning boiler The problem of air pollution in China is mainly caused by the improper layout of China's heavy chemical industry. Why is it so severe in northern China? More than a decade ago, we only focused on the sandstorms in Beijing. Since the US Embassy in China focused on smog, the whole nation began to worry about this issue. The unreasonable layout of China's heavy chemical industry can be said to be a major weakness of the Chinese economy. Western unfriendly countries naturally take this thing to enlarge. Air pollution in North China and the Yangtze River Delta region has a lot to do with the excessive concentration of heavy chemical industries in these areas. We see that the air pollution in the central and western regions of Jiangxi and Guizhou is relatively much lighter. The air quality of the industrial-free Tibet Autonomous Region is not worse than that of any developed Western region. The atmospheric environment capacity in North China has far exceeded the limit. Then, what we need to do is to control the company's gas emissions, or to relocate the company to other provinces with a certain amount of environmental capacity. We do not need to use coal-restricting measures in the areas where the industries in the Midwest are left behind. If coal is excessively limited, events like Longmei coal will appear more often. If the artificial demand for coal disappears, the future of coal mines will never have hope. Now the state encourages the transfer of processing trade to the central and western regions. If the same harsh industrial heat power standards are adopted, the costs of the central and western regions will not have obvious competitive advantages over other countries such as Southeast Asia. Industrial coal-fired boilers are not the main culprit of atmospheric pollution. The “Programme†mentioned that the smoke, sulfur dioxide and nitrogen oxides produced by industrial coal-fired boilers account for 33%, 27% and 9% of the total national emissions, respectively. The removal of soot and sulfur dioxide is not technically difficult and the investment is not large. Enterprises can afford it and the environmental protection department can fully supervise it. As for the cost of denitrification devices, high- and medium-sized coal-fired boilers do not necessarily have to be installed. Even installing a denitrification device is much less expensive than burning natural gas. China's environmental protection agencies have made great achievements in sewage treatment. The author saw that the water quality of many rivers in the Yangtze River Delta and the Pearl River Delta was cleaner than that of Germany's Rhine River. Why doesn’t our environmental protection department give a little more patience and a little more confidence to China's coal-fired industry? On what basis does China's large and small industrial coal-fired boilers meet the standards? According to the data of the Ministry of Environmental Protection, the nitrogen oxides generated by automobiles account for 29% of the total emissions in the country. Should we restrict the increase in automobiles? After all, China will add more than 20 million cars each year, and it will need to increase a lot of oil imports every year. It consumes a lot of foreign exchange reserves. The annual emissions of coal-fired boilers are decreasing, while the haze in northern China is increasing. Ten years ago, when China's combustion boilers discharged the most, the haze was much lower than it is today. The chief culprit of smog should be automobile fuel emissions. In San Francisco, the smoke-free industrial city in the United States, the author saw the grey sky in the rolling traffic. According to the calculation in the "Programme", the total power of China's industrial coal-fired boilers is 1.25 billion kilowatts. In China, 20 million new cars are added each year. Calculated with an average power of 100 kilowatts per vehicle, the total power of new cars in China each year is 2 billion kilowatts, which is far more than the total power of 470,000 coal-fired boilers. If the inventory of China's 170 million vehicles is calculated, its total emission power will exceed 17 billion kilowatts, which is more than 13 times the power of coal-fired boilers. It can be roughly estimated that the average daily pollution emission of automobiles is at least three or four times that of coal-fired boilers. China has just signed the "Paris Climate Agreement" to control greenhouse gas emissions. Even if China removes all industrial coal-fired boilers since the founding of the People's Republic of 66 years, it will not be enough to offset the increase in greenhouse gas emissions of new cars each year. To control air pollution, reduce greenhouse gas emissions, and reduce foreign exchange reserves, the right way is to reduce the use of fuel vehicles and aircraft, and vigorously develop high-speed rail and all kinds of rail transit. This is the first choice for a country with a vast territory and a large population. Unrestricted increase in fuel vehicles and the suppression of the use of coal-fired boilers will ultimately abolish China's industrial production capacity. This is wrong. Going to boilers will endanger national economic security The original purpose of the coal-fired boilers was to control atmospheric haze. Perhaps such an approach would affect the economic security of the country. First of all, this has greatly increased the production costs of SMEs. The cost of natural gas is three to four times that of burning coal. In the current era of low-cost oil and gas, the cost of natural gas is still so high. If oil returns to US$150 a barrel, the cost of natural gas will increase significantly. SMEs will collapse in large numbers due to increased energy costs, and the entire country’s economy will fall into crisis. Second, China's coal is inexhaustible. After the coal-fired boilers are banned, they can only be buried underground forever and cannot be used effectively. China will have unemployed millions of coal workers, and the related boiler industry and machinery industry will be greatly hit. China can only import natural gas from abroad, and the source of natural gas from abroad is not stable. Especially in the winter, the entire Northern Hemisphere needs natural gas. When Russian Uncle Putin is in a bad mood, he can stop at any time. The thousands of miles of gas pipelines are also vulnerable to destruction by various armed forces abroad. In short, once China relies on imported natural gas, the fate of China's industrial energy will be given to foreign suppliers. Gasoline prices rise, the Chinese can drive less or not drive; natural gas prices, Chinese companies can't open a job, there is no industrial production, China still depends on becoming a world power? Once again, China's natural gas imports do not simply cost tens of billions of dollars, and hundreds of billions of US dollars in foreign exchange reserves are used to import natural gas. China’s foreign exchange reserves can not spend as little as it can. These foreign exchange reserves mainly belong to foreign-invested enterprises that invest in China. The assets and profits accumulated by foreign-funded enterprises in China have exceeded China’s total foreign exchange reserves. The indirect effect of decarbonization is that the ability of small and medium-sized enterprises to earn foreign exchange through exports, as well as the international competitiveness of cost-sensitive processing trade enterprises, will decline, and the export capacity of Chinese enterprises will decline significantly. The author is very reluctant to see that in 2017, China's exports will decline sharply, and China will enter a balance of import and export and even a deficit era. If such a situation really occurs, it is possible for the renminbi to be forced to depreciate. Because, for the foreign capital to compete for limited foreign exchange will rush to divest from China. Fourth, to de-industrialize the boiler, intentionally or unintentionally matched the United States' "re-industrialization" strategy. While China is making a big push to de-industrialize “de-capacity,†the United States is doing everything possible to implement re-industrialization. The "correct theory of international industrial transfer" advocated by mainstream economists is not believed by the U.S. government. If the U.S. government agrees, why does the U.S. still want to reindustry? Does the United States engage in high technology, engage in finance, and print banknotes? Is it only possible to prove the superficial nature of mainstream economists? Although overall global productivity is enough to allow the majority of the world to live a materially rich life, the complex and brutal phase-out operation mechanism of humanity can only allow a few countries to have the power to produce goods. If China does not take the initiative to industrialize, the re-industrialization of the United States will not be easily realized. The right to produce human goods is a zero-sum game. Economists and sociologists cannot solve this problem at present. China is only experiencing a temporary economic downturn and shows "relative surplus." China's per capita steel production just reached the level of the developed countries, and per capita steel ownership is far below the level of the developed countries. Can the Chinese deserve to be called "the world's food"? Should they consciously lower the West in other respects? The industrial production capacity of a country requires the accumulation of several generations; the deindustrialization of a country. It only takes three to five years and it will be difficult to recover after it is lost. Russia is a good example. The Chinese should cherish their own industrial production capacity! Blindly arrogant, can not really solve the problem. The "program" refers to the five major indictments of industrial coal-fired boilers. From the author's point of view, it belongs to itself, and only sees the backwardness of China's industry. It is a negative way to solve problems. Solving problems requires the development of vision, positive attitude and rapid action. The technical backwardness of the boilers and the low level of economic operation are quite a few products in the 1970s and 1980s. As there are still many yellow-labeled vehicles, the correct way to do this is to eliminate these yellow-labeled vehicles. The government can use financial subsidies to encourage companies to purchase more energy-efficient and more efficient coal-fired boilers instead of “not teaching and ignoring.†Because of the backwardness of a small number of combustion boilers, all medium and small boilers in all prefecture-level cities in the country must be ban. This also reflects the fact that the country’s R&D investment in coal-fired boilers is far from adequate. It is considered to be the world's largest industrial country, and it is still unable to produce a small-to-medium-sized energy-efficient coal-fired boiler. No one said that a small-displacement vehicle is inefficient. On what basis, can it be considered that the energy efficiency of a small-ton boiler with a capacity of 2 tons can never be turned into efficient? The state can completely certify a qualified boiler manufacturer and force the upgrading of industrial enterprises. Each area has a boiler inspection and supervision agency, they have a complete way to improve the boiler operation level. Poor fuel compatibility is really a big problem. China's coal has a relatively high sulphur content, resulting in relatively high sulphur dioxide emissions. China's coal companies can no longer be extensively developed. The author is not a professional or curious. All of our foods have additives and they are all treated and harmless to health. Why are our coal companies so lazy in the past, so long as they dig out coal and put it on a truck to make big profits? Why can't they handle it, add some chemical substances, and treat the coal block to make it more conducive to burning? Environmental protection? If coal-fired boilers are banned because there are problems with some coal, this is like food and medicine. There is a problem. The government does not supervise the manufacturers and blames consumers for buying these substandard products. Environmental protection facilities are not in place and policies and regulations are not perfect. "Proposal" is proposed before the implementation of the new "Environmental Protection Law", the new "Environmental Protection Law" has solved the problem of imperfect policies and regulations. For most SMEs, there is a need for improvement in coal-fired environmental protection facilities. This is also an area they are not familiar with. This requires more supervision, education and training by the government's environmental protection department. In addition to selling boilers, boiler manufacturers should also be responsible for the installation and use of dust removal and desulfurization equipment to ensure that they can meet discharge standards; boiler users must ensure that they purchase qualified coal and ensure the normal operation of environmental protection facilities. In general, the whip cannot be used only by boiler users. Blindly shutting down, fines, and punishment will not really solve the problem. It will only leave behind a bad grudge and a bad economy.
