Detonation equipment market in thermal power industry will erupt

According to the World Health Organization's annual average concentration distribution of inhalable particulates in 1082 cities worldwide from 2008 to 2010, 32 provincial capital cities in China participated in the ranking, the best being Haikou City, ranked 814th, and the rest were after 890. Beijing is ranked 1035.

This year, smog pollution seems even more serious. The study found that large-scale coal-fired boilers, heating and heating fuel and coal-fired boilers, various industrial kilns and furnaces, and motor vehicle exhausts are the main sources of PM2.5.

To reduce pollution, starting from January 1, 2012, the thermal power industry implemented a national emission standard of 30 mg/m3 of soot. However, at the same time that the state repeatedly recalled the “contract” in the thermal power industry, petrochemical, chemical, non-ferrous, cement and other industries did not seem to be moving.

"In addition to continuing to promote pollution reduction in the power industry, we must also accelerate the process of desulfurization and denitrification in non-electric key industries such as steel and cement, and implement coal gas boiler flue gas treatment in accordance with local conditions." Air pollution in the power industry in 2013 organized by the China Environmental Protection Federation In the meeting on governance technology and experience, Wang Jian, deputy director of the Department of Pollution Prevention and Control of the Ministry of Environmental Protection, emphasized again.

How is the thermal power industry's "world's most stringent standard" landed?

“It is not wrong to focus on the emission reduction in the thermal power industry.” At the exchange meeting, Zhao Penggao, Deputy Director of the Department of Resource Conservation and Environmental Protection of the National Development and Reform Commission said. However, Zhao Penggao also pointed out that the "Emission Standard for Air Pollutants from Thermal Power Plants (GB13223-2011)", which was implemented on January 1, 2012, can be considered as one of the most stringent standards in the world. Zhao Penggao compared the standard with the standards of the European Union, Japan, Canada, Australia, and other countries, and considered it much stricter than the developed countries. For example, Japan's soot emission standard is 50-100 mg/m3, and China's new standard requires 30 mg/m3; Japan's sulfur dioxide and nitrogen oxide emission standards are 200 mg/m3, and China is 100 mg/m3.

However, to implement this “the most stringent standard in the world”, the thermal power industry must pay a huge economic price, and there are also difficulties in technical equipment and other aspects. Taking desulfurization as an example, the standard is from 400 mg/m3 to 30 mg/m3, which takes only 5 years or so, but the desulfurization equipment built according to the old standard is generally 15 years old, and companies need to implement new standards, or Allowing equipment that is still in service to retire in advance, or adding new additional equipment, is costly.

Zhao Penggao explained: “From an economic point of view, if the smoke and dust emissions reach 30 mg/m3, there will be an increase in the cost. The current estimate is that at least 2 cents per kilowatt hour will be added, but the power generation price of the power plant is set by the country, such as Electricity prices are not adjusted, and power generation companies are economically unsustainable. From the point of view of technical equipment, electrostatic discharge dust collectors will be added to the discharge standards. The problem is that there is no room for the power plants to install new dust removal equipment."

“We have seen some thermal power plants in Shanxi and Inner Mongolia that many of the 300,000 and 600,000 megawatt generator sets have dust emissions above 100 milligrams per cubic meter, or even hundreds of milligrams per cubic meter.” Chongqing Institute of Environmental Science Xiao Rongxu, vice chairman of the China Industry and Environmental Protection Industry Association, believes that at present, the key to the thermal power plant is the “landing” problem of the new emission standards.

Denitrification equipment will erupt this year

At present, atmospheric pollution prevention and control, especially in the area of ​​flue gas denitrification, has met the conditions for large-scale advancement. On the one hand, it has a relatively high level of technological maturity. Mainstream denitrification processes, including front-end low-nitrogen combustion, back-end SNCR and SCR technologies, have been Most enterprises have mastered; on the other hand, a series of policies, such as the “tightest in history” atmospheric emission standards and signing of emission reduction responsibilities with major companies, have been pushed down. This year, the prelude to denitrification in thermal power plants has been gradually opened, and the market structure has taken shape. The foundation of industrialization is already in place. Industry sources explained that currently, in terms of pollution control, electrostatic precipitators and baghouse dust removal can all achieve relatively high efficiency. However, the dust removal market is already relatively stable, and there will be no explosive growth, and there are still market opportunities in the desulfurization and denitrification market.

From the perspective of the development of the desulfurization industry, under the mandatory constraints of the total control standards, during the “11th Five-Year Plan” period, national desulfurization units have significantly increased before the comparison. According to CEC statistics, as of the end of 2011, the thermal capacity of coal-fired flue gas desulphurization units in China was 684 million kilowatts, and the cumulative operational capacity was 518 million kilowatts. The capacity of the national thermal power plants that have been put into operation for flue gas desulphurization units accounted for 75.73 of the national coal-fired unit capacity. %.

In 2013, the market for power denitrification reform broke out. Firstly, the power industry accounts for 48% of domestic nitrogen oxide emissions. Second, in July 2014, all existing thermal power units must meet the emission standards announced by the Ministry of Environmental Protection's “Emission Standards for Air Pollutants from Thermal Power Plants”. In the first half of 2012, as a result of its low profit, the thermal input to thermal power has been less than expected. As of the first half of 2012, the average denitrification rate was only 40%; last week, the National Development and Reform Commission issued the “Notice on Expanding the Scope of Pilot Pricing Policy for Denitrification Electricity Price”. The pilot scale of denitrification electricity prices was expanded from 14 provinces to the whole country, reducing the environmental protection expenditure pressure of power plants. In the long run, the decline in air pollutant emissions will depend on industrial upgrading (de-nitrification of industrial boilers, elimination of outdated production capacity, etc.) and all-round energy conservation (energy-saving reforms such as central heating, combined heat and power, and waste heat recovery).
