Experts Comment On New Atmospheric Emission Standards

After implementation of the new standard, particulate matter will be reduced by 660 thousand tons and sulfur dioxide will be reduced by 3 million 140 thousand tons. There are many industrial boilers in China, which are mainly distributed in densely populated residential areas and industrial areas, which have great influence on the local ambient air quality.

The newly revised standard for the discharge of air pollutants from boilers has increased the emission limits of NOx and Hg and their compounds in coal-fired boilers, specified the special discharge limits of atmospheric pollutants, cancelled the requirements for implementing different emission limits according to functional areas and boiler capacity, and the limits of initial emission concentration of soot in coal-fired boilers, and raised the requirements for pollutant discharge control.

The implementation of new emission standards for boilers will bring good environmental benefits. Wang Jian, deputy director of the Department of pollution prevention and control of the Ministry of environmental protection

In the new emission standard Mercury has been put into the standard for the first time, and has higher requirements for traditional particulate matter and sulphur dioxide emissions. Taking Luoyang as an example, the total number of boilers in Luoyang is 2219.

If the new pollution discharge standards are implemented in the city's boilers, large unregulated boilers will be carried out. Upgrading Emission pollution will be reduced by at least 50%. Jiang Weidong, chief engineer of Luoyang boiler and Pressure Vessel Inspection Institute

Due to the large industrial park The dust removal, desulphurization and denitration units are quite advanced. On the contrary, these small boilers with large quantities and wide quantities are not only unclear in number, but also differ greatly in the number of actual boilers and the actual number of boilers. There is also a lack of dust removal, desulphurization and denitrification devices. This leads to the emission of sulphur dioxide and dust from the boiler is generally not up to standard.

According to the latest standard management transformation plan, the implementation of the new standard will directly lead to environmental investment of 370 billion yuan ~4500 billion yuan, and the annual operation cost of environmental protection facilities will cost about 3 billion 350 million yuan ~47.5 billion yuan.

Governance transformation will drive 100 billion yuan investment, and the state will also increase financial support for the comprehensive improvement of local coal-fired boilers. Guo Fanli, consultant director of CIC Consulting Ltd.
