　　A letter to the vast coal-fired heating units in Shenyang

　　Coal-fired heating units in Shenyang City:

　　In recent years, under the strong leadership of the municipal party committee and the municipal government, the majority of coal-fired heating units in our city have taken practical actions to shoulder the environmental protection responsibilities of the company in the practice of controlling coal pollution, overcoming difficulties, taking into account the overall situation, and building efficient pollution control facilities , And since November 1, 2019, the special emission limits for air pollutants from coal-fired boilers have been fully implemented, laying a solid foundation for the improvement of the city’s ambient air quality. However, we are still facing a severe situation. The overall environmental air quality of our city is still very fragile, and the smog management still has a long way to go. The winter heating period from 2020 to 2021 is coming soon. Coal-fired boilers for heating in our city will soon be put into operation. The majority of coal-fired heating units must continue to do a good job in the management of coal-fired pollution and continue to play the role of the main force in reducing coal-fired pollution.

　　The first is to do a good job in the maintenance of supporting dust removal, desulfurization, denitration and other pollution treatment facilities before the coal-fired boiler is put into operation, and reserve desulfurization and denitrification agents according to process requirements to ensure that the pollution treatment facilities can operate stably, and resolutely eliminate waste during the formal operation. Excessive emission of flue gas caused by the commissioning of pollution control facilities; the second is to control the quality of coal, and the ash and sulfur content of the purchased coal must meet the relevant regulations of the "Implementation Rules of the Interim Measures for the Quality Management of Commercial Coal in Liaoning Province" ; The third is to scientifically adjust the boiler load, make a reasonable plan for the use of coal-fired boilers, and avoid frequent start and stop of coal-fired boilers during the period from 22:00 at night to 7:00 of the next day when the atmosphere is unfavorable; The sealing control work of the facility ensures that the boiler body door is intact, the flue, valve, etc. are well sealed, and the system leaks; the fifth is to do a good job in the closed storage of dust-prone materials such as coal piles and slag (ash) piles. During coal loading and unloading, effective measures should be taken to reduce dust pollution; sixth, staff training should be done, and the skills of operators should be continuously improved to ensure that the operation status of environmental protection treatment equipment can be adjusted in a timely and reasonable manner to meet the “one plant, one policy” when heavy pollution occurs. "Regulations.

　　All coal-fired heating units are requested to scientifically operate and manage coal-fired boilers for the environmental air quality of Shenyang and for the air we breathe together. While ensuring the warmth of the residents in winter, prevent illegal activities and ensure that air pollutants meet the emission standards. Contribute to the winter air quality guarantee in Shenyang. For those who violate the relevant provisions of the Air Pollution Prevention and Control Law of the People’s Republic of China, exceed the emission standards of air pollutants, use coal that does not meet the quality standards, unclosed coal, coal slag, coal ash and other dust-prone materials or fail to adopt Effective coverage measures prevent and control the illegal activities of dust pollution, and the ecological environment department will strictly investigate and deal with it in accordance with the law.
