Dalian governs coal-fired boilers to help green development.

  Introduction: Many northern cities have encountered great difficulties in the urban environmental management due to the large-scale use of coal-fired boilers, especially for the three northeastern provinces, whether they are industrial coal-fired boilers or coal-fired heating boilers, and are widely used . But nowadays, Dalian is much concerned about its achievements in green development because Dalian is expected to rank 15th among the 74 major cities in China in 2017, ranking the first in northern cities for the first time.

 

 Many northern cities have encountered great problems in the urban environmental management due to the large-scale use of coal-fired boilers. Especially for the three northeastern provinces, they are widely used both for industrial coal-fired boilers and coal-fired heating boilers. But nowadays, Dalian is much concerned about its achievements in green development because Dalian is expected to rank 15th among the 74 major cities in China in 2017, ranking the first in northern cities for the first time. This is the "Four Control and One Transfer" project focused on controlling coal-fired pollution, controlling motor vehicle pollution, controlling dust pollution, controlling motor vehicle pollution and adjusting industrial structure in Dalian City, so that the quality of the atmospheric environment is significantly improved.

  Among them, the comprehensive improvement of coal-fired boilers starting in 2016 contributed the most to the improvement of ambient air quality in Dalian. Dalian Municipal Party Committee and government formed by the party and government jointly environmental supervision regularly and strongly promote. In the case of tight fiscal funds, come up with more than 7 billion for comprehensive treatment of coal-fired boilers.

  Before the remediation, Dalian City, delineated a notice of non-combustible zone; find out the bottom of coal-fired boilers, carried out a comprehensive monitoring and monitoring; well in advance of the funding needs and policy reserves. In the remediation, Dalian, on the one hand, has a complete range of remediation and covers the entire downtown area of the city and urges the implementation of the simultaneous implementation of the counties, districts and troops. On the other hand, remediation is complete. While banning coal-fired boilers of 10 tons and below, it is required to retain a comprehensive upgrade of coal- Renovation, and all installed on-line monitoring, networking with the environmental protection department. At the same time, rectification work information throughout the open, all coal-fired boiler remediation list released to the community, all exceeded the list of coal-fired boiler business released to the community, every two months to the community release of the regional progress and rankings.

  Combined with the clean and heat work in the north, Dalian also strongly promotes clean energy boilers. Since 2016, a total of 700 coal-fired boilers have been transformed into clean energy boilers. Under the premise of no additional boilers, the heat source of electric power enterprises has been tapping into the potential and about 10 million new heating capacity has been added. Since 2016, Dalian has banned more than 1,500 coal-fired boilers and upgraded more than 1,400 units. The city's coal-fired boilers comprehensive remediation work to reduce the total amount of about 200,000 tons of coal consumption, after the remediation Dalian heating season compared to the same period before remediation of ambient air sulfur dioxide decreased by about 38.8%, PM10 decreased by about 17.8%.
