　　A few days ago, the Harbin Ecological Environment Bureau issued the "Implementation Plan for Harbin Coal-fired Boiler Renovation" (hereinafter referred to as the "Plan"). According to the "Plan", in the next three years, Harbin will phase out 702 coal-fired boilers and replace 197,300 tons of coal.

　　Coal-fired boilers are eliminated. Within three years, realize the “clearing” of coal-fired boilers of less than 35 steam tons in the urban built-up area (core area) and the built-up area of ​​the county (city) Chengguan town of 10 steam tons and below, and implement special emission limits for 35 (inclusive) to 65 steam tons , The implementation of "coal-to-gas" heating boilers is included in urban peak shaving. Eliminate 702 coal-fired boilers and replace 197,300 tons of coal.

　　Ultra-low modification of coal-fired boiler. In 2020, there will be 28 coal-fired power plants capable of transformation and 93 coal-fired boilers of 65 steam tons and above in urban built-up areas, all of which will achieve energy saving and ultra-low emissions. In 2021, 17 coal-fired boilers of Xinma Group will achieve energy saving and ultra-low emissions. In 2022, three unqualified Hartou Thermal Power Plants will be merged into the Huaer Heat Source Plant. In 2023, 20 units of Huaneng Heating Company will be relocated as a whole, merged into the proposed new democratic heat source plant and eliminated.

　　Determine the transformation method. The transformation of coal-fired boilers is undertaken in the form of banning shutdowns, merging into the central heating pipe network, or replacing them with clean heating. Units implementing “coal-to-gas” should simultaneously remove coal-fired boilers, and gas-fired boilers after replacement shall implement special emission limits for air pollutants. Value requirements.

　　In areas covered by the clean coal-fired central heating pipe network, according to the requirements of the boiler property unit, priority will be given to the central heating pipe network; in the areas that are not covered by the central heating pipe network, clean energy may be adopted according to the wishes of the boiler property unit Alternatives to renewable energy heating installations eliminate coal-fired boilers. The necessary emergency and peak-shaving heating boilers can be retained. (Reporter Ding Yan)
