According to the country report, before the end of October 2018, "26 + 2" cities to complete the bulk coal substitution 3.62 million. Among them, Beijing replace 150,000, Plains basically bulk coal "cleared"; Tianjin replace 190,000, and strive to the end of October 2019, the basic completion of coal for alternative work; Hebei replace 1.74 million, and strive to 2019 basically completed before the end of October to the south of Beijing, bulk coal substitute work north of Shijiazhuang City; Shanxi replace 280 000, 450 000, Shandong Province, alternative, Henan replace 810,000. Around the township or county as a unit overall progress, complete replacement of bulk coal regions, and adopt comprehensive measures to prevent bulk coal burning complex.

Fourth, to carry out comprehensive improvement of the boiler. According to the law to increase the small coal-fired boilers in accordance with regulations (including tea furnace, operating a stove, grain storage and drying equipment, coal-fired facilities) elimination efforts.

Before the end of December 2018, Beijing, Tianjin, Hebei (city) basically eliminated 35 tons of steam per hour coal-fired boilers; Shanxi, Shandong, Henan eliminated 10 tons of steam per hour and coal-fired boilers, urban area basically eliminated 35 tons of steam per hour at coal-fired boilers.

Before the end of October 2018, Tianjin, Hebei, Shandong, Hebei (city) basically completed 65 tons of steam per hour and above ultra-low emission coal-fired boilers transformation, to achieve ultra-low-emission coal-fired power plant level. Biomass boilers should be dedicated boiler, coal and other prohibited blended with other fuels, efficient dust bags and other ancillary facilities. Actively promote the urban area of ​​biomass boilers ultra-low emissions transformation.

Accelerate the transformation of low nitrogen gas-fired boilers, in principle, after the transformation of Danyang outdoor emission concentration is not higher than 50 mg / cubic meter, before the end of October 2018, Beijing basically completed the task of transformation of low nitrogen gas boiler; Tianjin complete the transformation of 222 units, 5908 tons of steam; Hebei Province, completed 353 units, 8028 tons of steam; Shanxi Province, completed 17 sets of 100 tons of steam; Shandong Province, completed 182 units, 409 tons of steam; Henan Province, and strive to complete 278 units, 1450 tons of steam.
