Recently, in Hebei (Shijiazhuang, Tangshan, Handan, Xingtai, Baoding, Cangzhou, Langfang, Hengshui, Taiyuan), Shanxi (Yangquan, Changzhi, Jincheng), Shandong (Jinan, Zibo, Jining, Texas, Liaocheng, Binzhou, Heze ), Henan Province (Zhengzhou, Kaifeng, Anyang, Hebi, Xinxiang, Jiaozuo, Puyang) and other municipal people's government, security male New District management Committee, Dingzhou, Xinji, Jiyuan City people's government and the China National petroleum Group Co., Ltd., China petroleum and Chemical Group Corporation, China national Offshore oil Group Co., Ltd., State grid Co., Ltd., China Railway jointly issued on the issuance - notice "2018 in Beijing, Tianjin and the surrounding areas in 2019 autumn and winter tackling air pollution comprehensive management action plan" of.
The following are the provisions on the rectification of energy.
Setting goals: adhere to the principle of maintaining stability in the consolidation of ambient air quality improvement achievements, promote air quality continues to improve. Fully completed to improve air quality objectives 2018; Oct. 1, 2018 to March 31, 2019, (of PM2.5) Jingjinji average concentration of fine particles and the surrounding area fell about 3%, and more severe pollution days year reduced by about 3%. The main embodiment of the above-mentioned range is "26 + 2" city.
Execution method: to promote clean heating, iron revolution, transformation of provincial enterprises mentioned standard, focusing on the consolidation of comprehensive "scattered pollution" enterprise rectification results, pay close attention to diesel trains, industrial furnaces and volatile organic compounds (VOSc) special rectification, strengthening regional joint prevention and control, to effectively deal with heavy pollution weather, strict supervision and accountability, to further promote the comprehensive management of air pollution in autumn and winter tackling behavior.
First, strictly control the "two high" industry capacity. Before the end of December 2018 to complete the delineation of ecological protection red line. At the same time, increase the iron and steel, coking, building materials industry production capacity out and Yajian efforts to be included in the capacity of iron and steel enterprises, supporting the need to also sign sintering, coke oven, blast furnace and other equipment. 2018, steel production in Hebei Yajian can withdraw 10 million tons, 2.25 million tons in Shanxi Yajian quit, Shandong Province Yajian raised 3.55 million tons. Ensuring electricity, heat stable supply basis, 38 out of the task a total of 2.77 million kilowatts of coal-fired units of small thermal power units in the region.
Second, to deepen industrial pollution control. Since October 2018 1 May, the strict implementation of thermal power, steel, petrochemical, nonferrous metals (excluding aluminum), cement industry, industrial boilers and air pollutant emission limits in particular, to promote pollution control facilities upgrading in key industries. Continue to promote the industrial enterprises fugitive emissions control, under the conditions of safe production license, the implementation of closed storage, custody transfer, collection system, the end of December 2018 basically completed.
Third, effectively promote clean heating. The pooling of resources and vigorously promote the coal for governance, the country should be in accordance with the pre-heating period in 2020 basically completed the life and motivations of heating coal for alternative tasks required plains, to develop a three-year implementation program to determine the annual task of governance, both agricultural greenhouses, animal building, etc. bulk coal governance, promote energy-saving buildings synchronization, improve energy efficiency.
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.
Fifth, speed up clean energy alternatives. Of coal, petroleum coke, residual oil, heavy oil as the fuel of a heating furnace, heat treatment furnace, a drying furnace (kiln), and accelerate the use of clean energy and the use of plant waste heat, thermal power plants and the like instead.
Before the end of December 2018, the basic ban coal-fired stove, the iron and steel industry, coal-fired heating boilers; nonferrous metals industry basically out of coal-fired kilns, coal-fired reverberatory furnace, lead melting pots and pans electrical lead with coal as a fuel; basically eliminated coal-fired cogeneration heating the heating pipe network coverage, drying furnace (kiln); blast furnace gas, coke oven gas desulfurization transformation embodiment, the gas hydrogen sulfide concentration of less than 20 mg / m; diameter vigorously eliminate hearth 3 meters fuels gas furnace; industrial park focused on the use of gas stoves, they will not have to switch to natural conditions, should build a unified clean coal gas central principle. Prohibition blended sulfur petroleum coke.
