To further promote the comprehensive management of coal-fired dzl 4 boiler of zgs, Jincheng City, Shanxi Province, according to "Jincheng Blue win the Battle of three-year action plan" requirements, plans to complete 109 units of 10-20 tons of steam "small coal-fired boilers" within this year the phase-out, at the same time, Jincheng will start working out of 35 tons of steam coal-fired boilers.
This year, Jincheng counties (cities, districts) the environmental sector will urge the relevant enterprises and institutions to eliminate the basis of 10 tons of steam and coal-fired boilers on in 2018 to accelerate the phase-out and 20 tons of steam coal-fired boilers. This year, the city to complete 109 units (10-20 tons of steam boilers) working out of a total of 589.5 tons of steam boilers; at the same time, Jincheng will also speed up the foundation and 20 tons of steam coal-fired boiler out, start 35 tons of steam phase out coal-fired boilers, in principle, within the city's new domain-wide 35 tons of steam coal-fired boilers.
In addition, Jincheng will accelerate the transformation of ultra-low emission. Before the end of September this year, the city will complete 52 units (65 tons of steam per hour and higher coal-fired boilers) coal-fired heating boilers ultra-low total of 4530 tons of steam boilers transformation, and the county (city) built-up area, biomass boilers emissions transformation. After transformation, under condition of the reference oxygen content of 6%, soot, sulfur dioxide, nitrogen oxides emission concentration of these boilers respectively not higher than 10 mg / m, 35 mg / m and 50 mg / m.
Transformation of low nitrogen in the combustion aspect, before the end of October, Jincheng station 610 will complete the transformation of low-nitrogen combustion Total 1940.15 tons of steam gas boiler, after completion of the transformation, the boiler NOx emission will not exceed 50 mg / m.
