Effects of space heating on the pollutant emission

May 15, 2020 · The results for coal-fired boilers show that the pollutant emission concentration is generally higher for small coal-fired boilers below 20 t/h due to limitations of the desulfurization equipment . SO 2 emission per unit of flue gas from a small boiler can be 2 to 3 times larger than that in a large coal-fired boiler above 80 t/h, and soot emission can be 8 to 10 times larger.

Current and future emissions of primary pollutants from

Oct 01, 2017 · Estimated SO 2, NO x, PM 10, PM 2.5, EC, OC, CO and NMVOC emissions from coal-fired power plants in Shaanxi in 2012 were calculated ( Fig. 3 (a) ). The largest emission was NO x (314.9 kt), which was about twice of SO 2 (152.4 kt) due to province WDE of SO 2 (~ 81%) was over two times of that for NO x (~ 32%).

Environmental Impacts of the Revised Emission Standard for

According to the revised emission standard of air pollutants for boilers in Beijing, since April 1, 2017, the required NOx, SO2 and PM concentrations of new-founded boilers are ≤ 30 mg m –3, ≤ 10 mg m and ≤ 5 mg m–3, respectively; and those of in-use boilers are ≤ 80 mg m –3, ≤ 10 mg m and ≤ 5 mg m–3, respectively (BMEPB, 2015). To reduce the
