燃煤工业锅炉大气污染物控制方案研究

摘要

基于中国燃煤工业锅炉大气污染物排放及治理现状,并结合国家相关产业政策和国内外技术发展趋势,以2008年为基准年,分析测算了2015、2020年燃煤工业锅炉大气污染物排放量,提出了适合中国国情的燃煤工业锅炉大气污染物控制技术路线.依据研究的控制方案,2015年,烟尘、二氧化硫及氮氧化物排放量分别为507万、458万、230万t；2020年,烟尘、二氧化硫及氮氧化物排放量分别为491万、423万、269万t.与2008年相比,大气污染物排放量变化不大,基本上做到了增容不增污.在此基础上,提出了燃煤工业锅炉大气污染物防治建议.%According to the situation of emission and control of air pollutants from coal-fired industrial boilers in China,combined with the national industrial policy and technology development trends at home and abroad,air pollutants emissions from coal-fired industrial boilers in 2015 and 2020 (target year) were forecasted based on the data in 2008 (base year).In addition,the air pollutants control route suitable for China was proposed.According to the control program,the emission of soot particle,SO2 and NOx are separately 5.07 million,4.58 million,2.30 million tons in 2015,and 4.91 million,4.23 million,2.69 million tons in 2020.Compared to base year,the air pollutants emission in target year does not change a lot which means the boiler capacity is increased without increasing pollutions emission.Based on the study,suggestions on prevention and control of air pollutants from coal-fired industrial boilers are proposed.
