| 中文摘要 |
| 研究以自行建立的固定燃烧源烟气颗粒物与水溶性离子监测采样系统和FPS4000与ELPI+结合使用的颗粒物分级采样系统,应用于北京市典型燃烧源烟气颗粒物排放监测.结果表明,北京市燃烧源烟气中总颗粒物基准排放质量浓度最高达83.68 mg·m-3,最低0.12 mg·m-3,颗粒物粒数浓度在104~106个·cm-3数量级上.北京市燃烧源颗粒物质量和数量浓度排放水平排序依次为:供暖燃气锅炉<电厂燃煤锅炉<供暖燃煤锅炉.PM10排放呈双峰或三峰分布,峰值均在1μm以下.从粒数分析,PM10中99.8%以上为PM2.5,并以PM0.1为主,占PM2.5的83%以上,但从质量上分析PM10中PM2.5与PM0.1的比例大幅降低,PM2.5占PM10的82%左右,PM0.1占PM2.5的27%~33%. |
| 英文摘要 |
| A self-built monitoring sampling system on particulate matters and water soluble ions emitted from stationary combustion sources and a size separated sampling system on particulate matters based on FPS4000 and ELPI+ were applied to test particulate matters in fumes of typical stationary combustion sources in Beijing. The results showed that the maximum concentration of total particulate matters in fumes of stationary combustion sources in Beijing was 83.68 mg·m-3 in standard smoke oxygen content and the minimum was 0.12 mg·m-3. And particle number concentration was in the 104-106 cm-3 number of grade. Both mass and number concentration ranking order of particulate matters emitted from stationary combustion sources in Beijing was: heating gas fired boilers2.5 accounted for over 99.8% of that for PM10, and that for PM0.1 accounted for over 83% of that for PM2.5. But the proportions of PM0.1 and PM2.5 in PM10 were significantly lower in quality analysis,the proportion of PM2.5 in PM10 was about 82%,and that of PM0.1 in PM2.5 was about 27%-33%. |
