The 13th Sulfur Dioxide, Nitrogen Oxide, Mercury and Fine Particle Pollution Control Technology & Management International Exchange Conference（第十三届二氧化硫氮氧化物、汞、细颗粒物污染控制技术与管理国际交流会）
第十三届 二氧化硫氮氧化物 汞 细颗粒物 污染控制技术
2009/4/3
我国以煤为主的能源结构是影响我国大气环境质量的主要因素之一，90%二氧化硫、67%氮氧化物、35%可吸入颗粒物、70%烟尘排放量来自于煤炭的燃烧，其中，燃煤电站、燃煤工业锅炉、燃煤炉窑等烟气排放污染问题最为突出，燃煤烟气污染控制是控制大气环境污染的重要途径，烟气脱硫脱氮脱汞除尘脱除超细颗粒物是控制燃煤烟气污染的重点。围绕我国大气污染控制方面的重大需求和国际技术前沿，通过关键技术研发和系统集成，开发...
