摘要
介绍湿法脱硫后烟气的特点和火电厂常见烟囱结构形式及其特点,比较烟气脱硫(FGD)系统设置与不设置烟气加热系统的优劣,从技术和经济两方面分析论证了排烟筒的材质选择及防腐处理措施,经比较推荐采用国产泡沫玻化砖钢套筒式烟囱。
Based on the characteristics of flue gas after wet FGD, the advantages and disadvantages of FGD and non- GGH are compared. The structure style of common chimney and their characters are presented. With the economic comparison,the chimney of steel inner shell with domestic vitrified brick should be recommended.
