燃煤烟气SO_3检测及控制技术探讨

Discussion on SO_3 Detection and Control Technology in Flue Gas

燃煤电厂烟气中SO3含量约为SO2含量的0.8%~3.5%,检测难度大,对人体危害极大。随着环保标准日益严格,电厂对SO3的管控应提上日程。文中研究了燃煤电厂烟气中SO3的生成途径,对SO3检测技术进行探讨,提出了SO3的控制方法。

The content of SO3 in coal- fired power plant flue gas is about 0. 8% ~ 3. 5% of SO2 content,SO3is very harmful and there are a lot of difficulties to detect. With increasingly stringent environmental standards,management and control of SO3 should be put on the agenda. By analyzing the formation of SO3 in the coal- fired power plant flue gas,SO3 detection techniques are discussed,SO3 control methods are proposed.
