燃煤电厂蓝烟现象的成因、数学模型判定及解决方法

The Causes Countermeasures and Relative Mathematical-model Judgment of Blue Smoke in Power Plant

通过对燃煤电厂蓝烟的成因进行分析,得出SO3经湿法脱硫形成H2SO4气溶胶是产生蓝烟的直接原因。推导出了燃煤硫分与SO3排放浓度的数学模型,提出了解决蓝烟问题的方法,为采用类似烟气处理工艺电厂提供参考。

This article developed a deeply survey on the cause of blue smoke formation in the power plant. It is concluded that the H2 SO4 aerosols formed during wet FGD（flue gas desulfurization）of SO3 is the direct reason for the blue smoke formation. On the basic of the analysis, the mathematic model for the relation between sulfur content of coal and emission concentration of SO3 is derived and relative countermeasures are proposed. The work of this paper may offer some references for the similar gas treatment of power plant.
