求翻译：另外，燃煤粉尘有三氧化二铁成分，可以催化另一种来自燃煤的污染物，二氧化硫氧化生成三氧化硫，进而与吸附在粉尘表面的水化合生成硫酸雾滴。是什么意思？

In addition, the coal dust with ferric oxide components, can catalyze other pollutants from coal, sulfur dioxide oxidation of sulfur trioxide, then dust with adsorbed on the surface of the water combine to form sulfuric acid droplets.

In addition, the coal dust is 3 oxidation catalyst 2 iron components, can be another kind of pollutants from coal burning sulfur dioxide, sulfur dioxide generated 2 3 sulfur dioxide, and by extension to the water surface adsorption in dust generated 500-600sulfuric acid fog drop.

In addition, coal dust iron oxide compositions, catalyze other pollutants from coal-fired, sulphur dioxide oxidation of sulfur trioxide, and adsorption on the surface of dust and water combination generates sulfuric acid droplets.

In addition, the coal-fired dust is three and oxidize two iron compositions, can catalyze another kind of pollutant from fire coal, sulfur dioxide oxidize turn into three oxidize sulphur, absorb in dust ink compound of surface producing sulfuric acid droplet.
