| 摘 要： | 为降低煤中砷元素对大气造成的污染,采用煤燃烧实验研究了煤燃烧过程中砷的析出规律。研究结果表明,在煤燃烧过程中,随着燃烧温度的升高,煤中砷的释放率逐渐增大,残留到燃煤灰渣中的砷含量逐渐减少。在不同的燃烧温度下,燃煤灰渣量几乎没有改变,煤中砷的释放率却有较大的差异。燃煤排放的飞灰和烟尘以及粉煤灰的裸露堆放是环境砷污染的主要途径之一。

| Abstract: | Aimed at reducing air pollution due ning arsenic release due to coal combustion by coal to arsenic in low coal, this paper studies the law gover- combustion experiment. The results show that coal corn- bustion process makes for the increased combustion temperature, setting off a gradual increase in the release rate of arsenic in coal and consequently a gradual decrease in the arsenic content in coal residue ash. At dif- ferent combustion temperature, there is virtually no change in coal ash quantity, but there is a great difference in the release rate of arsenic in coal. Fly ash and smoke dust caused by coal combustion, and dust caused by coal ash and slag pile are one of the main factors for arsenic contamination of ecological environment. |
