1·Small particles of ash, for example, are normally removed by forcing the flue gases, as the fumes from the furnace are known in the trade, between electrically charged plates.
例如令烟道内的气体通过带有不同电荷的金属板从而去除一些灰尘颗粒，因为这些从熔炉散发出的浓密毒烟为业内所共知。
2·Said the flea, "Let us fly！" Said the fly, "Let us flee！" So they flew through a flaw in the flue.

4·Other pollutants, after all, are essentially impurities, which can be washed from the coal or filtered out of the flue gas.
毕竟那些可以从煤炭中或烟道气体中滤除的其他污染物质本身就是杂质。
5·The simplest, and easiest to bolt on to existing plants, treats carbon dioxide like any other pollutant, and extracts it from the flue gas.
同其它污染物一样对待二氧化碳并将其从烟道气体中分离出来是改造现有发电站的设计中最简单易行的方案。
