煤粉燃烧污染物排放特性的试验研究

Experimental Study on Pollutant Emission Characteristics During Combustion of Pulverized Coal

由煤燃烧产生的NOx、SOx引起的污染受到世界各国的重视,降低污染物排放成为燃烧研究的重要课题。选择了某电厂常用的4种褐煤和3种烟煤,研究了单煤及其混煤的污染物排放特性。结果表明:氧浓度增加时,或煤粉较细时,NOx的排放增加;而水分能降低NOx的排放;SOx的排放规律不明显。

Pollution due to NO, and SOx, brought about by the combustion of coal, has attracted the attention of countries all over the world and, how to reduce emission of pollutants, has become a vital topic in the field of combustion research. For the benefit of promoting clean combustion in large capacity power plants, four kinds of lignite and three kinds of bituminous coal, as generally fired by a certain power plant, were chosen, to be used singly or blended, for their pollutant emission characteristics.
