煤炭燃烧过程中污染物排放特性研究

Research on Pollutant Emission Characteristics during Coal Combustion Process

为进一步探究煤炭燃烧过程中的污染物排放特性,本次研究针对低热值煤材料展开重点研究,通过燃烧实验,首先确定了中煤、煤矸石和煤泥三种煤炭材料在燃烧过程中的一氧化氮和二氧化硫排放特性,在此基础上,进一步探究了煤炭材料掺混模式下的污染物排放特性。结果显示,掺混模式下的污染物排放情况较单一煤种有所改善,因此这种模式在理论上更具应用可行性。

In order to further explore the emission characteristics of pollutants in the process of coal combustion,this study focused on the low calorific value coal materials.Through combustion experiments,the emission characteristics of nitric oxide and sulfur dioxide in the combustion process of three coal materials,middling coal,gangue and slime,were first determined.On this basis,the emission characteristics of pollutants in the mixing mode of coal materials were further explored.The results show that the pollutant emissions under the blending mode have improved compared to a single coal type,making this mode more theoretically feasible for application.
