基于环境保护与燃烧品质双重考虑的煤炭分类研究

Coal classification based on environmental protection and burning quality

以煤粉颗粒粒径分布为切入点,将环境保护与燃烧品质的双重考虑引入煤炭分类中,在试验设计与研究的基础上,依据污染潜势、燃烧性能和自吸附能力,通过聚类分析,将煤炭划分为4种类型:58%的样品为较理想的环保优质燃料;21%的样品燃烧性能较好,但环保性能有待提高;12%的样品环保状况较好,但燃烧性能有待提高;另有9%的煤炭样品环保性能和燃烧性能均相对不理想.

Both the environmental protection and the combustion quality were considered in the classification of coals based on the coal particle size distribution.According to the experimental design and research,the coal was divided into 4 types,through cluster analysis with the potential pollution,the combustion performance and self-adsorption capacity of the coals.The results show that,58% of the samples are type Ⅰ coal with better quality of environmental protection and combustion;21% of the samples are type Ⅱ coal with better combustion properties, but bad environmental performance; 12% of the samples are type Ⅲ coal with better environmental performance, but bad combustion properties ; and the other 9% of the samples are type Ⅳ coal, of which environmental performance and combustion properties are relatively unsatisfactory.
