摘　　要：在空气和氧气的不同条件下，研究并对比了不同品种废塑料颗粒与煤粉的燃烧特性。废塑料在1250℃条件下经尾气测试分析表明：气化燃烧快速反应时间明显早于煤粉；4种废塑料的燃烧率平均高于煤粉20～25个百分点，在同样条件下其燃烧时间快于煤粉10～15s；在富氧条件下废塑料和煤粉的燃烧率和燃烧时间都有不同程度的提高。In this article, the combustion characteristics of waste plastics particles in various kinds comparing to the fine coal are studied under the different blast and oxygen enrichment conditions. As the results shown, the reaction time of gasification and combustion of waste plastics is earlier than that of fine coal in analysis of exhausting gas at 1 250℃. Under the same condition, the average combustion rate of four waste plastics is 20% - 25% higher than that of the fine coal; while the combustion time is shorten for 10 - 15 s. And at the condition of oxygen-enriched blast,the combustion rate and reaction time of waste plastics and fine coal both are increased to a certain extent.
