【摘要】 针对分解炉低温燃烧工况,采用高温热天平和煤悬浮燃烧试验台,进行混煤燃尽特性实验方法及混煤燃尽时间与不同掺混比例之间关系的研究。提出混煤燃尽评判指数和实验方法,结果表明:在静态燃烧试验中,在低挥发分煤中掺入少量烟煤,明显改善煤的燃尽性能;悬浮燃烧时,混煤中的各单煤在混煤燃烧过程中基本保持其自身的燃尽特性。更多还原

【Abstract】 In this thesis,the experiment methods of combustion,the relation between burnout time and different ratio of blended coals were studied in the thermobalance and the test furnace for coal suspension combustion, and the related regularities were discussed to lower temperature combustion of calciner in cement.The burnout index proposed in this experiment study can quantitatively reflect the burnout characteristics of blended coals.In the test of thermobalance,blending a little anthracite to bituminous could obviously improve burnout characteristics;in the test furnace for material suspension reaction,the various mixing coals would retain their own burnout characteristics.更多还原
