洗煤泥煤矸石流化床混烧技术工业应用研究

.Research and Application of Coal Washery Tailings/Coal washery Rejects Co Fired Fluidized Bed Combustion Technology

在分析了洗煤泥、煤矸石流化床混烧过程的基础上，介绍了浙江大学研究开发的洗煤泥、煤矸石流化床混烧技术的主要特点和试验研究结果。该技术的特点可概括为：洗煤泥结团燃烧，异重流化床，洗煤泥大粒度给料，分级配风燃烧减低氮氧化物排放，高效脱硫。并结合工程实际介绍了洗煤泥、煤矸石流化床混烧技术的应用。

Abstract The coal washery tailings/coal washery rejects co fired fluidized bed combustion technology is introduced.The developed technology are featured as:agglomerating combustion of coal washery tailings to decrease the elutration un burnt loss,dense bed material to ensure stable operation,two stage combustion to reduce the NOx emission,and mixing sorbent into coal washery tailing to improve the sorbent utilization etc.The operation results of commercial coal washery tailings/coal washery rejects co fired fluidized bed boiler are also reported
