【摘要】 高炉喷吹氧煤粉流组合分布[O]/[C]是决定煤粉燃烧的重要条件,它直接反映了氧煤的混合状态,与喷煤强度、富氧率、O/C原子比等相关。各种氧煤枪比鼓风富氧有较高的[O]/[C]值,凹枪和中心走氧枪具有较好的强化煤粉燃烧的特性。更多还原

【Abstract】 The combined distribution of oxygen-coal [O] / [C] injected into blast furnace is an important factor influencing on pulverized coal combustion. It shows directly the mixed property of oxygen-coal flow, and has a good relationship with intensity of injected coal, oxygen enrichment and O/C atom ratio. The [O]/[C] value of different types of oxygen-coal lance generally is better than that of oxygen enrichment in blast. The concave oxygen-coal lance and the lance with central oxygen flow both are better to intensify the coal combustion.更多还原
