【摘要】 针对安钢高炉喷吹用煤现状,通过对煤粉添加氧化镁混合喷吹进行了试验。在试验条件下,氧化镁的添加量对混和煤的流动性影响不大;当氧化镁和煤粉混喷时,对煤粉具有助燃作用,但当氧化镁的添加量超过5%时混和煤最高燃烧温度下降。更多还原

【Abstract】 Compound injection charged with magnesium oxide in coal powder was tested based on the current coal powder injection situation.The amount of magnesium oxide has little influence on fluidity of compound coal under the test condition.Magnesium oxide will help combustion when injecting coal powder with it,but if the amount of magnesium oxide exceeds 5%,the max combustion temperature of mixed coal will reduce.更多还原
