本文研究预热对潞安喷吹煤粉的爆炸性能的影响。采用煤粉爆炸性测定仪，进行不同预热温度的潞安高炉喷吹煤粉的爆炸性能测定实验。结果表明：潞安高炉喷吹煤粉经预热后，煤粉的爆炸性基本没有变化。%This paper studied the effect of preheating on the explosion property of pulverized coal injection. The explosion property of pulverized coal injection with different preheating temperatures was tested by explosion property cryoscope. The results showed that explosion property not changed after preheating.
