为此，探讨了煤粉预热喷吹对混合煤粉爆炸性的影响，以期为强化喷煤燃烧提供一种新的有效工艺方法。
The effect of the preheated mixed pulverized coal on its explosiveness is discussed, and the aim is to provide a new effective technique for reinforcement combustion of the pulverized coal.
控制制粉和喷吹系统中的含氧量在15％以下，可以防止煤粉爆炸，降低气氛中含氧量可以采用充惰性气体的办法。
Keeping the oxygen content of the injection gas below 15%, possibly by introducing some N_2 into the gas medium, will prevent coal explosion.
为了避免锅炉爆炸事件的发生，炉内煤粉必须充分燃烧。
To prevent the explosive event of boilers, coal powder must be completely burnt.
若以空气为载体运送粉状物质(如煤粉、金属矿粉、面粉)，容易导致爆炸。
If air is used as a carrier for transporting the powdered substances (such as the coal dust, the metal mineral powder and the flour), explosions are easy to cause.
