用生料易烧性指数控制回转窑煅烧温度

研究了带余热发电回转窑窑灰对熟料煅烧的影响,结果表明,窑灰的掺入对生料的易烧性和回转窑的煅烧有很大的影响,其中存在一个最佳掺入量。应该严格控制窑灰的加入量,才能保证窑的优质高产。生料的煅烧温度与其易烧性有直接的关系,在设备条件一定的情况下,可以用易烧性来控制窑的煅烧温度。

Using burnability index to control the burning temperature of rotary kiln

Influences of rotary kiln dust on clinker burning are investigated in this paper,which is a sub-project of Tangshan mechatronics project-cement synthetical intelligent automatic system.The results show that adding of rotary kiln dust affects both burnabiliy of raw mix and burning of rotary kiln strongly and a best adding amount exists.Adding amount of kiln dust must be controlled strictly to keep the kiln operating well.The burning temperature of raw mix has direct relations with its burnatiliy.Under the same device conditions,using burnability index can control burning temperature of the kiln.
