摘要:

窑膛A出料轻烧白云石的CO2量波动较大,发现18号和20号枪对应的喷枪隔热盖板温度超高150℃以上,该盖板对应的喷枪已经烧坏,喷枪护罩烧坏的可能性非常大。为了确定烧坏程度,停窑打开喷枪盖板进行检查,发现2#和3#喷枪烧断,对应的护罩严重烧坏,针对此问题进行研究并给出了比较安全可靠的解决方法。

Abstract:

The CO2 of soft burnt dolomite discharged from A shaft of the kiln varies greatly. Polling inspector has found that the temperatures of the thermal insulation covering plates of No.18 and No.20 lances exceed 150℃. After analysis, the lances at the covering boards are burnt out and there is very high possibility that protection covers of lances are burnt out too. In order to determine the damage degree of the lances the operation of the kiln is stopped to carry out inspection of covering plates and it is found that No.2 and No.3 lances are broken by burning and the corresponding protection covers are burnt out. Aiming at the problems the safer and more reliable solutions are provided.
