Research and Engineering Practice on Problem of Wax Coking in Rotary Kiln Incineration Slag
The coking situation of slag and wax incineration in a certain group's rotary kiln was re-searched under different working conditions.Combined with small-scale experiments of slag and wax incin-eration in muffle furnace,the coking influencing factors such as rotary kiln temperature,oxygen content,and material filling rate were identified.It was found that oxygen content below 3% was the direct cause of coking in the slag and wax incineration process,and the temperature of the rotary kiln and material filling rate were the key influencing factors of coking in the slag and wax incineration process.Based on this,the engineering verification was carried out,and process parameter control and operational suggestions were proposed to reduce or avoid the incineration of slag and wax in rotary kilns.
