浅谈危险废物焚烧回转窑窑皮的建立
|
摘要
窑皮对延长危险废物焚烧回转窑耐火砖寿命有非常关键的作用,耐火砖所占的比例特别大,如果掉窑砖造成停窑,火砖的费用不算,产量的损失更大。文章通过对挂窑皮所需物料化学成分、烧成温度和火焰控制、喂料量和窑速等因素进行研究,并对生料熔渣进行分析,探索出最佳窑皮建立工艺。
Adhering coating is very critical to extend the service time of refractory bricks of rotary kiln. When some refractory bricks dropped, the loss of production is huge except the price of refractory bricks. In the paper the optimum technology of adhering coating were obtained by studying chemical component of material used to adhering coating, firing temperature of coating, flame control, feeding quantity and speed of rotary kiln. In addition, raw material and slag were analyzed.
