摘要
在500 kg/d危险废弃物等离子体熔融系统试验台上研究了熔融炉水冷炉壁的可行性、换热及挂渣特性,并在35 t/d的工业化装置上进行了应用.结果表明:随着水冷炉壁水量的增加,换热量增加,挂渣厚度增加;随着炉内总输入热量的增加,换热量也增加,但挂渣厚度减薄,挂渣厚度19～30 mm,单位面积水冷炉壁换热量20～30 kW/m2;水冷炉壁炉体的物料处置成本相比常规耐材炉壁略有增加,增加量为75元/t,增加幅度为3.75%.
Abstract
The feasibility,heat transfer,and slag hanging characteristics of the water-cooled furnace wall of the melting furnace were studied on a 500 kg/d hazardous waste plasma melting system test bench,and it was applied on a 35 t/d industrial device.The results indicate that with the increase of water volume in the water-cooled furnace wall,the heat transfer increases and the thickness of slag hanging increases.As the total input heat in the furnace increases,the heat transfer also increases,but the thickness of slag hanging decreases.The thickness of slag hanging is 19-30 mm,and the heat transfer per unit area of water-cooled furnace wall is 20-30 kW/m2.The material disposal cost of the water-cooled furnace wall body has slightly increased compared to conventional refractory furnace walls,with an increase of 75 yuan/t and an increase of 3.75%.
