摘要
以玻璃钢和造纸废料为试验原料,利用自主开发的成套装备进行热解焚烧试验研究,考察了造纸废料单独热解及其与玻璃钢共热解时二燃室内的温度变化情况。结果表明:1.25 t造纸废料单独热解时二燃室的温度不高并且波动较大,二燃室在650℃以上共维持约5 h。掺入0.4 t玻璃钢后,总计1.25 t的玻璃钢和造纸废料混合物可使二燃室温度在850℃以上维持6 h,并且最高温度达到了972℃,说明玻璃钢的掺入对于二燃室温度的提高非常有利。但是,与造纸废料95%以上的减重率相比,玻璃钢中由于含有大量的玻璃纤维和碳化硅等无机物,试验中玻璃钢与造纸废料的减重率仅为73%左右,减量化并不明显。
Fiberglass and papermaking waste were used as test materials in the experiment study of pyrolytic incineration,which was carried out by using the complete set of equipment that was independently developed.The temperature variation conditions in the secondary combustion chamber during the separate pyrolysis of papermaking waste and its co-pyrolysis with fiberglass were investigated.The results showed that during the separate pyrolysis of 1.25 tons of papermaking waste,the temperature of the secondary combustion chamber was not high and fluctuated greatly,and the secondary combustion chamber could maintain for about 5 hours above 650℃.After adding 0.4 tons of fiberglass,a total of 1.25 tons of the mixture of fiberglass and papermaking waste could maintain the temperature of the secondary combustion chamber above 850℃for 6 hours,and the maximum temperature could reach to 972℃,which indicated that the addition of fiberglass was extremely beneficial for the improvement of the temperature of the secondary combustion chamber.However,compared with the weight reduction rate of more than 95%of papermaking waste,the weight reduction rate of the mixture of fiberglass and papermaking waste was not obvious,which was only about 73%due to the large amount of inorganic substances such as glass fiber,silicon carbide in the fiberglass.
