摘要

以废旧冰箱聚氨酯泡沫（PUF）为原料,选取玉米秸秆（CS）、木屑（WS）、煤粉（PC）作为添加剂制备成型燃料,采用热重分析仪和氧弹量热仪研究3种添加剂对PUF成型燃料燃烧性能及热值的影响,并采用Coats-Redfern积分法研究其动力学行为。结果表明：3种添加剂会使固定碳燃烧阶段最大失重速率峰值温度向低温区移动,会降低PUF成型燃料的残渣剩余量与活化能、提高热值。此外,添加质量分数为8%的WS的PUF成型燃料残渣量低、综合燃烧特性指标高、燃烧充分、活化能较低,PUF成型燃料的燃烧效率最佳。

Abstract

Waste refrigerator polyurethane foam （PUF） was used as raw material to prepare molding fuel. Corn Stalk （CS）, Wood Sawdust （WS） and Pulverized Coal （PC） were selected as additives. The effects of three additives on PUF molding fuel combustion performance and calorific value were studied by thermogravimetric analysis and oxygen bomb calorimeter. The Coats-Redfern integral method was used to discuss its combustion kinetic. The results show that the three additives could shift the peak temperature of the maximum weight loss rate in the fixed carbon combustion stage to the low temperature zone, reduce the residual amount and activation energy, and increase the calorific value. The best combustion efficiency of PUF molding fuel is the one added with 8 wt.% WS since it could be fully combusted, having the lowest residue content, the highest comprehensive combustion characteristic as well as the lowest activation energy.
