摘要：
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 © 2024 Science Press.
