【Abstract】 Burning processes of six waste plastics were studied by using thermogravimetric experiments. The sample kinetic parameters of combustion reaction were calculated. The re- sults show that the burning processes of most samples chosen in this experiment are multistage, each stage has different kinetic parameters and the range of activation energies is 38.2~488.1 kJ/mol. Furthermore, it is expected that waste plastics may be burnt up rapidly and completely when used as fuel in metallurgical apparatus.更多还原
