Co-combustion Kinetics Parameters of MSWI Fly Ash with Sawdust and Shale under Different Heating Rates and Atmospheres

The kinetic parameters for the co-combustion of municipal solid waste incineration fly ash, sawdust, and shale have been determined by a sync analyzer, aiming to simulate the manufacture of lightweight aggregates process. Experiments were carried out with about each 10-mg samples at different heating rates in air and argon atmospheres, respectively. The results indicate that behaviors of the mixture can be broadly divided into four separate events. The total mass loss reached the maximum at 20 K.min(-1). There appears to be no unanimous formula of the degree of the total mass loss in different gas atmospheres.
