Abstract: In order to deal with the waste tires with strong anti-degradation and the waste heat of blast furnace slag, a fluidized bed for cracking waste tire particles with waste heat from blast furnace slag was designed. The operating gas velocity and size of fluidized bed were determined according to the characteristics of waste tire particles and blast furnace slag particles. The gas velocity of the fluidized bed was determined to be 2 m/s in cold state experiment, and the oil yield of the fluidized bed could reach 42% in hot state experiment. The rationality of the design parameters of fluidized bed was verified by cold and hot experiments.

Keywords: waste tire particle; furnace slag; waste heat; fluidized bed; equipment design
