| Abstract: |
| Self-made rotary heat transfer device was applied to recover waste heat of high temperature centrifugal slag particles. Gas-solid phase flow was simulated by finite element analysis software and Euler model. The effects of inlet air velocity and rotating velocity of rotary kiln on heat transfer rate were investigated. The simulated result was verified by field test. The results show that the optimum heat transfer and dispersing effect are obtained under the conditions including rotator velocity of 16 r/min and inlet air velocity of 4.31 m/s with hot air temperature of 1 050 K. Numerical simulation results highly coincide to experimental study. |
