| 中文摘要: |
| 研究导热介质钢球粒径和填充量对回转窑内橡胶裂解强化传热的影响。结果表明：当钢球的粒径为15 mm和体积率（占橡胶体积比率）为20%时，橡胶裂解的剩余固形物质量最小，对橡胶热裂解的强化传热效果最佳，橡胶裂解最为充分，抑制回转窑内壁结焦效果较好，且经济可行。 |
| 英文摘要: |
| The effect of steel ball size and filling amount on heat transfer enhancement by rubber cracking in rotary kiln was studied.The results showed that when the diameter of steel ball was 15 mm and the volume ratio （volume ratio of rubber） was 20%，the remaining solid mass of rubber cracking was the least，the heat transfer enhancement effect of rubber cracking was the best，the rubber cracking was the most full，and the coking inhibition effect of the inner wall of rotary kiln was good，and it was economical and feasible. |
