摘　　要：对某公司的高铝砖隧道窑实际生产数据进行测试与收集,在此基础上进行了热平衡计算,并对计算结果进行分析。该隧道窑热效率低于国内先进水平,主要原因是隧道窑燃烧不充分、散热损失大、烟气余热回收装置利用水平较低。可采用合理的空气系数、优化烧嘴结构和燃料种类、增强保温、改造或更换烟气余热回收装置、减少衬砖的数量等措施,提高隧道窑热效率。The actual production data of tunnel kiln for high alumina brick was tested and collected. On this basis, the thermal balance was calculated and analyzed. The results show that the thermal effi-ciency of tunnel kiln is lower than domestic advanced level. The burning process is insufficient, the heat dissipation is high and the level of waste heat recovery device is low. The thermal efficiency of tunnel kiln can be improved by using the reasonable air ratio, optimization of burner structure and fuel type, strengthening the measures of preserving heat and reforming or changing the waste heat recovery device, reducing lining brick.
