摘　　要：通过数值计算与模拟分析,比对了大型900 t/d石灰双膛竖窑在“加长”与“加粗”两种技术方案上的优缺点,明晰了扩大窑径是石灰双膛窑大型化的可行路径。针对扩大窑径后导致的环形通道受力问题,开发了一种新型Z字卡扣砖腔复合通道结构,承载峰值应力可由0.46 MPa降低至0.33 MPa,降幅达28%。Through numerical calculation and simulation analysis,the advantages and disadvantages of the large 900 t/d lime double chamber vertical kiln in terms of"lengthening"and"thickening"were compared,and it was clarified that expanding the kiln diameter is a feasible path for the large-scale lime double chamber kiln.A new type of Z-shaped buckle brick cavity composite channel structure was developed to address the stress problem caused by expanding the kiln diameter.The peak bearing stress can be reduced from 0.46 MPa to 0.33 MPa,with a reduction of 28%.
