In order to restrain cement kiln shell’s thermal loss and potential safety hazard, composite design is employed of working layer, thermal-preservation layer and thermal insulation layer. Thermal-preservation layer’s boundary and strain is analyzed and overall thermal conductivity is calculated. The result shows that sinusoidal curve boundary combination between working layer and thermal-preservation layer, slopeshape with angle of 135 degrees between thermal-preservation layer and thermal insulation layer could relieve strain concentration. Composite mullite brick comprehensive thermal conductivity decreases from the working layer 2.74W·m-1·K-1 to 1.50W·m-1·K-1. When applied in cement kiln, temperature of kiln shell is lower 50°C to 70°C than using normal bricks.
