The liquefied petroleum gas (LPG) cylinder incineration test is an important part of the cylinder periodic inspection to clean up the residual gas and ensure the safety of subsequent inspection items. However, the cylinder needs to be incinerated several times due to the uneven temperature distribution of the cylinder, leading to low incineration efficiency and waste of energy. In this study, a cylinder incineration test is experimentally investigated and a CFD model is established to analyze the influence of incinerator structure parameters and cylinder types on the temperature uniformity of the cylinder. The results show that the temperature distribution of the middle surface of the cylinder is most uneven. With the increase of the burner nozzle diameter and the incinerator diameter, the standard deviation of temperature decreases at first and then increases, and the minimum is reached at 150 mm and 530 mm, respectively. The optimized design is found to have a better temperature uniformity of the cylinder with the burner nozzle angle of 0°. The optimal incinerator diameter for different types of LPG cylinders is different and decreases as the cylinder diameter decreases.
