The temperature and thermal stress of different air ways of purging plug were comparatively analyzed by means of finite element method. Combined with the physical properties of the air ways of purging plug, a set of field tests were carried out for the optimum structure. The results showed that the structure of air ways of purging plug had great impact on the thermal stress. In service process, the damage of the air way was mainly caused by tensile stress in axial direction. By evenly distributes the tensile stress in axial direction, the stress decreased by 40% compared with the original one, and thermal shock resistance of purging plug D with circular slit structure has been improved and also proved in the field test.
