The utility model discloses a mounting structure of a buffer device for a thermal compensation sealing fin of an air pre-heater to enter and exit a sector plate, which comprises a hot end sector plate and the thermal compensation sealing fin of the air pre-heater, and is characterized in that the buffer device comprises more than two buffer blocks with the same structure and the same size; all the buffer blocks are installed on the radial side edge of the hot end sector plate and matched with the air pre-heater thermal compensation sealing piece, the longitudinal section of each buffer block is of an isosceles right-angle sector structure, the arc face of each buffer block is the face matched with the air pre-heater thermal compensation sealing piece, and the thickness of each buffer block is not smaller than 1/2 of the radius of the buffer block. And the buffer block is made of wear-resistant alloy. According to the installation structure, the situation that the sealing performance and the safety capacity of
