The whole heat treatment of tower and spherical tank can be solved by burner, which is called diesel internal combustion method. Firstly，Wrap the tower and spherical tank with aluminum silicate insulation cotton. Weld the required temperature thermocouple by thermocouple spot welder according to the requirements. Then install the burner in the tower or spherical tank, and blow fire into its interior. We can control the workpiece heating process through controlling the size and direction of the fire. The power of the burner depends on the weight of the workpiece.
