Treatment apparatus and method for waste steam generator, and installation method of treatment apparatus for waste steam generator

A treatment method for a waste steam generator, the method comprising:

• providing a treatment apparatus including a cutting part for cutting a body of the waste steam generator, a driving part for driving the cutting part, a support frame for supporting the cutting part and the driving part, wherein the support frame is coupled to an outer peripheral surface of the body of the waste steam generator in a divided state, and the cutting part is driven and cuts the body in a state in which the support frame is coupled to the outer peripheral surface of the body, wherein the support frame comprises a plurality of divided portions, a coupling part for mutually coupling the plurality of divided portions in a state in which the divided portions are coupled to the cylindrical outer peripheral surface of the body in four locations, wherein the support frame comprises a main frame having a cylindrical shape in a state in which the support frame is coupled to the outer peripheral surface of the body, a rotation frame rotatably coupled to one surface of the main frame so that the cutting part and the driving part are mounted to the rotation frame, and a frame driving part for rotatably driving the rotation frame, and an electric supply module for supplying electric power to the driving part and the frame driving part, the electric supply module comprises an electric power supply rail coupled to the other surface of the main frame, a rail connection part maintained and rotated in a state of coming into contact with the electric power supply rail when the rotation frame is stopped and rotated, and a connection part connecting the rail connection part to the rotation frame, and the driving part and the frame driving part are electrically connected to the electric supply module through the rotation frame;
• applying electric power from the external electric source;
• supplying the applied electric power to the driving part for driving the cutting part and the frame driving part for driving the rotation frame through the electric supply module;
• and
• driving the cutting part mounted to the rotation frame in a state in which the rotation frame rotates to cut the body of the waste steam generator.
