| Abstract: | The deformation of the cylinder and the damage of the high pressure steam honeycomb duct of the high pressure steam turbine in a PTA plant were simply presented, the mechanism of the cylinder deformation and honeycomb duct damage were analyzed. Finally, a method for measuring the turbine was proposed on the basis of the measured deformation data and the changed honeycomb duct structure, and the result was satisfactory. |
