Abstract

In the paper the application of ToF laser scanner in measurements of geometrical parameters of a boiler drum in power plant is presented. The point clouds acquired by the scanner have been subjected to a set of post-processing operations that provided the most important geometrical parameters of the drum. The obtained data can be used for optimization of the process of mounting a mechanical steam-water separation during renovation works. Currently used separations are tightly placed in boiler drum, so the welding process is not required anymore. This approach saves the time of renovation works, but the geometry of a separation has to be precisely matched against the geometry of the drum to ensure the tightness of connection and, in consequence, to ensure stability of steam parameters (pressure and temperature).
