Power plant mill exhauster main shaft breakage cause analysis

Abstract

Abstract:

Abstract:A power plant’s No.9 boiler No.1 mill exhauster main shaft was broken. By appearance inspection, widmanstatten structure, caused by overheat, was found at the sections varied area. Thus, the main reason caused breakage was determined that crack generated at sections varied area by concentrated stress while main shaft operating. Creaks extended gradually, and finally caused breakage.

Key words:

Keywords:mill exhaust, motor, main shaft, breakage, cause analysis
