Based on the static strength calculation, the fracture reason was examined for the last stage moving blades of an Extraction Condensing Steam Turbine (ECST) in a power plant. The calculations revealed that the original blade design was unreasonable, which resulted in the compound stress exceeding the material allowable stress. The study was focused on redesigning the broken moving blade by means of...
Numerical simulations of a flue gas turbine were conducted by using the software NUMECA. The influence of different moving blade installation angles was analyzed on the internal flow field, and the change of turbine's efficiency and mass flow rate was studied too. It is found that moving blade installation angle has great influences on turbine's performance. The results indicate that the optimal installation...
