abstract

Silt particles flow through hydro turbines cause erosion in turbines and due to silt efficiency of turbine reduces, vibrations produces in hydro turbines components and finally breakdown of hydro turbines take place, which causes immense losses. In the present study experiments were carried out to study the effect of silt size, silt concentration, jet velocity and operating hours on performance of Turgo impulse turbine. Silt was collected from Dehar power house (India). It has been found that erosion strongly depends on silt parameters (silt size, silt concentration) and operating parameters (Jet velocity and operating hours of turbine). A correlation has been developed as a function of jet diameter, silt parameters and operating parameters of percentage efficiency loss in Turgo impulse turbine.
