Turbine Abrasion and Agoyan Dam

Turbine Abrasion and Agoyan Dam...

Detailed Description

A severely abraded turbine that was removed from service at the Agoyan hydroelectric power plant, which is sited 5 km east of Tungurahua volcano. Tephraladen water filtering through the turbines has necessitated the replacement of four turbines in 21 years. The Agoyan Dam and its (orange) floodgates are designed to let highly turbid water bypass the turbines so as to avoid accelerated wear of generation components
