CASE STUDY 02 05 Efficiency improvement of a 12MW turbine The customer is a copper manufacturing Industry in India. The turbine was sent to Triveni Refurbishing for repair, modification and efficiency improvement. Client’s turbine was an old running turbine sourced by them in 1983, which was sent to us in 2016 for refurbishing. The challenge was to modify the turbine in the existing turbine boundary conditions of the casing by redesigning it for higher efficiency which convert the low inlet steam parameters to high inlet steam parameters. CHALLENGE SOLUTION Triveni Refurbishing redesigned the steam path within in the existing turbine boundary conditions of the casing. The efficiency of the turbine improved by 16% and the payback period was just 6 months. “The TG has been roll
