Maintenance and Repair
by William P. Sanders

Turbine Steam Path provides analysis to repair and refurbishment options currently accessible that will keep turbines operating with high levels of availability and improved efficiency.

Also provided are details on estimating financial penalties associated with leakage from damaged turbines, which can reduce the cost of power.

A full analysis of quality and inspection of manufactured elements to replace damaged components is included as well.
