Statistics show that as a power plant reaches its rated lifetime, the number of its forced outages begins to grow substantially, and its reliability and availability fall.
Simultaneously, in the operation process the turbine’s efficiency lowers more and more, even though it is partially restored at overhauls.
It is possible to find steam turbines that have successfully operated for 40 – 50 years or more. Lately, power equipment lifetime extension has substantially gained in its scope and acquired much more serious significance. Continue reading “Retrofitting – When Steam Turbines Age”
