Test Your Knowledge: Steam Turbine Rotor Vibration

Steam turbine rotors are susceptible to bending during some operational evolutions, which can lead to excessive vibration and ultimately failure. Rotor bending that results in premature failure of steam turbine blades and other internal components is one of the most serious problems experienced in power plants. The problems often reduce plant availability by limiting generation […]

Duke Energy Florida said it would commission the first unit of its two-unit Citrus gas-fired combined cycle plant in September 2018.
