On-line removal of copper deposits on steam turbine blades

摘要

This invention relates to an on-line process for removing copper deposits from the blades of the rotor of a steam turbine in systems, particularly condensing steam turbines. The process comprises adding an oxime to an appropriate injection point of an electric generating power plant powered by a steam turbine, where the power plant comprises a pre-boiler system, a steam generator, a steam turbine, a condenser and an electric generator.
