This Standard includes recommended practices concerned primarily with the prevention of water damage to steam turbines used for fossil-fuel-fired electric power generation. The practices address damage due to water, wet steam, and steam backflow into a steam turbine. The practices are applicable to conventional steam cycle, combined cycle, and cogeneration plants. The practices cover design, operation, inspection, testing, and maintenance of those aspects of the following power plant systems and equipment concerned with preventing the induction of water into steam turbines:(a) motive steam systems(b) steam attemperation systems(c) turbine extraction/admission systems(d) feedwater heaters(e) turbine drain system(f) turbine steam seal system(g) start-up systems(h) condenser steam and water dumps(i) steam generator sourcesAny connection to the turbine is a potential source of water either by induction from external equipment or by accumulation of condensed steam. The sources treated herein specifically are those found to be most frequently involved in causing damage to turbines. Althoughwater induction into the high and intermediate pressure turbines has historically been recognized as the most damaging, experience has shown that water induction in low pressure turbines can cause significant damage and should also be taken seriously.This Standard is not intended to impose new requirements retroactively for existing facilities.
