the effects of carryover in steam boiler systems

The Effects of Carryover in Steam Boiler Systems

Effects of Carryover Boiler water carryover can cause deposits to form in valves, heat exchangers, turbines, and superheaters. If deposits are significant, heat transfer and/or turbine efficiency may be reduced. Additionally, carryover can strip away the protective magnetic layer on steam lines, remove the film formed by filming amine programs, cause erosion-induced corrosion, and result in
