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

Method for removing scale on inner surfaces of boiler

An improved method for removing scale on inner surfaces of boiler outlet tube members is disclosed. The improvements reside in the steps, in combination, consisting of cutting either a main steam tube (4) or a tube member on the upstream of an inlet portion of a main steam tube (4) (for instance, a connecting pipe on the inlet side of a superheater), temporarily disposing a blocking plate (10

US4887431A - Superheater outlet steam temperature

A method and apparatus for controlling superheater outlet temperature of a steam generator utilizes a feed-forward control signal to control a spray attemperator. The feed-forward control signal is developed as a difference between a selected flow rate for steam required by a turbine operated by the steam generator, and a measured flow rate of steam from a steam drum above the steam generator.
