2012-12-2 · carryover of boiler water in the steam. Good operating practices, improved steam separators, and proper chemical control mini-mize this. Silica deposits in turbines, however, can occur even when boiler water carryover is negligible. The reason: steam selectively "picks up" silica from the boiler water, dissolves it, and carries it to the

Boiler Blowdown types and Boiler Blowdown calculation

Boiler feedwater usually contains a lot of dissolved and undissolved solids which is measured in total Dissolved Solids (TDS) contents in the boiler. These dissolved solids do not evaporate or escape during steam production and supply and settled at the bottomed the boiler shell or mud drum.These TDS causes serious trouble in boiler ie increase in scaling, corrosion, carryover localized

The Importance of Boiler Water and Steam Chemistry

Only mechanical carryover is affected by boiler design. Noninteractive gases such as nitrogen, argon and oxygen carry over almost entirely with the steam, having no relationship to moisture carryover. Excessive steam impurity concentrations can also be caused by feedwater and boiler water chemistries that favor volatile species formation.

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
