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

This can take place as a separate step or during acid cleaning. Both iron and the copper are removed from the boiler, and the boiler surfaces can then be passivated. In most cases, the copper is localized in certain tube banks and causes random pitting. When

Operation of Boiler and Conductivity in Drum Water and

Water chemistry sensors for both feed water and boiler need monitoring as any impurities in this gets concentrated and gets carried over in the steam. Conductivity controls for water blowdown in the drum type boiler are a method to remove such concentrate.

Boiler Water Conductivity Measurement Fundamentals

Boiler Water Conductivity Measurement Fundamentals As a boiler generates steam, any impurities which are in the boiler feedwater and which do not boil off with the steam will concentrate in the boiler water. Inside the boiler the heat generates steam bubbles : Aldo ZaffalonChapter 13 Boiler Blowdown Control | SUEZhttps://, the effects on internal conditions must be determined from the results observed during the turnaround for the specific unit. In plants with sodium zeolite softened makeup water, automatic control systems can maintain boiler water conductivity within 5
