Problems caused by oil in boiler feed water system - GARD

Thin layers of oil at the boiler tubes or any of the directly heated surfaces of the boiler might cause local overheating of the material and possible damage to the boiler. There are many ways to prevent the entry of oil-contaminated feed water into the boilers, such as the use of observation tanks with detection-filter systems in hotwell tanks.

The Importance of Boiler Water and Steam Chemistry

The Importance of Boiler Water and Steam Chemistry. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified.
