What Is the Deaerator Mass and Energy Balance Boiler Feedwater Calculator?
Thermal deaerators strip dissolved oxygen and carbon dioxide from boiler feedwater by heating incoming water to saturation temperature with low-pressure steam.
Reducing dissolved oxygen to less than 7 ppb is critical to prevent severe pitting and oxygen corrosion in boiler tubes and economizers.
This calculator solves simultaneous steady-state mass and enthalpy conservation equations to determine stripping steam consumption, deaerated feedwater flow, and vent losses.
How Does the Deaerator Mass and Energy Balance Boiler Feedwater Calculator Work?
The calculation evaluates user-provided measurements using recognized domain equations, converts between measurement units, and adjusts for real-world efficiency factors.
