Evaporator Mass & Steam Balance Calculator
Calculate water evaporation rate, concentrate flow and steam consumption for falling-film evaporators with single-effect, multi-effect or MVR designs.
Inputs
Illustrative examples:
Example feed 12→48% TS
WPC 10→25%
WMC 12→50%
SE = kg water evaporated per kg steam. Presets are assumptions; use measured or supplier data for the defined duty.
12 is an illustrative reference, not a plant guarantee. Excludes pumps and other auxiliaries.
Leave blank if unknown. Enter zero only if justified; include relevant feed heating and other steam duties.
