Boiler Blowdown - Conductivity Check
Boiler surface-blowdown trigger - when conductivity exceeds 3 000 µS/cm for auxiliary boilers.
Action
Within range
Formula, assumptions, and limits
High TDS → foaming + carryover, superheater tube failure. Bottom blowdown for sludge; surface for TDS. Daily check + dosing ~10-20 ml/tonne caustic.
