: Vern, The readings are for the boilers except for the condensate cond. and the FW cond.. The condensate is taken from the return line to the deaerator and the feedwater is from the deaerator. When contaminated the F.W. and condensate condutivity are high. The blr. conductivity stays in range w/o excess blowdown. The header pressure is 100 psi. Drum press. is 110-125 depending on the load. Condensate has not been checked for sulf. or phosphate. All the heat exchangers are ok. Thanks

Scott, I think the first thing to check is the condensate for boiler water
chemistry residuals. If you have readings for sulfite or phosphate or a reading
on the particular chemical you use, then you have boiler water carryover. If
none of those are present, then you have a leak in a process somewhere.
