Boiler Water - FULTON 60E Operator, Service & Parts Manual

It is very important that a strict water management program is followed to ensure trouble free boiler operation.
The following are recommended for feedwater and for boiler water.

It is critical that the boiler pH be alkaline (9 -11) whenever water is in the boiler.
Daily boiler blowdown is essential to help prevent formation of deposits and reduce
Total Dissolved Solids (TDS).
Consult your Maintenance Manual for blowdown procedures.
Consult your Water Treatment specialist to establish the frequency and duration of
blowdown required to achive the required conditions.
Contamination from direct steam injection processes and leaks from indirect
systems must be avoided. Contamination in boiler feedwater / condensate will
result in unstable water levels foaming, carry-over and low water.
