WATER SOFTENER and CHEMICAL TREATMENT
The chemicals required to operate the water softeners and chemical treatment plants
CAN BE SUPPLIED by Fulton. It is the responsibility of the operator to ensure adequate supplies of chemical
are available at all times (including commissioning). Costly repairs could be required should the plant operate
without chemicals or the wrong dosage of chemicals.
The Fulton Warranty does not cover damage or failure that can be attributed to excessive
corrosion, scale, fouling or a poor water treatment regime.
The quality of the water used in the boiler will affect the life and performance of the boiler.
Feedw
ater contains solids and dissolved gases, these may promote encrustations of scale;
foaming, priming, surging; corrosion and pitting; or caustic embrittlement. To prevent this
happening, it is strongly recommended that a reputable water treatment company is
consulted prior to commissioning the boiler.
Note: See Ap
pendix A - TI-139-Recommended Water Conditions.
Connect the fe
edwater pump discharge to the check valve inlet with 25 mm bore pipe. The pump
suction pipework must remain at 25 mm minimum diameter and be as short as possible. Install
the stop valve supplied between the pump and the check valve. The check valve must be
positioned so that it is below the internal water level of the boiler and should be installed at least
1 m after the feedwater pump. The reason for this placement position is that the check valve is
designed to have water on both sides to enable it to function correctly.
It is essential to protect the feedwater pump from damage by foreign matter, a strainer must
be
fitted in the pump suction pipework.
Care should be taken to ensure the pipework is properly aligned and not placing any st
rain upon
the feedwater pump.
Note: The
boiler feedwater pump may contain an inhibitor and this should be flushed from the pump prior to fitting
the pump to the boiler.
Failure to do so may result in water bounce or foaming due to the inhibitor forming a seal in the boiler.
Note: If th
e boiler is to be operated with little or no condensate return, consideration should be given to pre-
heating the feedwater. If in doubt consult Fulton Ltd.
