Fulton Boiler FBS Series
27 FBS 01/05
consulted. Ensure there are no accumulated deposits of sludge in the bottom of the boiler.
(e) Remove the feedwater disperser inspect and clean.
(f) Replace the man hole and hand hole door gaskets, refer to Section
FITTING NEW GASKET
for fitting procedures.
(g) Open the boiler front access door with the burner mounted on it as described below. It will be
necessary to disconnect the gas supply from the gas train and oil supply from the oil lines to allow
the door to swing open.
(h) Where retarders are fitted they should be removed-some burning of the retarders at the inlet end
is normal.
(i) Remove the rear smoke box access doors.
(j) Brush through the tubes to remove any deposits from the products of combustion.
(k) Using a wire brush, clean the internal surfaces of the furnace and the face of the front tube plate.
Pay particular attention to the tube ligaments (the spaces between adjacent tubes).
(l) Inspect the tube ends for any signs of splitting or burning. These are symptoms of gas reburning
in the tube ends as a result of poor combustion, e.g. carbon monoxide carry-over. If the tube ends
exhibit these signs, consult Fulton Boiler Works.
(m) Clean out the rear smoke boxes to remove the deposits brushed through from the tubes.
IMPORTANT
Ensure that the rear smoke box drain connections are clean and free from deposits. This is
particularly important on oil fired boilers because of the acidic nature of the condensate
formed.
(p) Inspect the door seal for signs of wear and replace if necessary. The first indication of a worn door
seal would be evident by signs of leakage around the external periphery of the door.
WARNING
When handling ceramic fibre always follow the local regulations regarding such materials,
including the use of breathing apparatus, suitable body protection and protective gloves.
(q) Examine the internal surface of the door lining for defects. Small repairs may be carried out by
cutting out the defective area and replacing with new fibre, ensure the correct adhesive is used.
(r) Examine the end of the burner blast tube where it extends through the door into the furnace. Clean
off any deposits, paying particular attention to the internal lip where deposits can cause irregular
flame patterns.
(s) Inspect the rear smoke box door seals for deterioration and replace if necessary.
(t) Close the hinged front access door by reversing the opening procedure.
(u) Re-connect the gas/oil connections.
(v) Drain and flush the feedwater/ hotwell tank, clean any filters and the strainer in the feedline before
the pump.
(w) Drain and flush out the blowdown separator.
(x) Carry out routine maintenances to the burner as detailed in the manufacturers installation and
maintenance instructions.
NOTE
Depending upon the mode of operation, it may be found that the six monthly interval can be
extended, possibly to an annual service. It is strongly recommended, however, that the
interval should be 6 months from initial start up until such times as a ‘pattern of use’ and the
condition of the boiler after a typical 6 months can be established.
ANNUALLY
It is a requirement of the Factories Act and Pressure Systems Regulations that the boiler is internally
inspected and re-certified at not more than 14 month intervals.
It is normal practice to carry out an annual service during which your insurance surveyor would attend
to carry out the statutory inspection. The scope of a full insurance strip-down is such that it should
only be attempted by persons competent to do so who have had the necessary training, and have the
required test equipment. Fulton Boiler Works can offer this service if required.
The engineering surveyor may require the removal of the ceramic fibre insulation around the
periphery of the front tube plate to facilitate inspection of the shell to tube plate weld. The standard
Fulton service kit includes replacement ceramic fibre log material 50*50*150 mm which must be
glued in place with the adhesive supplied. It is vital the material is fitted ensuring the ends of the fibre
face into the centre of the boiler.
