2.17 CLEANINg STEAM LINES AND PRESSURE VESSELS
During the first week of boiler operation, clean all oil and dirt from the boiler, the steam line and
condensate return line.
(a)
Disconnect the condensate return pipe adjacent to the condensate return tank.
(b)
Direct the returns to a floor drain or other safe discharge point and make safe.
(c)
Leave in this position for one week to allow all impurities to flush through.
(d)
Drain the boiler completely each day.
(e)
After the week is completed, drain and flush the condensate return tank, removing all installation
sediment. Reconnect the condensate return pipe to the condensate return tank.
2.16 COMMISSIONINg THE BOILER - continued
(n)
Adjust the steam pressure control to suit the boiler application. It should be borne in mind that
boiler are designed to operate most efficiently at their maximum operating temperature. When
boilers are to be operated below a pressure of 80 psi (5.5 bar) consideration should be given to
the fitting of a pressure reducing set (see Section 2.8 - Steam Safety Valves).
If the pressure control is fitted with a differential scale:
(see OEM literature in section 5)
(i)
Set the main scale pressure to the pressure
indicated on the boiler data plate.
(ii)
Set the differential scale to it's minimum pressure.
If the pressure control has a fixed differential,
e.g. no adjustable differential scale, set the main
scale to the maximum pressure required.
Note: When boilers are fitted with a sequence control:
(i)
Set the main scale and differential scale as above.
(ii)
Set the set-back pressure control to the required
set-back pressure.
