6.2 Procedure to take boiler samples
1.
The cooling water stop valve (3) and the sample needle valve (2) should be closed.
2.
Open the cooling water valve slowly in order to avoid water hammer damaging, until the
input pressure reaches its limit.
3.
Open the needle valve slowly so that flashing does not occur. Allow to run approximately
10 seconds until fresh sample is drawn.
4.
Adjust the sample outlet temperature (if necessary), by regulating the sample needle valve
and the water valve.
5.
Make sure that there is an adequate equipment to collect the sample in place.
6.
After the sample collection, close first the sample valve and then the water valve but only
after a small period of time in order to condense or cool the remaining steam inside the
sample cooler.
6.3 Periodical checking
•
24 hours after the start up, it is recommended to check the pipe connections for leaks and
retighten the connections if necessary.
7. Maintenance

The sample cooler don’t need any specific type of maintenance. Regular inspection may
be recommended by local authorities according to specific or general pipe and/or vessels
assembly procedures.
