Dry Cycle
20.
Manually turn the handle on cycle selector valve B so that the arrow on the handle points toward the steam separator
(
). This will open the valve to the dry cycle.
Cycle selector valve B will be HOT.
21.
Open collection header dry cycle inlet valve G and close collection header wet cycle inlet valve F for the installed SCs
(
or
).
22.
Open steam inlet valve A to start the dry cycle (
).
During the dry cycle, saturated steam is diverted to the steam separator, which removes up to 99.8% of moisture. A steam trap
downstream of the sample cylinders discharges condensate without allowing the escape of live steam. The steam trap and
continued input of heat allow steam to be contained, increasing the temperature at which the cylinders are maintained. The
cycle further heats the system to facilitate "baking" of any residue remaining in the sample cylinders.
23.
Allow the dry cycle to run until the SCs are clean.
The time required to completely clean the sample cylinders is dependent on the set temperature of the steam generator, the
water inlet pressure, the type of contaminant(s), and the number of sample cylinders.
24.
Once the sample cylinders are considered clean in accordance with the end user's specifications, close steam inlet valve
A (
). This ends the dry cycle.
25.
Open collection header wet cycle inlet valve F and close collection header dry cycle inlet valve G for the installed SCs
(
or
).
The sample cylinders must be drained prior to disconnecting the quick-connects. Failure to drain the sample cylinders prior to
disconnecting the quick-connects may result in damage to the equipment and/or injury to the operator.
26.
Close steam header isolation valve C on each steam header used (
or
).
27.
If a vacuum will not be pulled on the SCs, continue to step 28. If a vacuum will be pulled on the SCs, proceed to step
35.
