Before you start taking water samples from those sources keep in mind that boiler feed and condensate water will all be pressurized and taken at high temperatures so be sure to exercise caution when taking them. Also never collect water samples while your feed water pump is
Samples andor sample points must meet the specific requirements (e.g. flow temperature velocity) of the individual tests or the continuous analyzers that utilize them. They must also allow the user to acquire samples in a safe manner; e.g. provide cooling as necessary route the sample to a protected area etc.
When taking a sample of boiler water it is important to ensure that it is representative. It is not recommended that the sample be taken from level gauge glasses or external control chambers; the water here is relatively pure condensate formed by the continual condensation of
Nov 01 2006 · Multiple sample coolers may be necessary to achieve the recommended sample temperature. Pitch the sample line downward at least 10° toward the sample outlet. Limit sample lines to 1/4 or 3/8 inch tubing to facilitate flushing. Design sample
