Installation
Proper installation requires valves on
sample inlet and cooling water inlet for
hot water service. An additional valve
must be installed on the sample outlet
for all vapor or steam services to obtain
required operating pressures in the coil.
Proper installation in superheated steam
service also requires precooling the
sample to 750°F, the maximum design
operating temperature of the Neptune
Sample Cooler.
Precooling can be accomplished by
installing a pipe between the main steam
header and the sample cooler to radiate
excess heat. The length of the pipe is
determined from the chart at right.
Performance
Assuming a coolant inlet of approximately 55°F (12°C) and exit of approximately
120°F (50°C) and a sample exit of approximately 110°F (43°C), the cooler will provide
performance approximately per the ranges described below:
HOT WATER SAMPLES:
• At 250°F (120°C), approximately 1500 CC/Min of sample will be produced using
1 gallon per minute of coolant.
• At 700°F (370°C), approximately 950 CC/Min of sample will be produced using
2.5 gallons per minute of coolant.
SATURATED STEAM VAPOR: The sample inlet and exit valves can be used to create various
operating pressures in the cooler for producing samples from saturated steam vapor.
• At 175 psia operating pressure, 640 CC/Min of sample can be produced using
approximately 3.0 gpm of coolant.
• At 25 psia operating pressure, 300 CC/Min of sample can be produced using
approximately 1.5 gpm of coolant.
SUPER HEATED STEAM: Max. sample inlet temperature of 750°F (400°C). (See chart below.)
• 1,000 psia cooler operating pressure produces 640 CC/Min of sample at
3.5 gpm coolant flow.
• 20 psia cooler operating pressure produces 315 CC/Min of sample at
1.75 gpm coolant flow.
