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:
SATURATED STEAM VAPOR:
The steam sample cooler inlet and exit valves can be used to create various operating pressures in the cooler for producing samples from saturated steam vapor.
SUPER HEATED STEAM: Max. sample inlet temperature of 750°F (400°C). (See chart below.)
Proper installation of the Neptune sample cooler 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.
