Book Description
The experimental studies were performed in the heat transfer and fluid flow facilities of the Pacific Northwest Laboratory operated by Battelle Memorial Institute. The test section was installed in the high pressure heat transfer apparatus, a stainless steel loop which has a design rating of 2500 psig at 650°F. Recirculating flow was provided by a 250 gpm, 1450 ft head centrifugal pump, and the flow rate through the test section was adjusted by air-operated control and bypass valves. The loop was pressurized and controlled at the desired operating pressure by a feed-and-bleed arrangement using a positive displacement 3-piston injection pump and an automatically controlled air-operated bleed valve. All feed water passed through a deaerator, a deionizer, and a filter before entering the injection pump. Injection pump pulsations were dampened with a 10-gal accumulator. During operation of the third test section, all recirculating water passed through a porous metal filter unit having a 10 micron removal rating. A three-way valve downstream of the test section was used to adjust the loop flow split through and around a water-cooled heat exchanger. The valve was automatically controlled to maintain the desired water temperature entering the test section.
