heat exchangers. The most common uses are for difficult-to-handle fluids with no phase change. However, the low-pressure-drop characteristics are beginning to promote some use in two-phase flow as condensers and reboilers. For this purpose the two-phase fluid normally flows axially in a single pass rather than spirally. 52.1.4 Air-Cooled Heat Exchangers
allow the heat exchanger shell to operate at a negative pressure which may cause condensate to be held up in the shell. During light load, the heat exchanger will have a layer of steam at the top and air under the steam to provide just the right amount of heat. The vacuum breaker should be mounted on a vertical pipe 6 to 10 above the topping to provide Vacuum Condensers Vacuum Heat Exchangers Sealant heat exchanger:Use a heat exchanger in full recovery systems to cool the sealant liquid before recirculating it back into the pump; Inter-stage heat exchanger:A condenser placed between two pumps or a booster and a pump to cool the process stream; After-condenser:A condenser placed after
Heat Exchangers and Condensers. 90-10 and 70-30 Cu-Nis are widely used in tubular heat exchangers and condensers for seawater, brackish water and fresh water. Considerations for High Performance. Power generation at the TVA Colbert facility.
