www.sfu.caShell and tube heat exchangers contain a large number of tubes packed in a shell with their axes parallel to that of the shell. Regenerative heat exchangers involve the alternate passage of the hot and cold fluid streams through the same flow area. In compact heat exchangers, the two fluids usually move perpendicular to each other.
Mechanisms of Heat Transfer
www.ou.eduShell and Tube Heat Exchangers Tube size: Length is standard, commonly 8, 12 or 16 ft. Diameter: most common 3/4 or 1 in OD Tube pitch and clearance: Pitch is the shortest center-to-center distance between adjacent tubes. Commonly 1.25 to 1.5 time the tube diameter. Clearance is the distance between tubes. It should be larger

5.1 Shell-and-Tube Heat Exchangers - Homepages at WMU
homepages.wmich.eduShell-and-tube heat exchangers can have multiple passes, such as 1-1, 1-2, 1-4, 1-6, and 1-8 exchangers, where the first number denotes the number of the shells and the second number denotes the number of passes. An odd number of tube passes is seldom used except the 1-1 exchanger. A 1-2 shell-and-tube heat exchanger is illustrated in Figure 5.19.
Specifying Shell-and-Tube Heat Exchangers - SciAm.com
stoppingclimatechange.comShell-and-tube heat exchangers are one of the most important and commonly used process equipment items in the chemical process industries (CPI). If you are working on a project during either the basic or the detailed engineering phase, there is a good chance that you will need to specify one or more shell-and-tube exchangers — and perhaps ...
API Standard 660
www.api.orgfor shipment of shell-and-tube heat exchangers for the petroleum, petrochemical, and natural gas industries. This standard is applicable to the following types of shell-and-tube heat exchangers: heaters, condensers, coolers, and reboilers. This standard is not applicable to vacuum-operated steam surface condensers and feed-water heaters.
Heat Exchangers - Jordan University of Science and Technology

Hairpin/Double pipe exchangers 2. Shell and tube exchangers 3. Plate and frame exchangers 4. Plate-fin exchangers 5. Spiral heat exchangers 6. Air coolers and condensers 7.
Heat Transfer in Food Processing - Prexams
cdn.prexams.comtube heat exchangers shown in Figure 4.8 are one shell pass with two tube passes, and two shell passes with four tube passes. 4.1.3 Scraped-Surface Heat Exchanger In conventional types of tubular heat exchangers, heat transfer to a fluid stream is affected by hydraulic drag and heat resistance due to film buildup or fouling on the tube wall.
Design Considerations for Compact Heat Exchangers
www.heatric.comCircuit Heat Exchangers since 1985, when Heatric was first established in Australia. The term ‘compact’ is often confused with meaning small; however, individual heat exchangers can be in excess of 8 metres length and 100 tons weight; assemblies can comprise tens of exchangers, so compact heat exchangers can be of appreciable size.
