  2. Multi-pass shell and tube heat exchanger engineering-resource.com

  3. Components • A multi-pass shell and tube heat exchanger comprises: a shell having flanged ends; a removable tube bundle having a fixed tubesheet at one end and a floating tube sheet at the opposite end; a false tube sheet bolted to the floating tubesheet and having a passage hole aligned with each tube in the floating tubesheet to direct the flow of tube fluid; and a bonnet having a flange bolted to the outer portion of the false tubesheet. The use of the false tubesheet and attachment of the bonnet to the outer portion thereof maximizes available tube space. With the removal of the bonnet, and the false tubesheet, the bundle can be conveniently removed. engineering-resource.com

  5. The Shell and Tube (u-tube) is the most common type of heat exchanger used in the process, petroleum and chemical industry it contains a number of parallel utubes inside a shell. Shell Tube heat exchangers are used when a process requires large amounts of fluid to be heated or cooled. Due to their design, shell tube heat exchangers offer a large heat transfer area and provide high heat transfer efficiency. engineering-resource.com

  6. There are many different types or designs of shell and tube heat exchangers to meet various process requirements. Shell and Tube heat exchangers can provide steady heat transfer by utilizing multiple passes of one or both fluids. Shell and Tube heat exchangers use baffles on the shell-side fluid to accomplished mixing or turbulence. Without the use of baffles, the fluid can become stagnant in certain parts of the shell. engineering-resource.com

  8. Applications of S & T heat exchanger • . Parallel flow - the hot fluid and the coolant flow in the same direction. Counter flow - The hot fluid and the coolant flow in opposite directions. Cross flow - the hot fluid and the coolant flow at 90° angles (perpendicular) to each other. The four heat exchanger parts identified were: Tubes Tube Sheet Shell Baffles Single-pass heat exchangers have fluids that pass each other only once. Multi-pass heat exchangers have fluids that pass each other more than once through the use of U tubes and baffles . engineering-resource.com
