SHELL & TUBE HEAT EXCHANGER

  1. 1. UNIT OPERATION 3 PREPARED BY: CANOY, CLAIRE E. YR & SEC. : 2B2-CHEMICAL ENGINEERING TECHNOLOGY
  2. 2. INTRODUCTION ● A shell and tube heat exchanger is a class of heat exchanger designs ● It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications.
  3. 3. INTRODUCTION ● As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. ● The set of tubes is called a tube bundle, and may be composed of several types of tubes: plain, longitudinally finned, etc.
  4. 4. OUTER DETAILS
  5. 5. INNER DETAILS
  6. 6. TUBE SHEETS
  7. 7. OPERATION Process stream flows through a coil heated by combustion of fuel in the furnace chamber.
  8. 8. Tie Rods & Spacers
  9. 9. APPLICATION and USES ● The simple design of a shell and tube heat exchanger makes it an ideal cooling solution for a wide variety of applications. ●One of the most common applications is the cooling of hydraulic fluid and oil in engines, transmissions and hydraulic power packs.
  10. 10. APPLICATION and USES ● With the right choice of materials they can also be used to cool or heat other mediums, such as swimming pool water or charge air. ● One of the big advantages of using a shell and tube heat exchanger is that they are often easy to service, particularly with models where a floating tube bundle (where the tube plates are not welded to the outer shell) is available.
