2. Content Shell and TubeOperationPlenumSourcesApplicationsBaffles Types of Heat Exchangers

3. Operations Tube side Shell side Two fluids, of different starting temperatures, flow through the heat exchanger.

4. Operation The fluids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes

5. Operation In this way, waste heat can be put to use

6. Shell and Tube The use of the shell is to contain the fluid that is used to cool The use of the tubes is to transport the fluid or gas that is being cooled

7. Shell and Tube Tubes are subjected to extreme working conditions. It should be Compatible with shell and tube side fluids Good thermal conductivity Resistant to corrosion (because of high ph) Materials usually of high quality. Most likely metals Strong

8. Shell and Tube Consequences of wrong choices: Contamination of both fluids Leak Loss of Pressure

9. Shell and Tube Common materials for shell and tube Carbon steel Aluminium brass Alloy of Copper and Nickel Titanium

10. Plenum Spread the fluid /gas that enters the exchanger evenly so that the cooling process is more even

11. Baffles Baffles direct the flow of fluid through the shell side so the fluid does not take a short cut through the shell side leaving ineffective low flow volumes

12. Baffles Causes shell-side fluid to flow along tube fieldineffective low flow volumes Increases velocity and effectiveness of heat transfer of the exchanger

13. Types of Heat Exchangers

15. Applications Fossil fuel and nuclear based power plants Heat water into steam using heat exchanger Steam is used to drive turbines to produce power

16. Applications To condense or to cool high temperature gas into liquid form Using water as source of cooling and inserting the hot gas to the tube- side

17. Applications To cool fluid in ships and boats Using water from the sea as source of cooling Such as air-conditioning

18. Applications Caribbean and Middle EastLimited fresh water for coolingSea water is used for cooling
