1. Steam condensers Functions: Lowers back pr. of turbine exhaust Enables recovery and recirculation of feed water Enables the removal of air and non- condensable gases

2. Elements of condenser

3. Types of condensers Jet condensers - Low level jet condenser - High level jet condenser - Ejector jet condenser Surface condensers - Shell and tube type - Evaporative type

4. Low level counter flow jet condenser

5. Low level parallel flow jet condenser

6. High level jet condenser

7. Ejector condenser

8. Surface Condenser - Shell and tube type condenser

9. Down flow surface condenser

10. Central flow surface condenser

11. Evaporative steam condenser

12. Advantages: 1.Lowers back pr. of turbine 2.High vacuum efficiency 3.Gives pure condensate 4.Saves cost of fresh water 5.Requires low power input for air extraction pump 6.Cooling of condensate is easily controlled 7.Low quality cooling water can be used Disadvantages: 1.Requires skilled workers 2.Requires large floor space 3.Large cooling water is req. - indirect cooling 4.Higher installation cost
