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
Types of condensers
• Jet condensers- Low level jet condenser- High level jet condenser- Ejector jet condenser
• Surface condensers- Shell and tube type- Evaporative type
Advantages:1. Lowers back pr. of turbine2. High vacuum efficiency3. Gives pure condensate4. Saves cost of fresh water5. Requires low power input for air extraction pump6. Cooling of condensate is easily controlled7. Low quality cooling water can be usedDisadvantages:8. Requires skilled workers9. Requires large floor space10. Large cooling water is req. - indirect cooling11. Higher installation cost
