Study Notes
Function of a Condenser
- A condenser cools and condenses exhaust steam from a turbine, converting it back into water.
- This process allows for the reuse of water in the steam cycle, increasing efficiency.
Operating Pressure
- Condensers typically operate at low pressures, often below atmospheric pressure, to maximize condensation and improve the thermal cycle.
Effect on Turbine Work Output
- Utilizing a condenser increases the specific work output of the turbine by decreasing the back pressure.
- Lower back pressure enables the turbine to extract more energy from the steam, improving overall efficiency.
Exhaust Steam Handling
- Exhaust steam from the turbine is directed into the condenser, where it loses heat and condenses into liquid water.
- The condensed water is then recirculated back to the boiler for reheating.
Vacuum Creation
- A vacuum is created in the condenser, which helps pull steam through the turbine.
- This vacuum is essential for improving steam expansion and enhances the turbine’s efficiency.
Cooling Water Circulation System
- The cooling water circulation system removes heat from the condenser, ensuring efficient condensation of steam.
- It typically involves water cooling towers, heat exchangers, or body of water, maintaining optimal operational temperatures.
