Study Notes
Condenser in a Power Plant
- The main function of a condenser in a power plant is to condense the exhaust steam from a turbine, converting it back into liquid water, allowing the reuse of the steam in the cycle.
- A condenser usually operates in a vacuum state, which is below atmospheric pressure.
- The use of a condenser increases the specific work output of a turbine, as it allows the turbine to exhaust into a lower pressure, resulting in a greater pressure ratio and increased efficiency.
Cooling Tower in a Power Plant
- The purpose of a cooling tower in a power plant is to dissipate the heat rejected by the condenser to the atmosphere, allowing the condenser to maintain a low temperature and pressure.
Operation of a Condenser
- The volume collapse of steam into water during condensation plays a crucial role in the operation of a condenser, as it allows the condenser to maintain a low pressure and enables the efficient heat transfer and condensation of steam.
- A condenser typically operates at a low pressure, usually below atmospheric pressure.
