Condenser in a Thermal Power Plant
In a thermal power plant, the steam pressure is less than that of atmosphere in the condenser. Let's understand why:
Explanation:
- The thermal power plant works on the Rankine cycle, which is a closed cycle with the four main components - boiler, turbine, condenser, and pump.
- The boiler generates high-pressure steam by heating water using coal or other fuels. The steam is then sent to the turbine to generate electricity.
- After the steam has passed through the turbine, it enters the condenser.
- The condenser is a heat exchanger that cools down the steam to convert it back into water. This is done by circulating cool water from a nearby source (such as a river or lake) through the tubes of the condenser.
- As the steam comes into contact with the cool tubes, it condenses into water and releases heat to the water in the tubes.
- The pressure in the condenser is less than that of the atmosphere, which means that the water can exist in liquid form at a relatively low temperature.
- The water is then pumped back to the boiler to repeat the cycle.
Conclusion:
Therefore, in a thermal power plant, the steam pressure is less than that of the atmosphere in the condenser because the steam has lost pressure and temperature after passing through the turbine, and it needs to be cooled down and converted back into water before it can be reused.

In the condensor the steam is cooled down to very low temperature thus the steam is converted into water and expansion of steam takes place which reduces the pressure and helps it to form water . so the steam pressure is less than that of atmosphere
