Feedwater Heating Enhancing Power Plant Efficiency Through Thermal Recovery
Time :Apr 02 2026

Steam extraction unlocking hidden energy

Recovering heat from turbine stages

Extraction steam from different turbine stages contains valuable thermal energy that would otherwise be wasted. By redirecting this steam into the feedwater heater, the system captures and reuses this energy effectively.

Improving thermal cycle efficiency

Preheating feedwater reduces the temperature gap inside the boiler, which increases the efficiency of the overall Rankine cycle.

Reducing unnecessary heat input

Less additional fuel is required to reach the desired steam temperature, leading to lower operational costs.
