  • Feedwater Heaters - Fluid Dynamics

    High Pressure Heater (HP): A Feedwater Heater located downstream of the boiler feed pump. Typically, the tube-side design pressure is at least 100 Bar, and the steam source is the high-pressure turbine. Intermediate Pressure Heater (IP): A Feedwater Heater usually located tube-side between the booster pump and the boiler feed pump.Learn More
