BWX Technologies, Inc. specializes in advanced feedwater heaters, which are essential shell-and-tube heat exchangers utilized in power plants to preheat boiler feedwater. By utilizing bleed-off steam from high-pressure turbines on the shell side, these heaters effectively warm the feedwater flowing through the tubes, thereby enhancing the overall thermal efficiency of the plant. The design incorporates both low-pressure and high-pressure feedwater heaters strategically placed within the thermodynamic cycle—low-pressure units located between the condenser and deaerator, and high-pressure units situated between the deaerator and steam generator. The optimal number of each type of heater is determined by cycle optimization, aligning with various turbine extraction points to maximize energy recovery. This regenerative heating process significantly reduces the thermal energy required for electricity generation, making feedwater heaters a crucial component in improving power plant performance and sustainability.
