  • Improve Availability and Operational Flexibility

    Boiler Feedpump Recirculation Valve The boiler feedpump recirculation valve faces some of the toughest conditions of any control valve in a power plant. The boiler feedpump takes its suction from the deaerator at relatively low pressure, and increases the pressure to approxi-mately 10 percent above the main steam pres-sure.Learn More

  • power boiler recirculation systems

    The recirculation pump operates in parallel with the main boiler feed pump, and thus handles only recirculated fluid rather than a combination of recirculated and through flow that would be required by a series located pump. The actual on line recirculation pump power is approximately 100 horsepower.Learn More
