  • IMI CCI solves erosion problem at 500 megawatt power plant

    The boiler feedpump normally delivers feedwater from the deaerator (or feedwater bypass) to the economiser in high pressure conditions of up to 340bar/260oC (5000psi/500oF). When not providing the minimum flow at the pump suction to prevent the feedpump from overheating and cavitating, the recirculation valves must provide tight shutoff.Learn More

  • Practical considerations for modern BFW pumps

    Aug 11, 2015 · An alternative system calls for use a special valve sometimes known as a recirculation valve. With this setup, as the flow decreases, the valve automatically opens the recycle line, maintaining the minimum required flow at all times. As flow to the boiler increases, the recirculation valve automatically closes the recycle.Learn More
