  • 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


    Therefore, the boiler feedpump recirculation valve will be in the closed position for 90% to 95% of the time in most power plants. This valve will also have the highest differential pressure across the seat of any other valve in the plant. This makes the recirculation valve one of the most severe duty valves in a generating plant.Learn More
