  • US4582027A - Economizer recirculation for low-load

    A recirculation apparatus is employed to recirculate a portion of the feedwater in a vertical-tube economizer to reduce the likelihood of reverse flow and steaming at startup and/or low load. A recirculation valve, opened at low load, directs part of the water from the economizer outlet back to the inlet of the boiler feed pump via a deaerator.Learn More

  • 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
