Abstract:
PURPOSE:To efficiently remove iron oxides from feed water, by providing permanent magnets in the deaeration chamber of a deaerator to which drained water from a high-pressure feed water heater is returned. CONSTITUTION:A feed water pipe 21 connected to a low-pressure feed water heater and a drain pipe 18c for a high-pressure feed water heater are connected to the top of a deaerator 10. A heating steam pipe 25 coupled to a boiler is connected to the side of the deaerator 10. A plurality of permanent magnets 27 are provided at the bottom of a deaeration chamber 28.
