| The boiler pre-pump can also improve the economy of the deaerator. The pre-pump and the feed water pump are operated in series to ensure the economy of the deaerator during sliding pressure operation. At the same time, after the feed water is pressurized by the pre-pump, its outlet water pressure head is higher than the limited cavitation margin required by the feed water pump and the additional vaporization pressure head at a small flow rate, which effectively prevents the cavitation of the feed water pump. |
