VACUUM DEAIRING MACHINE Russian patent published in 2007 - IPC F22D1/50 

FIELD: deairing machines, possible use in power engineering.

SUBSTANCE: machine has tank-accumulator of deaerated water, centrifugal-vortex deaerator, drop deaerator, made in form of perforated pipe, positioned in steam space of tank-accumulator of deaerated water. Pipeline of the pump which drains deaerated water from tank-accumulator is connected to suction unit using recirculation pipeline, and on the end of this pipeline a nozzle is mounted, which is located in the center of suction branch pipe or pump or on recirculation pipeline a water-stream ejector is installed, suction branch pipe of which is connected to draining pipeline of accumulator-tank, and forcing branch pipe - to suction branch pipe of pump.

EFFECT: increased reliability of vacuum deairing plants of low productiveness for small boiler rooms.
