DEAERATION PLANT Russian patent published in 2010 - IPC C02F1/20 

FIELD: power industry.

SUBSTANCE: invention refers to power industry and can be used for thermal deaeration of feed water of steam boilers and make-up water of heat networks. Plant includes storage tank of deaerated water with vented steam branch pipe, deaeration device in the form of centrifugal-vortex deaerator with vented steam pipeline and dropping deaerator, deaerated water supply pipeline, deaerated water discharge pipeline, surface cooler of vented steam with cooling water supply and discharge branch pipes, with vented steam discharge pipeline and condensate discharge pipeline. Vented steam branch pipe from storage tank to vented steam cooler is deaerator of vented steam condensate, which is made in the form of vertical shell with overflow flanges overlapping some part of shell section. Lower part of shell is lowered to storage tank and has flat bottom made in the form of disc or cone bottom in the form of funnel. In lower part of shell there are openings through which vented steam flows, and below openings there located are condensate outlet hole, or lower part of cone bottom is changed to the pipe removing condensate from the plant.

EFFECT: development of deaeration plant at which vented steam condensate is not lost, but deaerated and used as demineralised water for feeding of steam boilers or in other processes.
