Tank vent BDA-2 is part of a special installation of deaerator DA – 5/2, which removes corrosive gases (oxygen and free carbon dioxide) from feed water in steam boilers and feed water in heating systems.
Tank deaerator BDA-2 is a horizontal, cylindrical vessel with elliptic bottoms (allowed conical with sloping top welded), pipe entrance and exit of the working environment, special manhole and openings, which are designed for the installation of vent column.
In the deaerator tank BDA has the necessary supply of water for a few minutes of uninterrupted boiler operation.
This product is submerged bubbling device (the third, optional stage water purification). Water intended for deaeration, is fed into the column deaerator through nozzles, where she gradually overcomes inkjet and bubble level, is heated and is treated with steam. Then the treated water jets drains into the tank, it is aged and is discharged from the deaerator through the nozzle.
Deaerator tanks BDA-2 are not subject to FNP (Federal norms and rules in the field of industrial safety "Rules of industrial safety of hazardous production facilities that use equipment operating under excess pressure"; approved by order of the Federal service for ecological, technological and nuclear supervision from March 25, 2014 No. 116 instead of PB 03-576-03 to look). Manufactured according to GOST R 52630-2012 "Vessels and apparatus welded steel. General technical conditions".
