Boiler deaerator systems remove undissolved gases (carbon dioxide, oxygen, and air) that cause many component or system failures in boiler feedwater systems. Undissolved oxygen is a major cause of corrosion in boiler deaerator system components. Carbon dioxide forms corrosive carbonic acid damaging to heat transfer equipment and piping. Non-condensable air reduces heat transfer efficiency of boiler aerators.
Rexarc, with generations of excellence in producing high-performing steel tanks, fabricates high-quality boiler deaerator shells for industrial and commercial boiler systems. Produced custom to your specifications, units are offered in both horizontal and vertical orientations.
At Rexarc, we fabricate and deliver following types of boiler deaerator shells to your specifications.
In tray type deaerator, the deaeration section is mounted over the horizontal feedwater storage section or compartment. These deaerator systems assure guaranteed removal of dissolved oxygen in excess of 0.005 cc/liter from 5 to 100% of the capacity of the deaerator. The systems can handle water capacities up to 1,000,000 lbs/hour. We can provide these tray type deaerator systems in different configurations – flanged heater section, standard tank car, and vertical single tank.
These are single horizontal vessels fitted with a deaeration section and a preheating section. They reduce the dissolved oxygen content to 0.005 cc/liter and guarantee 100% removal of carbon dioxide. These spray type deaerators can be availed in different capacity ranges and assure low vent losses.
These deaerator systems are known as vacuum degasifiers, and are largely used in applications where there is no scope of heating water to 102 degrees to 104 degrees Celsius due to the unavailability of steam. We can provide vacuum type deaerator systems in compact sizes with control unit, tank, heat exchanger, and cooling water system in one unit. It can be provided in different flow rates.
Rexarc works with boiler manufacturers to fabricate and build deaerator shells to custom designs. As an ASME vessel fabrication and value-add leader, we are comfortable manufacturing boiler deaerator shells to meet your specifications.
