Application: Thermal spray is used to exclude oxygen boiler water (chemical make-up water and condensate) contained dissolved oxygen equipment to protect the boiler from oxygen corrosion. Second, the principle and function of the water supply and the water supply of oxygen is the main method utility boiler or industrial boilers to prevent corrosion in the pressure vessel, the gas dissolved in the water above the gas is proportional to the partial pressure of style, using thermal oxygen method , which uses steam to heat the water, feed water temperature increase, so that the water vapor partial pressure is gradually reduced at the end, the gas is dissolved in the water continuously escapes. When the solution is maintained under pressure while heating with steam water reaches boiling temperature, all of the water is water vapor, the partial pressure of the dissolved gas is zero, the water will no longer have the ability to dissolve the gas, i.e. the gas dissolved in the water, including oxygen may be excluded. Third, use: 1, deaerator, constant attention to maintain the pressure 0.02Mpa, working temperature is controlled within the range of 104.3 degrees. 2, the oxygen inside if there is corrosion, rust and coated with rust must be. 3, into the deaerator water must be demineralized water through the condensate. 4, into the deaerator water must be uniform, not a hit phenomenon, in order to facilitate increase equipment life. 5, deaerator and deaerator tank installation must be pressure test, the shell layer of mud coated asbestos qualified - (or other insulation layer) thickness of 80 -100mm. 6, stainless steel filler deaerator Raschig rings. 7, after the water treatment deaerator up its oxygen content ≤ 0.03 mg / l, in line with the water quality standards prescribed by the Ministry of hydropower. 8, deaerator generally 20% overload. Fourth, the oxygen tank deaerator storage tank is used for boiler feedwater peroxide has been lowered to ensure the safe operation of the boiler. Deaerator tank effective volume is generally 20 minutes boiler evaporation requirement, considering the large capacity unit boiler evaporation requirement 10 minutes. Five, six technical performance tables, automatic deaerator Technical Data Sheet
