One.Foreword

DeoxygenatorBoilerOne of the key equipment for heating systems。

In the boiler feed water treatment process, deoxygenation is a very critical step. Oxygen is a primary corrosive substance in the feed water system and boiler. Oxygen in the feed water should be removed quickly, otherwise, it will corrode the boiler feed water system and components. The corrosion will produce ferric oxide that enters the boiler, sediment or adhere to the boiler tube walls and heating surfaces, forming difficult-to-dissolve iron scale that leads to poor heat transfer. Moreover, corrosion can cause pitting on the inner wall of the pipes, increasing the resistance coefficient. In severe cases of pipe corrosion, even pipe accidents may occur. The national regulations stipulate that the evaporation capacity is greater than or equal to2Steam boilers with output of more than or equal to tons per hour and water temperature95℃All of our hot water boilers are deaerated. Over the years, numerous boiler water treatments have been seeking a cost-effective deaeration method for constant temperature water. Lianyungang Jiusheng Power Auxiliary Equipment Co., Ltd. has years of experience in designing and manufacturing deaerators.JSNCYIntegral Series Oxygen Remover(Also known as the new integrated oxygen remover or integrated spray-type oxygen remover)Utilizing advanced design schemes and manufacturing processes, our deaerators offer numerous advantages over conventional industry standards. Several domestic companies, both established and under construction, have adopted the integrated deaerator technology, and all have achieved favorable operational results.

Two.Operating Principle

The deaerator generally includes two working processes.:

1.One-time Deoxygenation: Water not yet deoxygenated enters the deoxygenation pipeline via the inlet, is ejected through nozzles to form a mist, which then falls and passes through the liquid-vapor network, where it thoroughly mixes with the steam entering through the steam inlet. This process cools the mist to the deoxygenation temperature, causing most of the oxygen in the water to precipitate and be expelled through the exhaust port, thus completing the one-time deoxygenation.

2.Deaeration II: The purpose of secondary deaeration is to maintain the tank's temperature consistently at the deaeration level to maximize the deaeration effect. This is achieved by heating the already deaerated water through the auxiliary heating port at the bottom, causing any oxygen not removed in the primary deaeration to fully precipitate out, significantly reducing the oxygen content in the water. At this point, the secondary deaeration is complete.

Three.Deoxygenator structure

JSNCYThe Type Series Integrated Oxygen Remover consists of components such as a steam-water mixture heater, tank, soft water inlet coil, secondary heating and reboiling tube, thermal insulation board, anti-foaming device, level gauge, thermometer, automatic overflow tank, safety valve, and electric valve.
