Thermal Deaerator

Product Details

One.Preface

DeaeratorBoilerOne of the key equipment in the heating system。

In the boiler feed water treatment process, deoxygenation is a critical step. Oxygen is a primary corrosive substance in the feed water system and boiler. The oxygen in the feed water must be removed quickly, otherwise, it will corrode the boiler feed water system and components. The corrosion will produce ferric oxide, which 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, pipeline accidents may occur. The national regulations stipulate that the evaporation capacity is greater than or equal to2Steam boiler with a capacity of more than or equal to tons per hour and water temperature95℃All of our hot water boilers are deoxygenated. Over the years, many boiler water treatment processes have been searching for a cost-effective deoxygenation method for ambient temperature water. Lianyungang Jiusheng Power Auxiliary Equipment Co., Ltd. has many years of experience in designing and manufacturing deoxygenators.JSNCYIntegrated Oxygen Remover Series(Also known as the new type integrated oxygen removal unit, integrated spray type oxygen removal unit)Utilizing advanced design and manufacturing techniques, our deaerator offers numerous advantages over conventional industry standards. Currently, several domestic companies, both established and under construction, have adopted our built-in deaerator technology, with all operational enterprises achieving excellent performance results.

Two.Working Principle

The deaerator generally includes two working processes.:

1.One-time Deaeration: Water not deoxygenated enters the deaeration pipeline through the inlet, is ejected as a mist through nozzles, and falls through the liquid-vapor mesh. It is thoroughly mixed with steam entering through the steam inlet, reaching the deaeration temperature. Most of the oxygen in the water is then extracted and expelled through the exhaust port, completing the one-time deaeration process.

2.Deoxygenation Stage 2: The purpose of the second deoxygenation is to maintain the tank's temperature consistently at the deoxygenation level to maximize the deoxygenation effect. This is achieved by heating the already deoxygenated water through the auxiliary heating port at the bottom, causing any undissolved oxygen from the initial deoxygenation to fully precipitate, significantly reducing the oxygen content in the water. At this point, the second deoxygenation is complete.

Three.Deaerator structure

JSNCYThe Type Series Integrated Deaerator is composed of components such as an air-water mixing heater, tank, soft water inlet pipe, secondary heating and reboiling tube, insulating board, antivapor-erosion device, liquid level gauge, thermometer, automatic overflow tank, safety valve, and electric valve.
