Boiler Deaerator

Product Details

One.Foreword

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 both the feed water system and the boiler. Oxygen in the feed water must be removed promptly, otherwise, it will corrode the boiler's feed water system and components. The corrosion produces iron oxide, which enters the boiler, settles or adheres 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 walls of the pipes, increasing the resistance coefficient. Severe pipe corrosion can even lead to pipeline accidents. The national regulations stipulate that the evaporation capacity is greater than or equal to2Steam boilers with a capacity of more than or equal to tons per hour and water temperature95℃All 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.JSNCYType Series Built-in Oxygen Remover(Also known as the new type internal oxygen remover, internal spray oxygen remover)Utilizing advanced design schemes and manufacturing processes, our deaerators offer numerous advantages over conventional industry standards. Currently, several domestic companies, both established and under construction, have adopted our integrated deaerator technology, and all have achieved excellent operational results.

Two.Operating Principle

The deaerator generally includes two working processes.:

1.A single oxygen removal: Water that has not been deoxygenated enters the deoxygenation pipeline through the inlet, is ejected through nozzles to form a mist, which then falls through the liquid-vapor mesh and thoroughly mixes with the steam entering through the steam inlet. This causes the misty water to reach the deoxygenation temperature, with most of the oxygen in the water precipitating out and being expelled through the exhaust port, thus completing the first stage of deoxygenation.

2.Deoxygenation Stage 2: The purpose of the second deoxygenation stage 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.Deoxygenator Structure

JSNCYThe Type Series Integrated Deaerator consists of components such as a steam-water mixing 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.

Four.Deaerator Advantages

1.Steam and liquid are instantly mixed and evenly distributed, rapid heating, high thermal efficiency,Energy-saving.

2.Carbonated beverage mixed heating steam pressure below,All pressure levels above the heated liquid are suitable for use.,And the steam pressure must be higher than the liquid pressure0.05～0.1MpaLimitations.

3.JSNCYThe inline oxygen remover features low vibration and noise.

4.JSNCYCompact built-in deoxygenator, Low investment required.

5.JSNCYType built-in oxygen remover with high temperature rise,Available100℃Above.

6.JSNCYThe built-in oxygen scavenger features a simple structure, is resistant to scaling, requires no maintenance, and has a long service life.

7.Utilizing low-pressure exhaust steam as a heat source for making hot water saves energy and protects the environment.

8.Due to the selection of models based on user parameters or custom design, the products offer good suitability for users, operate smoothly, and meet all user requirements.
