1. What Is A Boiler Deaerator Tank?

A boiler deaerator tank is an essential component in steam boiler systems, especially in large industrial settings. Its main purpose is to eliminate dissolved gases, primarily oxygen and carbon dioxide, from the feedwater used in the boiler. This is critical because these dissolved gases can lead to corrosion within the boiler system, resulting in decreased efficiency, higher maintenance expenses, and potentially hazardous operating conditions.

Removing dissolved oxygen and carbon dioxide helps maintain the integrity of the steam system’s metallic components and extend the lifespan of the boiler. Boiler deaerator tank achieves this by preventing the gases from attaching to the metallic components of the steam system and forming oxides or rust, which are responsible for corrosion. Since both oxygen and carbon dioxide contribute to corrosion, most boiler deaerators are designed to remove oxygen to levels that effectively eliminate carbon dioxide as well.

Boiler deaerator tank can effectively eliminate these dissolved gases to ensure the integrity and longevity of the boiler system. It helps minimize the risk of corrosion-related issues and ensures the boiler operates at optimal performance levels. This, in turn, enhances efficiency, reduces maintenance requirements, and promotes safe operation.

2. How Does Boiler Deaerator Tanks Work?

The design of an efficient boiler deaerator system is influenced by the quantity of gases to be removed and the desired final oxygen gas concentration. This is determined by the ratio of makeup water to returned condensate and the operating pressure of the deaerator tank.

In a steam boiler deaerator, steam is utilized to heat the water to its saturation temperature corresponding to the steam pressure in the deaerator. This steam also helps in scrubbing out and carrying away dissolved gases. The direction of steam flow can be parallel, cross, or counter to the water flow within the deaerator. The deaerator consists of three main sections: the deaeration section, a storage tank, and a vent. In the deaeration section, steam bubbles through the water, providing both heating and agitation. The steam is then cooled by incoming water and condensed at the vent condenser. Noncondensable gases and some steam are released through the vent.

The steam supplied to the boiler deaerator serves two purposes: physical stripping action and heating the mixture of returned condensate and makeup water to saturation temperature. While most of the steam will condense, a small portion (typically 5% to 14%) needs to be vented to meet the stripping requirements. During the design process, the necessary steam quantity is calculated for heating purposes, ensuring that it is adequate for effective stripping as well. If the condensate return rate is high (over 80%) and the condensate pressure is significantly higher than the deaerator pressure, the steam required for heating purposes is minimal, and provisions can be made to condense the excess flash steam.

The design of a boiler deaerator system considers factors such as gas removal requirements, desired oxygen concentration, makeup water to condensate ratio, and deaerator tank pressure. Steam is used to heat the water and remove dissolved gases through physical stripping. Proper calculations are made to determine the necessary steam quantity for heating and stripping, with provisions for condensing excess flash steam if applicable.

3. What Are the Advantages of Boiler Deaerator Tank?

EPCB boiler deaerator offers exceptional deaeration efficiency, stable operation, and adaptability to different conditions. It excels in heat and mass transfer, reducing steam exhaust and energy consumption. With a trusted brand and a one-year warranty, users can rely on its high-quality performance and longevity.

3.1 High Deaeration Efficiency

The deaerator demonstrates excellent efficiency in removing oxygen from the feed water, ensuring a 100% qualified rate of oxygen content. For atmospheric deaerators, the oxygen content in the feed water is maintained below 15 Ω / L, while for pressure deaerators, it is below 7 Ω / L. This guarantees high-quality feed water.

3.2 Stable and Vibration-Free Operation

The deaerator operates smoothly without any vibrations. It is suitable for both negative pressure start-up and sliding pressure operation, eliminating the need for complex manual adjustments during startup and operation.

3.3 Versatile and Flexible

The deaerator offers great adaptability and is not overly demanding in terms of water quality or temperature requirements. It can be operated for short periods at approximately 50% over its rated capacity, providing flexibility in various operational scenarios.

3.4 Efficient Heat and Mass Transfer

The rotary membrane deaerator maintains water in a turbulent state, resulting in a large heat exchange surface area. This enhances the heat and mass transfer efficiency, leading to minimal steam exhaust and lower energy consumption.

3.5 Trusted Supplier with Quality Assurance

The deaerator is manufactured by the Trusted Chinese brand, ensuring reliability and quality. It has a high deaeration efficiency and a longer service life, providing peace of mind for users. Additionally, it comes with a one-year warranty, further guaranteeing its performance and durability.

4. What Are The Benefits of A Boiler Deaerator Tank?

Boiler beaerator tanks provide several benefits to boiler systems, including the reduction of corrosion, improved efficiency, increased equipment lifespan, cost savings, and enhanced steam quality. These advantages make deaerators a crucial component in ensuring the optimal performance and longevity of steam boilers.

4.1 Corrosion Control for Steam Boiler

One of the key benefits of using a boiler deaerator tank in a boiler system is the reduction of corrosion. Dissolved oxygen in water can react with the metal surfaces of the boiler, leading to corrosion and degradation. By removing oxygen, deaerators help prevent this corrosive process, ensuring the longevity and reliability of the steam boiler.

4.2 Efficiency Improvement of Steam Boilers

Steam boiler deaerator tanks also enhance the efficiency of steam boilers. The presence of dissolved oxygen can hinder heat transfer and decrease overall boiler efficiency. By removing the oxygen, deaerators optimize heat transfer and improve the overall energy efficiency of the system. This results in cost savings and increased operational efficiency.

4.3 Increase the lifespan of steam boilers

Steam boiler deaerator tanks effectively increase the lifespan of steam boilers by preventing damage caused by oxygen-related corrosion. By maintaining clean and corrosion-free surfaces, the boiler components can operate at peak performance for an extended period, reducing the need for frequent repairs or replacements.

4.4 Operating Costs Reduction

Deaerator tanks contribute to the reduction of operating costs associated with steam boilers. By preventing corrosion and scaling, they minimize the need for chemical treatments and frequent cleaning, resulting in cost savings over time.

Keep Steam Quality

Steam boiler eaerator tanks improve the quality of steam produced by the boiler system. By removing dissolved gases, such as oxygen and carbon dioxide, they ensure that the steam generated is of high quality, free from contaminants that could potentially affect downstream processes or equipment.
