A deaerator is a device that is used to remove dissolved gases, primarily oxygen and carbon dioxide, from feedwater in steam generating systems. This removal is essential in preventing corrosion in the boiler system and maintaining the efficiency of the steam generating process.
The functioning of a deaerator involves heated feedwater entering the device and being sprayed in a thin film over a large surface area to allow for the release of dissolved gases. These gases are then vented out of the system, leaving behind deaerated water that is ready to be used in the boiler.
Importance of Deaeration
Proper deaeration of feedwater is critical in ensuring the longevity and efficiency of a steam generating system. When dissolved gases are present in the boiler feedwater, they can lead to oxygen pitting corrosion, which can cause costly damage to the boiler components. Additionally, the presence of gases can reduce the heat transfer efficiency of the system, leading to increased energy costs.
Types of Deaerators
There are several types of deaerators available, including tray-type deaerators, spray-type deaerators, and vacuum deaerators. Each type has its unique design and method of removing dissolved gases from the feedwater. Tray-type deaerators use a series of trays to expose the feedwater to steam and remove gases, while spray-type deaerators use a spray nozzle to disperse the water in a thin film for optimal deaeration. Vacuum deaerators operate by creating a vacuum to lower the boiling point of water, allowing for the release of gases at lower temperatures.
Maintenance of Deaerators
Proper maintenance of deaerators is essential to ensure they continue to function effectively. This includes regular inspections, cleaning of trays or nozzles, checking for proper venting of gases, and monitoring water chemistry to prevent corrosion. By maintaining a deaerator in optimal condition, the overall efficiency and reliability of the steam generating system can be preserved.
In conclusion, a deaerator plays a crucial role in steam generating systems by removing dissolved gases from feedwater to prevent corrosion and improve efficiency. Understanding the importance of deaeration, the types of deaerators available, and the necessary maintenance practices is essential for ensuring the long-term operation of a boiler system.
