Introduction

A horizontal deaerator is a critical boiler feed water treatment equipment designed to remove dissolved oxygen and carbon dioxide from water. Without effective deaeration, these gases cause corrosion in boilers, heat exchangers, and pipelines, leading to reduced efficiency and shortened equipment lifespan.

Our spray-tray horizontal deaerator combines spray-type and tray-type technology, ensuring maximum oxygen removal efficiency and reliable performance. This makes it the preferred choice for power plants, petrochemical facilities, metallurgy, and district heating systems that require high-capacity and stable operation.

Working Principle of a Horizontal Deaerator

1. Water Spray Process: Boiler feed water enters through spray nozzles, breaking into fine droplets. These droplets come into direct contact with heating steam, quickly releasing dissolved gases.

2. Tray Section Process: The water then flows across multiple trays, where it fully exchanges heat and mass with rising steam, achieving deep oxygen removal.

3. Gas Discharge: Released oxygen, CO₂, and other non-condensable gases are vented out through the deaerator’s exhaust system.

4. Storage Tank: The deaerated water collects at the bottom tank and is continuously supplied to the boiler as feed water.

This process reduces oxygen content in feed water to ≤ 7 μg/L, fully meeting the strict requirements of power station boilers and industrial applications.

Key Features of Spray-Tray Horizontal Deaerator

• High Efficiency: Double deaeration effect through spray and tray sections.

• Energy Saving: Utilizes heating steam for both deaeration and preheating feed water, improving boiler efficiency.

• Large Capacity Design: Horizontal shell structure suitable for high water flow in large power plants.

• Durable & Safe: Prevents oxygen corrosion, extending the service life of boilers, pipelines, and pressure vessels.

• Easy Maintenance: Equipped with manholes and inspection openings for cleaning and servicing.

Applications
