Global Industrial Deaerators Market Strategic Research Report

Scope of the Report

The global Industrial Deaerators market size is predicted to grow from US$ 3,912 million in 2025 to US$ 5,651 million in 2032; it is expected to grow at a CAGR of 5.5% from 2026 to 2032.

In 2024, global industrial deaerator production reached 1.1131 million units, with an average selling price of US$3,411,785 per unit and a gross profit margin of 18.3%-35.8%. Upstream raw materials include stainless steel plates, seals, nozzles, and valves, supplied by Baosteel, TISCO Stainless Steel, and CNNC Sufa. Downstream customers include State Power Investment Corporation, Huaneng Group, and CGN; Sinopec, CNPC, and Wanhua Chemical; Tsingtao Brewery, Yili Group, and Coca-Cola; Hengrui Medicine, Yangtze River Pharmaceuticals, and Pfizer. Boilers play a vital role in power generation. To ensure proper operation and prevent corrosion, deaerators are often required. Deaerators are devices used to remove carbon dioxide, oxygen, and other gases from the feedwater supplied to the boiler. To prevent corrosion caused by these gases, deaerators are required. Removing these dissolved gases improves boiler efficiency and lifespan. There are two types of deaerators: thermal deaerators and vacuum deaerators. Thermal deaerators are further categorized as spray-type and tray-type. A spray deaerator is a cylindrical vessel used to remove dissolved gases from feedwater. Dissolved gases are removed by reducing the pressure or increasing the temperature inside the deaerator. Feedwater entering the deaerator flows through a draft section, where it undergoes a high-pressure steam treatment, which removes dissolved gases. A tray deaerator is a vertical dome located on a horizontal section of the vessel. The fundamental difference between tray-type and spray-type boilers is that tray-type boilers use both nozzles and trays. This combination of sprays and trays allows for better mixing of air and water (enhanced heat exchange), resulting in more precise removal of dissolved gases from the feedwater. A vacuum deaerator operates on the same principle as a tray-type deaerator, but uses a vacuum pump at the exhaust port to minimize exhaust losses. Minimizing exhaust losses improves boiler efficiency.

One of the main growth drivers of the deaerator system market is the rapid expansion of the power generation industry. With growing global energy demand, the number of new power plants has increased significantly, particularly in developing economies. Deaerator systems are crucial in these power plants, ensuring efficient boiler and turbine operation by preventing corrosion and maintaining system integrity. From a regional perspective, the Asia-Pacific deaerator system market is expected to experience significant growth during the forecast period. Rapid industrialization in the region, coupled with increasing investment in power generation infrastructure, is driving demand for deaerator systems. Countries such as China and India are leading this growth, driven by their large manufacturing sectors and ambitious energy projects. North America and Europe also offer significant market potential due to the ongoing modernization of existing power plants and stringent environmental regulations.
