Our replacement parts are engineered to match the dimensional fit and flow performance of the original equipment, providing a direct replacement with an expected service life of more than 20 years under normal operating conditions. Many spray valves and tray assemblies are stocked for immediate shipment to minimize downtime.
A horizontal tray deaerator mounted on a storage tank highlights the HEI‑compliant design, which prevents unrated water from contacting carbon steel, and shows how the tray stack creates a thin water film for effective counter‑flow steam contact. The hold‑down system keeps trays securely in place without special tools, preventing tray upset. The video also covers the first‑stage spray distribution, the importance of engineered spray valve arrangements, and how unwanted gases are vented as clean, deaerated water flows into the storage tank, achieving oxygen levels as low as 7 ppb.
How a two stage spray and tray deaerator removes non condensable gases from boiler feedwater. It shows how water enters the first stage through spray valves that create fine droplets for efficient heating and gas release. The water then flows into the second stage, where steam is introduced through distribution pipes beneath the water level. As the steam mixes with the incoming water, remaining gases are removed and vented from the top of the vessel. The video highlights how proper spray arrangement and steam distribution support reliable deaeration and low oxygen levels.
