An Äager Brand ERGIL designs, and manufactures two basic types of deaerator which also called deaerator tank, boiler feedwater deaerator or deaerator vessels tray-type and spray-type. These furnished consisting of perforated trays and vent condenser with the internal spray distribution system, storage tank, downcomers, and pressure equalizing piping between the deaerator and feed water.
Tray-Type includes a vertical domed deaeration section mounted on top of a horizontal cylindrical vessel. This serves as the deaerated boiler feed removes undissolved oxygen and raises the temperature of the feedwater. The system can be reduced operating costs by recovering flash steam when it is returned by high-temperature condensate. Also, it requires less boiler fuel to convert the feedwater to a usable steam water storage tank.
Spray-Type consists only of a horizontal cylindrical vessel that serves as both the deaeration section and the boiler feedwater storage tank. Whether it is a refinery application or a power plant, ERGIL’s deaerators are engineered as per customer specifications.
Pressure relief doors are furnished in the tray enclosure as storage tanks are required.
Self-draining perforated trays are provided. These trays are securely fixed in place and deflectors shall
be provided to protect trays from direct impingement of steam and feedwater entering the deaerator and feedwater Storage Tank.
Adequate spacing is provided between inlet fluid connections and deaerating components to prevent damage due to transient conditions, flashing or high velocities.
