Deaerator (options)

A deaerator comprising:

• a tank with an outlet fitting and a steam source,
• a deaerator column mounted on the tank
• wherein the deaerator column comprises a water inlet fitting and a vapor blowdown fitting, wherein the deaerator column further comprises lower and upper deaeration sections wherein the upper deaeration section comprises a first pressure tray and a first distribution tray and wherein the lower deaeration section comprises a second pressure tray and a second distribution tray, wherein the upper deaeration section comprises a first jet chamber formed in the area between the first pressure tray and the first distribution tray and wherein the lower deaeration section comprises a second jet chamber formed in the area between the second pressure tray and the second distribution tray, wherein the upper deaeration section comprises a first random element packing and wherein the lower deaeration section comprises a second random element packing,
• wherein the upper and lower deaeration sections are separated by a hydraulic seal formed by the edge of the first pressure tray and a hydraulic seal projection connected to an upper wall of the deaerator column, wherein the water inlet fitting and the vapor blowdown fitting are located inside the hydraulic seal projection and wherein a steam blowdown fitting is located outside of the hydraulic seal projection,
• wherein the hydraulic seal projection has openings the lower edges of which are located higher than the upper edge of the hydraulic seal.
