Deaerator
Deaerator is special equipment designed to remove corrosive and aggressive gases, such as oxygen and free carbon dioxide, from the water that is used to make up steam boilers and the heating system.
The deaerator can be operated in two modes:
- Manual operation mode, in which the deaeration plant is operated with the odour trap controlled by the operator;
- Automatic operation, where atmospheric deaerators are equipped with special control panels. These panels perform automation functions, including deaerator level control, control of heating and bubbling steam flow rates, and control of valves and safety devices.
The standard scope of delivery of the atmospheric deaerator includes:
- Deaeration tank with a volume to be selected by the customer. The deaeration tank has elliptical bottoms and is equipped with a hatch for inspection of internal surfaces. A barbotage device is installed in the lower part of the tank;
- Deaeration column with internal devices made of stainless steel;
- Vapour cooler with heat exchange tubes made of stainless steel or brass (depending on customer’s choice);
- A safety device, also known as the odour trap. The odour trap is only fitted to deaerators with simplified automation and is not included when the deaerator is equipped with control panels.
