A deaerator is a device that is used for the removal of dissolved gases like oxygen from a liquid. Thermal deaerators are commonly used to remove dissolved gases in feedwater for steam-generating boilers.

2019年5月22日 · In general, a deaerator is a device that is used for the removal of oxygen and other dissolved gases from the feedwater to steam generators. The deaerator is part of the feedwater heating system. It is usually situated between the last low pressure heater and feedwater booster pumps.

2019年8月9日 · Deaerators is commonly employed in any chemical process industry or in Power Plants wherever boiler is utilized for steam production from boiler feed water. Deaerator solves the aim of removal of unwanted dissolved gases and dissolved oxygen from the boiler feed water before going in boilers.

2019年9月22日 · Deaerator is a mechanical equipment that removes dissolved gases mainly dissolved oxygen & other non-condensable gases from boiler feed water. Oxygen causes pitting type corrosion in feed water systems. The process of removing dissolved gases from water also known as mechanical Deaeration.

2024年10月1日 · Boiler deaerators commonly are used to remove oxygen and other gases from the water that feeds into boilers that generate steam. Deaerators are useful because they remove the gases that attach to the metallic components of the steam system and cause corrosion by forming oxides, or rust.

Deaerator is the device used to treat the feedwater before moving it into the boiler. What is Deaerator? Water is a universal solvent that contains many dissolved gases which are highly corrosive when exposed to the boiler and boiler systems components. In addition to these dissolved gases, water also contains many dissolved minerals.

2023年6月18日 · Deaerating Heater Definition: A deaerating heater (deaerator) is defined as a device that removes dissolved gases from boiler feedwater to prevent corrosion and improve efficiency. How It Works: Deaerating heaters use steam to heat the feedwater and strip dissolved gases, which are then vented away.

Basically, a deaerator is a pressure vessel system. The pressure and temperature inside it varies from design to design. It consists of four main inlets and outlets – a condensate inlet, a steam and gas vent, a steam inlet, and a safety relief valve.

2023年10月11日 · The purpose of installing a deaerator is to remove the oxygen dissolved in water prior to use as feed in the boiler. Aerators work on two principles and those are Hendry’s Law and Gas solubility. let us discuss the working principle of deaerators in detail and how there are applied the deaeration process. 1. Hendry law.

Deaerators are large, tank-car-shaped, pressure vessels designed to produce preheated boiler feed water and bolster the efficiency of the boiler’s operation. In addition to preheating the feedwater, deaerators remove oxygen and carbon dioxide.
