Water Handbook - Boiler Feedwater Deaeration | SUEZ

In this way water is reduced to thin films and droplets which promote the release of dissolved gases. The released gases and water vapor are removed through the vacuum which is maintained by steam jet eductors or vacuum pumps depending on the size of the system. Vacuum deaerators remove oxygen less efficiently than pressure units.

basic principle of heating hot water boiler

08/09/2020 · The boiler is a closed vessel where the water is stored. Hot gases are formed by burning fuel in the furnace. These gases are made to come in contact with the water vessel the point where the heat transfer takes place between the steam and water. Thus the boilers basic principle is to convert water into steam with heat energy.
