Value Of Boiler Agent Feed Water

Corrosion within boilers - Lars Josefsson

2020-4-10 · The presence of oxygen and carbon dioxide can cause corrosion of the feed water, boiler or condensate systems. For all boilers it is essential to reduce the concentration of dissolved gases, particularly oxygen in the feed of lowest value possible by mechanical means followed by supplementary chemical treatment to remove the last traces of oxygen.

MARINE ENGINEERING KNOWLEDGE BY RAJAN -

Open the feed water valves and the air valve. Fill the boiler with feed water to approximately 50 mm below normal water level. The water level rises due to expansion when the boiler is heated. If the temperature difference between the boiler and feed water exceeds approximately 50ºC, the boiler must be filled very slowly.
