EN 13445 UNFIRED PRESSURE VESSELS PDF

An unfired pressure vessel is any type of pressure vessel that is not fired. This means that they are not exposed to combustion or burner fire. Since it is an unfired vessel, there is a lesser risk of overheating. Unfired pressure vessels are very helpful in preventing corrosion by being an instrument of heat exchange. With these vessels, the occurrence of corrosion due to extremely high temperatures and other related factors can be prevented.

An unfired pressure vessel is any type of pressure vessel that is not fired. This means that they are not exposed to combustion or burner fire. Since it is an unfired vessel, there is a lesser risk of overheating. Unfired pressure vessels are very helpful in preventing corrosion by being an instrument of heat exchange.

With these vessels, the occurrence of corrosion due to extremely high temperatures and other related factors can be prevented. It can be a single chamber or composed of more. There are two forms of pressure vessels: fired and unfired. A fired pressure vessel is partially or totally open to burners and combustion gases and is prone to overheating. Examples of fired vessels include thermal oil heaters related to organic liquid piping systems as well as boilers that are used to generate hot water or steam.

On the other hand, unfired pressure vessels can act like heat exchangers, used to cool and heat fluid when combined with another fluid. These usually consist of several adjacent chambers and tube bundles. Another example of an unfired pressure vessel is a steam generator that is related to the piping systems for producing steam. Steam generators are used more often than boilers in generating steam, since these are safer alternatives and capable of reducing the extent of damage associated with corrosion.

Unfired pressure vessels are commonly seen in industrial settings that deal with: Machinery pressurized equipment.
