Corrosionpedia - What is an Unfired Pressure Vessel

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.
