Fired Heaters are typically fired with refinery gas and/or fuel oil. Both fuels contain sulphur. The sulphur will be oxidized when burned to SO x which consists out 2-5% SO 3 and the remainder will be SO 2.When installing air preheating, it is important to protect the system for cold spot corrosion.The acidic part of the flue gas (SO 3) starts to condense at the acid dew point (ADP).
