Steam side burning is a chemical reaction between steam and the tube metal. It is caused by excessive heat input or poor circulation, resulting in insufficient flow to cool the tubes. Under such conditions, an insulating superheated steam film develops.

Steam Purity. Purity or chemistry requirements for steam can be as simple as a specified maximum moisture content, or can include maximum concentrations for a variety of chemical species. Often, for low pressure building or process heater steam, only a maximum moisture content is specified. This may be as high as 0.5% or as low as 0.1%.
