The top water wall headers in water tube boiler have a mixture of steam and water and this is returned to the steam drum via tubes known as risers. Superheater Tubes: Once water gets converted to steam, its temperature needs to be raised further to pump in more energy in the steam and this is done by imparting thermal energy to the steam in the form of superheat.

In water-tube boilers, the superheater may be an additional pendant suspended in the furnace area where the hot gases will provide the degree of superheat required (see Figure 3.4.4). In other cases, for example in CHP schemes where the gas turbine exhaust gases are relatively cool, a separately fired superheater may be needed to provide the additional heat.

Soluble-salt deposits may form at a superheater tube inlet as a result of excessive entrainment of boiler water solids with the steam. This can result in restricted flow. However, overheating and direct oxidation failures may occur in areas distinctly removed from the blockage, such as the bottom loops or the hottest areas of the superheater tubes.
