  • Steam Superheater in Boiler: Role, Benefits, Types

    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 Learn More
