    Description


    Superheater is a part of a boiler that heats the steam from the saturation temperature to the overheating temperature. It is also called a steam superheater.Superheater can be divided into convective type, radial type and semi-radial type according to heat transfer mode;According to the characteristics of the structure, it can be divided into serpentine pipe type, screen type, wall type and wall type.They are made up of parallel pipes and inlet and outlet manifold.

    Most industrial boilers do not have superheaters because many industrial processes and living facilities require only saturated steam.In power stations, locomotives and Marine boilers, superheater is usually installed to improve the circulating thermal efficiency of the whole steam power plant.

    Details


    • Superheating raises overall efficiency as well as avoids too much condensation in last stages of turbine which avoids blade erosion.
    • The heat of combustion gases from furnace is utilised for removal of moisture from steam and to superheat the steam.
    • Super-heaters ususlly have several tube circuits in parallel with one or more return bends,connected between headers.
    • Heat from the hot gases to the vapour in the surperheater is transferred at high temperatures.
    • Therefore promary section of superheater is arranged in counterflow and secondary section in parallel flow to reduce the temp.stressing of the tube wall.

     
    Differences


    Type Advantages Disadvantages Supporting method
    Pendant-type 1.Firm structural support 1. Flow blockage by condensed steam 2. Needs slow restart to purge the water that accumulates in the bottom. supported from above
    Inverted-type 1.Proper drainage of the condensed steam 1. Lack the structural rigidity, especially in high speed gas flow Supported from below
    Horizontal -type

    1. Proper drainage

    2. Good structural rigidity.

    1. They do not view the flam directly so they are mainly from the convective type Usually supported in the vertical gas ducts parallel to the main furnace.
     

     
     
    Functions


    1.Superheater is the saturated steam heated into a certain temperature of superheated steam equipment.

    2.After the saturated steam is heated into superheated steam, the working capacity of steam in the steam turbine is improved, that is, the useful enthalpy of steam in the steam turbine is increased, thus improving the cycle efficiency of the heat engine.

    3.In addition, the adoption of hot steam can also reduce the steam exhaust humidity of the steam turbine, avoid the corrosion of the steam turbine blade, and create favorable conditions for the further reduction of steam exhaust pressure and safe operation of the steam turbine.
