    Boiler Superheater and Reheater for Coal-fired CFB Boilers

     

     

     

    Description

     

    The function of Super heater in the thermal power plant is to remove the last traces of moisture from the saturated steam coming out of boiler and to increase its temperature above saturation temperature as per requirement at inlet of steam turbine.

     

    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.

    Principle

     

    • Principle of superheater is similar to steam generating tubes of boiler.

    The hot gases at high temperature sweep over superheater tubes and raise the temperature of steam which magnitude depends upon exit gas temperature leaving the superheater and gas velocity.

    Application

     

    use for heating saturated steam, steam temperature could be up to 900 degree C.

    Superheater Capacity Upgrades to Increase Power Generation

     

    Send us required technical data, such as steam capacity, presure, required temperature etc. We will design accordingly.

     

    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.
