    Description

     

    For boilers in large power stations, superheaters and reheaters are necessary parts, to a large extend, they have influced the safety and economy of boilers. Superheaters are the heating surfaces which heat the main steam from the surnatured temperature to the rated superheated temperature, and the reheaters are the heating surfaces which heat the exaust from the steam turbine high pressure cylinder to a certain temperature.When running conditions like boiler loads, coal types change, it is to adjust them to make sure the outlet temperature at the rated level of -10-+5 degrees.

     

    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.

     

    Super heater types:
    1. Radiant super heater: it is the earliest type of super heater and it is located above or behind banks of water tubes to protection them from direct flam or fire.
    Parameters that increases the convection

    a. Increasing the fuel-and air flow (combustion gas flow)
    b. Increasing the mass flow rate of the steam

    Radiation is mainly dependent on the flam temperature. as the steam flow rate increases the exit temperature become lower.
    Radiant super heater
    They are placed exposed to the heat source whcih requires the improvement of metal temperatures.

    Radiant and convetive super heaters and reheaters are used for high temperature steam.
    The accessory of high temperature radiant steam super heater in boiler

    It is made up of snake-like tubes (carbon steel, alloy steel or heat-resistant steel, etc.) and collection boxes and other supporting material. Tubes generally have φ32, φ38, φ42 or other types of specifications, according to user's needs separately.

    Reheaters
    They are the sane as the super heaters but as their exit temperature is a little bit less than super heaters and their pressure is 20% -25% less than the super heater, they can stand less quality material alloys.

    Application:
    Steam super heater is consisted of dense tube coils and is placed in the flue under the tempearture 450ºC-1000ºC.
    For power plant boiler capacity over 10Mpa, platen and coiled superheater are usually adopted.

     

    • Low-Temperature Superheater
    • Platen Superheater
    • High-Temperature Superheater
    • Coil Type Heat Exchanger
    • Steam Superheater
    • Roof Superheater
