    Product Introduce


    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.


    Product Description


    Using superheated steam can reduce the moisture content in the exhaust steam of steam turbine.Depends on the boiler superheated steam temperature pressure, evaporation, steel and high temperature resistant performance and fuel price comparison of steel, for power plant boiler, boiler in general is about 450 ℃, 4 million mpa;More than 10 million mpa boiler for 540 ~ 570 ℃.A handful of power station boiler also have higher superheat steam temperature (or even up to 650 ℃).



    Product Function&Features


    HDB thermal efficient steam super heater for coal fired boilers
    Specification:
    Super heaters are the one of the most important boiler sapre parts that improves the thermal efficiency. High temperature steam boiler radiant super heater is usually applied in high pressure power plant boiler.

    In the boiler, the role of super heater is to heat the saturated steam to a certain temperature of superheated steam to increase power plant efficiency. Repeater essentially further improves the thermal power plant cycle efficiency.

    Steam Super heater Coils: Super heater coils are used in a boiler to generate saturated steam. The super heater coils are specially used in Boilers of Power plant. We manufacture Super heater coils in various grades of Alloy steel and in stain less steel tubes with or without support & Header as per customer's drawing.


    Changes in boiler operating conditions, such as load level, fuel change, combustion condition change, etc., all have an impact on superheater outlet steam temperature, so in power station boilers there are means to adjust boiler outlet steam temperature to make it stable at the specified value.Commonly used means are:

    (1) with water jet or surface type temperature reducer directly adjust the steam temperature;

    (2) with the swing burner to change the temperature of the furnace outlet smoke;

    (3) with smoke recirculation adjustment superheater heat absorption.When the boiler load increases, the temperature rise value of the inlet and outlet steam of the flow superheater increases, while the temperature rise value of the radiant superheater decreases.


    If the convective superheater, radiant superheater and semi-radiant superheater are properly combined and configured, the outlet steam temperature can change less when the load and combustion conditions change.The heat absorption and steam flow rate of the parallel pipes in the superheater stack will be different in operation.In order to avoid excessive temperature in individual pipes, the superheater is divided into several pipe groups in large boilers. Steam of each pipe group is mixed with a collecting box outside the furnace and the steam guide pipe is used to make each pipe group transposition, so as to avoid excessive temperature difference between each pipe.


    Product 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.


    Details


    1Material compositionCarbon steel, alloy steel or heat-resistant steel, collection boxes and other supporting material. Tubes are customized types of specifications.
    2Design patternVertical or horizontal layout.
