    Alloy Steel Pin Type Water Wall Panels For Reduce Heat Loss , High Efficient Heat Exchange

     

     

    Product Description


    Water Wall Panels are used in modern day Boilers to reduce heat loss due to their gas tight nature and reduce insulation costs. We fabricate Water Wall Panels using automatic Fin to tubes welding machines and large Tube Panel Benders to achieve desired shape of panels which can have Stub Welded to Headers. We supply Panels with integrated manhole openings in the panels.

    Introduce


    Water wall panels with pins usually laid vertically on the inner wall of the furnace wall, it is mainly used to absorb the radiant heat emitted by the flame and high-temperature flue gas in the furnace.It is the main type of evaporating heating surface of all kinds of modern boilers and the basic component of boiler water circulation loop.Because of both cooling and protection of the furnace wall, so the name.

    The water wall was originally designed not to be heated, but to cool the furnace from high temperature damage.Later, because of its good heat exchange function, it gradually replaced the steam drum as the main heating part of the boiler.

     

    The evaporative heating surface, which is laid on the inner wall of boiler chamber and consists of many parallel pipes.The function of water wall is to absorb the radiant heat of high temperature flame or flue gas in the furnace chamber, generate steam or hot water in the pipe, and reduce the temperature of the furnace wall to protect the furnace wall.In a large capacity boiler, the flame temperature in the furnace is very high, the intensity of heat radiation is very large.Forty to fifty percent or more of the heat in the boiler is absorbed by the water wall.Except for a few small capacity boilers, modern water tube boilers take water cooling wall as the main heating surface of evaporation.

     
     
    Types

    According to the type of structure, there are three main types of light tube type, membrane type and thorn tube type.The water wall of optical tube is composed of a whole row of seamless steel tubes, which has the simplest structure.Membrane type water wall is a lot of water wall fins rolled good tube spot welding each other together, so as to become a sealed composite heating surface, not only can improve the air tightness of the furnace, reduce air leakage, but also can better protect the furnace wall, so that the furnace wall weight reduction, structure simplification;Barbed tube water wall is in the water wall pipe welding a lot of long 20 ~ 25mm, diameter of 6 ~ 12mm pin, and then apply chrome ore refractory plastic, in order to reduce the water wall of the part of the heat absorption, improve the temperature of the combustion zone, suitable for fuel fire especially difficult occasions or some liquid slag furnace.Press to arrange a place, have type of add a wall and lie between wall type (namely double sided heating) water cooling wall two kinds.The former is mostly embedded in the inner wall of the furnace wall and absorbs heat on one side.The latter is mostly installed in the middle of the large boiler furnace, the whole furnace is separated into two independent parts, heating on both sides.

    Features


     

    1. Strength calculation report with applied materials information;
    2. 100%NDT(non-destructive inspection) report of steel plate, tube and welding rod;
    3. 100%X-ray inspection report (welding seam): to ensure the quality of the entire boiler;
    4. Hydraulic test report: ensure the standard working pressure and safet

     

     

     

    Adavantages


    1.ensure the sealing of furnace wall and reduce air leakage in combustion chamber.

    2.realize full water cooling in the combustion chamber, which is conducive to preventing coking under the condition of intensified combustion.

    3.low heat storage capacity, fast heating and cooling of the combustion chamber, which can shorten the cooling time of the boiler starting and stopping.

    4.it is suitable to use tube-laying furnace wall, which greatly reduces the load of boiler frame and facilitates suspension.

    5.compared with the light pipe, the heat absorption capacity of the pipe is improved.

    6.improve the pre-assembly degree of boiler components, facilitate and reduce the installation workload.
