    Air Preheater Tube Bundle For Steel Mill Boiler Pressure Parts Stainless Steel With ASME Standard

     
    Product Description
     
    Air pre-heater is a kind of equipment used to improve the heat exchange performance and reduce energy consumption of the boiler, which means that the flue gas in the tail flue of the boiler will preheat the air before entering the boiler to a certain temperature through the internal radiator. Air preheater is generally divided into three types: plate type, rotary type and tube type. Taking the rotary type as an example, the working principle of air preheater is introduced. A large number of unburned combustibles will deposit on the heat transfer elements, which may cause the air preheater to ignite. The causes of ignition and the countermeasures are described in detail. The shutdown analysis and air leakage control are also introduced in detail.

     

    Different types


    For the use in Steam Generators (boilers)in Thermal power stations of Utility power stations, there are two types of design of the Airpreheaters. One is a tubular type built into the boiler outlet Flue_gas ducting and another one is of the regenerative type known as Ljungstrom (named after the name of inventor) Regenerative Air Pre Heater(RAPH),a rotating type. This may be horizontal (now very common in power generation utilities) or vertical.

    Product advantages


     

     

    The recovery of waste heat from the flue gas and heating the air required for Boiler In an air heater gives the following advantages.

    • The Boiler efficiency is increased.
    • More stable combustion in furnace.
    • The combustion is intensified with the use of hot air.
    • Lower grades of coals can be burnt efficiently with hot-air.
    • The use of hot air, improves the heat transfer rate and so less heat transfer area will be required.
    • The combustion is made complete with negligible amount of carbon in ash.
    • Faster load variations are possible.
    • The coal can be dried effectively for easy pulverization and combustion.

     Benefits

    1. Improved combustion rate and then increases steam generations rate of boiler.

    2. Due to higher temperature of air, furnance temperature increases, so low grade coal can be burnt efficiently.

    3. Air heated by heat of exhaust gases.It reduces fuel consumptions.Therfore thermal efficiency of boiler increased.

    4. Saving in fuel consumption and Increased steam generation capacity.
