    Spiral Finned Tube Economiser For Boiler , Economizer Heat Exchanger High Efficiency

    CFB Boiler Spiral Finned Tube Cast Iron stack Economiser factory optional device High efficiency Annealing treatment

    Spiral Finned Tube Economizer


    The economizer can be installed at the rear of exhaust gas stovepipe to recovery exhaust gas heat,increase the electricity output,lower the coal consumption.spiral finned tube economizer is a new and efficient heat transfer equipment, which is a good solution to the light tube economizer because of badly worn, short life and other shortcomings.


    Details


    Heat transfer area can be greatly extended, reducing the volume and angle fittings, enhanced heat transfer. As gas flows through the finned tube forming the boundary layer, resulting in the vortex.Adapting to wide temperature, high pressure;impact resistance low flue gas resistance.


    Characteristics

    a) Dimensional range

    Diameter6 – 102 mm(0.24 – 4.02 in.)
    Wall thickness0.3 – 9 mm(0.01 – 0.33 in.)
    Lengthup to 25,000 mm(984 in.)

    b) Annealing conditions

    • Hard
    • Annealed conforming to standards (soft, half-hard, blank, etc.)
    • According to customer specifications


    Purpose


    Using an economizer does not just prevent heat loss — it can also extend the life of the boiler. Stresses from using cooler temperature make-up water, known as “thermal shock”, can subject wear and tear on the boiler’s structural integrity over time. This hammering “shock” effect occurs as the boiler’s fixed tube-sheets and fire-tubes rapidly contract from the sudden make-up of cooler temperature water. However, when this water is pre-heated, the temperature differential is far less extreme, putting less strain on the boiler and giving it a longer operating life.


    Quality Control
