    OD25MM CFB HF Welding Spiral Fin Tube For Power Plants


    Boiler Spare Parts High Frequency Welding Spiral Fin Tube For Power Plants

    Introduction


    Compact Structure Heat Exchanger H Finned Tube Economizer for CFB Boiler has won the title of high-tech products, and received a patent for utility model and design.

    H-economizer, also known as H-fin tube, H-type finned tubes, it is to have between two steel circular symmetry with fluorescent tubes welded together to form fins (fin-or butterfly-chip) positive shape Much like letter "H", so called H-fin tube.
    HTEG work closely with generators and power stations when considering retrofit or replacement units to offer the latest designs to maximize performance and effiency. The steel H product had evolved to enable the best possible engineering solutions. Bespoke fin shapes can be developed to suit individual applications.



    Application
    Compact Structure Heat Exchanger H Finned Tube Economizer for CFB Boiler used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.

    Procedure


    1Economisers also reduce the potential of thermal shock and strong water temperature fluctuations as the feed water enters the drum or waterwalls.
    2Increasingly stringent environmental regulations limiting nitrogen oxides and sulfur dioxide emission can also affect economizer design.
    3The gas-side heat transfer coefficient is much less than water side heat transfer coefficient. To compensate this, outer surface of the tubes may be finned to increase the surface area of heat transfer.
    4The ultimate goal of economizer design is to achieve the necessary heat transfer at minimum cost.
    5A key design criterion for economizer is maximum allowable flue gas velocity. Higher velocity provide better heat transfer and reduce capital cost.
