Boiler Spiral Fin Tube heat exchanger elements maintain a high capacity for heat transfer, possess superior self-cleaning properties and retain the ability to effect flue gas waste heat recovery in boiler renovations. Convective heat transfer coefficient is proportional to fin pitch, but inversely proportional to fin height and fin width. Integrated heat transfer capacity is related to fin efficiency, convective heat transfer coefficient and finned ratio. Pressure drop increases with the increase of fin height and fin width.
In order to improve the heat exchange efficiency and extend surface heat transfer,finned tubes have been widely used in boilers and waste heat recovery in recent years. finned tubes are derived largely from rectangle finned tubes. Because of their unique groove structure on the fin surface,finned tubes have excellent anti-wear and anti-fouling performance.

Our Advantages
1.Ensure sealing of furnace wall and reduce air leakage in combustion chamber.
2.Realize full water cooling of the combustion chamber, which is helpful to prevent coke formation in the case of intensified combustion.
3.Small capacity of heat storage, fast heating of combustion chamber and rapid cooling, can shorten the cooling time of boiler start and stop.
4.It is appropriate to use pipe furnace wall, which greatly reduces the load of boiler frame and is convenient for suspension.
5.Compared with the optical tube, the heat absorption capacity of the tube is improved.
6.The pre-combination degree of boiler components is improved, which is convenient and reduces the installation workload.
