High Heating Transfer Efficiency Boiler Fin Tube With Bending SA179
Fin Tube Description
1.Finned Tube Heat Exchangers consist of a shell and finned tubes assembly.
2.Fins are used to increase the effective surface area of heat exchanger tubing.
3.Finned tubes are used when the heat transfer coefficient on the outside of the tubes is appreciably lower than that on the inside;as in heat transfer from a liquid to a gas,vapor to a gas ,such as steam to air heat exchanger, thermic fluid to air heat exchanger, when an extended surface is needed on only one fluid side or when the operating pressure needs to be contained on one fluid side.
H-type finned 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.
H-type tube, has a high rate of fusion welds and weld tensile strength. There is little contact resistance, and heat transfer performance and scalability are additional advantages. The H-fin tube is assembled with the H economizer, which has high efficiency, low resistance, and light weight. Compared to the traditional fin tube or spiral tube the H-fin tube can greatly expand the heating surface. When the extent of the effect of heat transfer is the same. The H-fin tube economizer takes up less space. In addition to the H economizer, H superheater, H air heater, and many other products. The H-fin tube has been included in the “Chinese high-tech product catalog”
