H finned tube is also called square finned tube to recover the waste heat of exhaust gas from power station boilers, industrial boilers, industrial kilns, ship power plants, etc., and effectively improve the utilization rate of fuel, and the enhanced heat exchange is arranged at the tail of the system flue element. Due to the characteristics of the convective heat transfer of the low-temperature flue gas-that is, the heat release coefficient a1 of the flue gas to the tube wall is much smaller than the heat release coefficient a2 of the tube wall to the steam and waterside, the use of an extended heating surface on the flue gas side is very effective necessary. The "economizers" (also called economizers) currently used in boilers include smooth tubes, spiral fin tubes, cast iron fin tubes, membrane wall tubes, etc. Except for the smooth tube type, the rest all Expand the heating surface structure.

The shortcomings of welded steel spiral fin tubes in practical application are mainly that the expansion of the surface area is restricted by the manufacturing process. The spiral fins wound on the tube are difficult to remove dust, which is easy to cause dust accumulation and blockage, and its flue gas side The flow resistance of the gas is high, so its application range is greatly affected by the fuel quality. Its advantages are high productivity, fewer manufacturing processes, and high material utilization.

In the structural design of the finned tube, a separate structure is adopted for the dust-forming part of the tube, which overcomes the shortcomings of easy dust accumulation, dust blocking, and gas resistance of the spiral fin tube. In addition, the fins of the fin tube are in a cantilever beam structure. Under the action of pulsed airflow, the vibration of the fins is more beneficial to the treatment of dust staining.
