Lord Fin Tube-Single H finned tube

In order to make full use of the heat energy in the boiler, it is usually necessary to set some fins on the pipe to form a kind of economizer, and use these fins to improve the heat transfer efficiency. In the traditional boiler economizer and all kinds of heat exchanger, the fins are usually set parallel to the pipe axis to form a longitudinal rib structure; or sometimes the fins are wound on the pipe to form a spiral structure. These structures can improve the heat transfer efficiency, but can not solve the contradiction of expanding the heating surface and reducing ash deposition at the same time. Among them, the longitudinal rib structure can reduce the ash deposition, and the heating area is also increased compared with the smooth tube, but the increase is very limited, which often can not meet the actual needs; the spiral structure can greatly increase the heating area of the pipeline, but its serious ash deposition problem makes the flue gas channel of the economizer rapidly smaller, increases the ventilation resistance, and leads to the rapid decline of heat exchange capacity, thus increasing the energy consumption, then the frequency of boiler maintenance and parts replacement is added.

double H types finned tubeH-type finned tubes are divided into single H finned tube and double H types finned tube. They are widely used in the flue gas waste heat recovery system of power station boilers, industrial boilers, kilns, ship power plants, etc. as enhanced heat exchange elements. So why is H-shaped finned tube so widely used? Because of its unique structure, the structure is stable and not easy to deform, and the heat transfer efficiency is high!

The H-shaped fin tube adopts a unique sawtooth structure. The fins are welded on the surface of the steel pipe. The welding part of the fins adopts multiple sawtooth shapes. The heating surface is evenly welded and firmly. The welding angle surface is smooth, and there is no slag, air hole, welding tumor, welding The fusion rate is as high as 98% and has a good heat transfer coefficient.

At the same time, the H-shaped finned tubes are arranged in-line. The fins divide the surface space of the steel pipe into several small areas, which have a flow equalizing effect on the flue gas. Compared with the staggered arrangement of smooth tubes or spiral fins, the H-shaped fins The sheet tube has good steel structure and is resistant to deformation, and has a longer wear life.
